為了同時達成提高太陽能電池模組之結構強度及光利用率之目的，目前有在光伏電池片之間的間隙設置具反射性外表面之支撐結構的做法，這類支撐結構的剖面形狀需配合反射角度而設計為類三角形、梯形或其他中間寬兩端 窄的形狀。然而，為了達到一定的支撐力，這樣的設計無法將支撐結構上、下的支撐面過度縮小，入射至支撐結構之光線實質上仍僅有小部分能由反射性外表面反射至他處。因此，本發明在此提出一種太陽能模組支持結構與太陽能模組，其將反射面設置於支持結構的內部，而支持結構中位於反射面之外側的部分需是可透光的材料，藉此可兼顧太陽能電池模組之結構強度及光利用率的效果。 In order to achieve the purpose of improving the structural strength and light utilization rate of the solar cell module at the same time, there is currently a method of providing a support structure with a reflective outer surface in the gap between the photovoltaic cells. The cross-sectional shape of this type of support structure needs to match the reflection Angle is designed as triangle-like, trapezoidal or other middle wide ends Narrow shape. However, in order to achieve a certain support force, such a design cannot excessively reduce the support surfaces above and below the support structure. In fact, only a small part of the light incident on the support structure can be reflected from the reflective outer surface to other places. Therefore, the present invention proposes a solar module support structure and a solar module, the reflective surface is provided inside the support structure, and the portion of the support structure outside the reflective surface needs to be a light-transmissive material, thereby It can take into account the structural strength of solar cell modules and the effect of light utilization rate.

The first sub-portion 120a is transparent. The transparency of the first sub-portion 120a is to allow at least some specific wavelengths of sunlight (especially wavelengths that allow solar cells to be converted into electrical energy) to penetrate. The second sub-portion 130a may be a transparent material or an opaque material. The material of the second sub-portion 130a may be the same as or different from the material of the first sub-portion 120a. The first sub-portion 120a can be selected from high transparency, low reflectivity, and refractive index The polymer material of the packaging material near the solar module, wherein the material of the packaging material may be, for example, polyethylene vinyl acetate (EVA). For example, the material of the first sub-portion 120a may be optical acrylic or silicone rubber, where the optical acrylic is polymethyl methacrylate (PMMA). The refractive index of polymethyl methacrylate is 1.46, and the average reflectivity (Reflectivity) (%) is less than 2.0; the refractive index of silicone rubber is 1.41, and the average reflectivity (%) is less than 2.0.

第一子部120a與第二子部130a之間具有第一介面140a，此第一介面140a具有第一光再導向結構142a。第一介面140a可為平面或可為弧面，例如凹弧面或凸弧面。在一些例子中，第一光再導向結構142a可為反射材料層(例如金屬層)或具有反射效果的微結構層。第一光再導向結構142a可變更由第一支撐表面150a之第一表面子區152a進入支持主體110a之光線的方向，而使光線轉而由側面170a的第一側子區172a離開支持主體110a。在圖1所示之實施例中，第二子部130a之剖面呈三角形，第一子部120a則環設於第二子部130a上。因此，第一子部120a與第二子部130a之間的第一介面140a與第一支撐表面150a並非平行，藉此可使由第一表面子區152a進入支持主體110a的光線因傾斜之第一光再導向結構142a的反射而變更行進方向，進而由第一側子區172a離開支持主體110a。此外，舉例而言，第一子部120a與第二子部130a的結合可使支持主體110a整體的剖面呈長方形，即支持主體110a的外表面不需要對應反射面角度調整，藉此可使支持主體110a具有較大面積的第一支撐表面150a。 There is a first interface 140a between the first sub-portion 120a and the second sub-portion 130a. The first interface 140a has a first light redirecting structure 142a. The first interface 140a may be a flat surface or may be an arc surface, such as a concave arc surface or a convex arc surface. In some examples, the first light redirecting structure 142a may be a reflective material layer (such as a metal layer) or a microstructure layer with a reflective effect. The first light redirecting structure 142a can change the direction of the light entering the supporting body 110a from the first surface sub-region 152a of the first supporting surface 150a, so that the light turns away from the supporting body 110a from the first side sub-region 172a of the side surface 170a . In the embodiment shown in FIG. 1, the cross section of the second sub-portion 130a is triangular, and the first sub-portion 120a is looped around the second sub-portion 130a. Therefore, the first interface 140a and the first support surface 150a between the first sub-portion 120a and the second sub-portion 130a are not parallel, so that the light entering the support body 110a from the first surface sub-region 152a can be inclined The reflection of a light redirecting structure 142a changes the traveling direction, and then leaves the supporting body 110a from the first side sub-region 172a. In addition, for example, the combination of the first sub-portion 120a and the second sub-portion 130a can make the entire cross section of the support body 110a rectangular, that is, the outer surface of the support body 110a does not need to be adjusted corresponding to the angle of the reflecting surface, thereby making it possible to support The main body 110a has a first supporting surface 150a with a larger area.

利用透明之第一子部120a與第二子部130a的搭配，可增加支持結構100a的有效支撐面積，並可減少無效的反射區域。此外，支持結構100a整體之剖面可為長方形，因此在太陽能模組封裝時，有利於支持結構100a和周邊的封裝材與光伏電池片匹配。在一些例子中，支持主體110a之第一支撐表面150a的面積可與第二支撐表面160a的面積相同或不同。在支持主體110a之第一支撐表面150a的面積不同於第二支撐表面160a時，支持結構100a整體之剖面可為非長方形，例如可為梯形。 By using the combination of the transparent first sub-portion 120a and the second sub-portion 130a, the effective supporting area of the supporting structure 100a can be increased, and the ineffective reflection area can be reduced. In addition, the overall cross-section of the support structure 100a may be rectangular. Therefore, when the solar module is packaged, it is beneficial to match the support structure 100a and the surrounding packaging materials with the photovoltaic cell sheet. In some examples, the area of the first supporting surface 150a of the supporting body 110a may be the same as or different from the area of the second supporting surface 160a. When the area of the first supporting surface 150a of the supporting body 110a is different from the second supporting surface 160a, the cross section of the entire supporting structure 100a may be non-rectangular, for example, may be trapezoidal.

支持結構100a可應用於太陽能模組中。請參照圖2，其係繪示依照本發明之一實施方式的一種太陽能模組的局部剖面示意圖。在此實施方式中，太陽能模組200a可為單面受光模組。太陽能模組200a主要可包含上板210、下板220、封裝材230、太陽能發電材240、以及支持結構100a。上板210設置於下板220之上方，且上板210之上板內表面212與下板220之下板內表面222彼此相對。舉例而言，上板210可與下板220大致平行。在圖2所示之實施方式中，上板210為透明，下板220可為透明或不透明。舉例而言，上板210可為玻璃，下板220可為玻璃或背板。 The support structure 100a can be applied to a solar module. Please refer to FIG. 2, which is a schematic partial cross-sectional view of a solar module according to an embodiment of the present invention. In this embodiment, the solar module 200a may be a single-sided light-receiving module. The solar module 200a may mainly include an upper plate 210, a lower plate 220, a packaging material 230, a solar power generation material 240, and a supporting structure 100a. The upper plate 210 is disposed above the lower plate 220, and the upper plate inner surface 212 of the upper plate 210 and the lower plate inner surface 222 of the lower plate 220 are opposite to each other. For example, the upper plate 210 may be substantially parallel to the lower plate 220. In the embodiment shown in FIG. 2, the upper plate 210 is transparent, and the lower plate 220 may be transparent or opaque. For example, the upper plate 210 may be glass, and the lower plate 220 may be glass or a back plate.

封裝材230設於上板210與下板220之間。舉例而言，封裝材230之材料可為聚乙烯醋酸乙烯酯。太陽能發電材240可包含數個光伏電池片，例如第一光伏電池片242與第二光伏電池片242。太陽能發電材240亦設於上板210與下板220之間，且被封裝材230所包覆。太陽能發電材240 之第一光伏電池片242與第二光伏電池片242相鄰水平設置。支持結構100a介於上板210與下板220之間，且設置在第一光伏電池片240與第二光伏電池片242之間，也為封裝材230所包覆。支持結構100a之架構、材質、與形狀已在上述實施方式中說明，於此不再贅述。 The packaging material 230 is provided between the upper plate 210 and the lower plate 220. For example, the material of the packaging material 230 may be polyethylene vinyl acetate. The solar power material 240 may include several photovoltaic cells, for example, the first photovoltaic cell 242 and the second photovoltaic cell 242. The solar power material 240 is also disposed between the upper plate 210 and the lower plate 220 and is covered by the packaging material 230. Solar power material 240 The first photovoltaic cell 242 and the second photovoltaic cell 242 are arranged horizontally adjacent to each other. The supporting structure 100a is interposed between the upper plate 210 and the lower plate 220, and is disposed between the first photovoltaic cell 240 and the second photovoltaic cell 242, and is also covered by the packaging material 230. The structure, material, and shape of the support structure 100a have been described in the above embodiments, and will not be repeated here.

支持結構100a之第一支撐表面150a可抵接上板210之上板內表面212，第二支撐表面160a則可抵接下板220之下板內表面222。藉此，支持結構100a可對上板210及下板220提供大於封裝材230的支撐力。在上板210為透明的例子中，由於支持主體110a之第一子部120a可透光，且第一介面140a呈傾斜，因此光線通過上板210且由第一支撐表面150a之第一表面子區152a進入支持主體110a而射向第一介面140a時，傾斜之第一介面140a的第一光再導向結構142a可變更光線之行進方向，使光線由側面170a之第一側子區172a離開支持主體110a，光線離開支持主體110a後至少有部分到達側面170a二側之太陽能發電材240的第一光伏電池片242與第二光伏電池片244。此外，支持主體110a係由可透光之第一子部120a與第二子部130a所構成，因此可使支持主體110a具有較大的第一支撐表面150a，而可提供較大的有效支撐面積。 The first support surface 150a of the support structure 100a can abut the upper surface 210 of the upper plate 210, and the second support surface 160a can abut the lower surface 220 of the lower plate 220. Thereby, the supporting structure 100a can provide the upper plate 210 and the lower plate 220 with a greater supporting force than the packaging material 230. In the example where the upper plate 210 is transparent, since the first sub-portion 120a of the supporting body 110a can transmit light and the first interface 140a is inclined, the light passes through the upper plate 210 and is passed by the first surface of the first support surface 150a When the area 152a enters the support body 110a and hits the first interface 140a, the first light redirecting structure 142a of the inclined first interface 140a can change the traveling direction of the light, so that the light leaves the support from the first side sub-region 172a of the side surface 170a After the main body 110a leaves the supporting main body 110a, at least part of it reaches the first photovoltaic cell 242 and the second photovoltaic cell 244 of the solar power generation material 240 on both sides of the side 170a. In addition, the supporting body 110a is composed of a light-transmissive first sub-portion 120a and a second sub-portion 130a, so that the supporting body 110a can have a larger first supporting surface 150a and can provide a larger effective supporting area .

請參照圖3，其係繪示依照本發明之一實施方式的一種太陽能模組的局部剖面示意圖。太陽能模組200b之架構大致與上述太陽能模組200a之架構類似，二者之間的差異在於太陽能模組200b之支持結構100b不同於太陽能 模組200a之支持結構100a。支持結構100b主要包含支持主體110b。支持主體110b具有彼此相對且可大致平行的第一支撐表面150b與第二支撐表面160b、以及連接於第一支撐表面150b與第二支撐表面160b之間的側面170b。第一支撐表面150b的面積可與第二支撐表面160b的面積相同或不同。第一支撐表面150b具有第一表面子區152b，側面170b具有第一側子區172b。 Please refer to FIG. 3, which is a schematic partial cross-sectional view of a solar module according to an embodiment of the present invention. The structure of the solar module 200b is roughly similar to the structure of the solar module 200a described above. The difference between the two is that the support structure 100b of the solar module 200b is different from solar energy. The supporting structure 100a of the module 200a. The supporting structure 100b mainly includes a supporting body 110b. The supporting body 110b has a first supporting surface 150b and a second supporting surface 160b that are opposite to each other and may be substantially parallel, and a side surface 170b connected between the first supporting surface 150b and the second supporting surface 160b. The area of the first support surface 150b may be the same as or different from the area of the second support surface 160b. The first support surface 150b has a first surface sub-region 152b, and the side 170b has a first side sub-region 172b.

支持主體110b可包含彼此連接之第一子部120b與第二子部130b，其中第一子部120b和第一表面子區152b及第一側子區172b鄰接。第一子部120b與第二子部130b之間具有第一介面140b，此第一介面140b具有第一光再導向結構142b。第一子部120b、第二子部130b、與第一介面140b之材質與功能可分別類似第一子部120a、第二子部130a、與第一介面140a，於此不再贅述。 The supporting body 110b may include a first sub-portion 120b and a second sub-portion 130b connected to each other, wherein the first sub-portion 120b is adjacent to the first surface sub-region 152b and the first side sub-region 172b. There is a first interface 140b between the first sub-portion 120b and the second sub-portion 130b. The first interface 140b has a first light redirecting structure 142b. The materials and functions of the first sub-portion 120b, the second sub-portion 130b, and the first interface 140b may be similar to the first sub-portion 120a, the second sub-portion 130a, and the first interface 140a, respectively, and will not be repeated here.

在圖3所示之實施例中，第二子部130b之剖面呈類火箭狀，第一子部120b則僅環設於第二子部130b上部的三角形上。因此，介於第一子部120b與第二子部130b之間的第一介面140b與第一支撐表面150b並非平行，且第一介面140b自第一支撐表面150b延伸至第二子部130b側邊的靠近中央區域處，藉此第一介面140b之第一光再導向結構142b可反射從第一表面子區152b進入支持主體110b的光線而使光線由第一側子區172b之上半部離開支持主體110b。亦即，相較於支持結構100a，被反射之光線到達太陽能發電材240正面的比率可獲得提高。前述第二子部130b 側邊的靠近中央區域處可依周圍第一光伏電池片242與第二光伏電池片244的位置而調整決定。舉例而言，太陽能發電材240具有面向上板210之上板內表面212的上發電材表面240a及面向下板220之下板內表面222的下發電材表面240b，經支持結構100b變更方向而到達太陽能發電材240的光線中，到達上發電材表面240a的光量大於到達下發電材表面240b的光量。此外，第一子部120b與第二子部130b的結合可使支持主體110b整體的剖面呈長方形，藉此支持主體110b可具有較大的第一支撐表面150b。 In the embodiment shown in FIG. 3, the cross section of the second sub-portion 130b is rocket-like, and the first sub-portion 120b is only looped on the triangle above the second sub-portion 130b. Therefore, the first interface 140b and the first support surface 150b between the first sub-portion 120b and the second sub-portion 130b are not parallel, and the first interface 140b extends from the first support surface 150b to the second sub-portion 130b side Near the central area, whereby the first light redirecting structure 142b of the first interface 140b can reflect the light entering the supporting body 110b from the first surface sub-region 152b, so that the light passes from the upper half of the first side sub-region 172b Leave the support body 110b. That is, the ratio of the reflected light reaching the front surface of the solar power generation material 240 can be improved compared to the support structure 100a. The aforementioned second sub-section 130b The side near the central area can be adjusted according to the positions of the surrounding first photovoltaic cells 242 and second photovoltaic cells 244. For example, the solar power generation material 240 has an upper power generation material surface 240a facing the upper inner surface 212 of the upper plate 210 and a lower power generation material surface 240b facing the lower inner surface 222 of the lower plate 220, and the direction is changed by the support structure 100b. Of the light reaching the solar power generation material 240, the amount of light reaching the upper power generation material surface 240a is greater than the amount of light reaching the lower power generation material surface 240b. In addition, the combination of the first sub-portion 120b and the second sub-portion 130b can make the entire cross section of the support body 110b rectangular, so that the support body 110b can have a larger first support surface 150b.

請參照圖4，其係繪示依照本發明之一實施方式的一種太陽能模組的局部剖面示意圖。太陽能模組200c可為雙面受光模組。太陽能模組200c之架構大致可與上述太陽能模組200a之架構類似，二者之間的差異在於太陽能模組200c之支持結構100c不同於太陽能模組200a之支持結構100a，且上板210與下板220均為透明。支持結構100c主要包含支持主體110c。支持主體110c具有彼此相對且可大致平行的第一支撐表面150c與第二支撐表面160c、以及連接於第一支撐表面150c與第二支撐表面160c之間的側面170c。第一支撐表面150c的面積可與第二支撐表面160c的面積相同或不同。第一支撐表面150c具有第一表面子區152c，第二支撐表面160c具有第二表面子區162c，側面170c具有第一側子區172c與第二側子區174c。 Please refer to FIG. 4, which is a schematic partial cross-sectional view of a solar module according to an embodiment of the present invention. The solar module 200c may be a double-sided light-receiving module. The structure of the solar module 200c can be roughly similar to the structure of the solar module 200a described above. The difference between the two is that the support structure 100c of the solar module 200c is different from the support structure 100a of the solar module 200a, and the upper plate 210 and the lower The boards 220 are all transparent. The supporting structure 100c mainly includes a supporting body 110c. The supporting body 110c has a first support surface 150c and a second support surface 160c that are opposite to each other and may be substantially parallel, and a side surface 170c connected between the first support surface 150c and the second support surface 160c. The area of the first support surface 150c may be the same as or different from the area of the second support surface 160c. The first support surface 150c has a first surface sub-region 152c, the second support surface 160c has a second surface sub-region 162c, and the side surface 170c has a first side sub-region 172c and a second side sub-region 174c.

支持主體110c可包含第一子部120c、第二子部130c、與第三子部180c，其中第一子部120c及第三子部 180c分別與第二子部130c相連。第一子部120c和第一表面子區152c及第一側子區172c鄰接，而第三子部180c為透明且和第二表面子區162c及第二側子區174c鄰接。第一子部120c與第二子部130c之間具有第一介面140c，第一介面140c具有第一光再導向結構142c。第三子部180c與第二子部130c之間具有第二介面190c，第二介面190c具有第二光再導向結構192c。第一子部120c及第三子部180c、第二子部130c、與第一介面140c及第二介面190c之材質與功能可分別類似第一子部120a、第二子部130a、與第一介面140a。 The supporting body 110c may include a first sub-portion 120c, a second sub-portion 130c, and a third sub-portion 180c, wherein the first sub-portion 120c and the third sub-portion 180c are respectively connected to the second sub-portions 130c. The first sub-portion 120c is adjacent to the first surface sub-region 152c and the first side sub-region 172c, and the third sub-portion 180c is transparent and adjacent to the second surface sub-region 162c and the second side sub-region 174c. There is a first interface 140c between the first sub-portion 120c and the second sub-portion 130c, and the first interface 140c has a first light redirecting structure 142c. There is a second interface 190c between the third sub-portion 180c and the second sub-portion 130c, and the second interface 190c has a second light redirecting structure 192c. The materials and functions of the first sub-portion 120c and the third sub-portion 180c, the second sub-portion 130c, the first interface 140c and the second interface 190c may be similar to the first sub-portion 120a, the second sub-portion 130a, and the first Interface 140a.

在圖4所示之實施例中，第二子部130c之剖面呈二梯形底邊對接的類菱形，第一子部120c僅環設於第二子部130c的上梯形的側面上，第二子部180c僅環設於第二子部130c的下梯形的側面上。因此，第一介面140c與第一支撐表面150c並非平行，第二介面190c與第二支撐表面160c並非平行，且第一介面140c與第二介面190c分別自第一支撐表面150c與第二支撐表面160c延伸至第二子部130c側邊的靠近中央區域處。藉此，第一介面140c之第一光再導向結構142c可反射通過上板210且從第一表面子區152c進入支持主體110c的光線而使光線由第一側子區172c離開支持主體110c，並使此光線至少有部分到達側面170c二側之太陽能發電材240的第一光伏電池片242與第二光伏電池片244。經第一光再導向結構142c變更方向而到達太陽能發電材240的光線中，到達上發電材表面240a的光量大於到達下發電材表面240b的光量。第二介面190c之第 二光再導向結構192c可反射通過下板220且從第二表面子區162c進入支持主體110c的光線而使光線由第二側子區174c離開支持主體110c。經第二光再導向結構192c變更方向而到達太陽能發電材240的光線中，到達下發電材表面240b的光量大於到達上發電材表面240a的光量。前述第二子部130c側邊的靠近中央區域處可依周圍第一光伏電池片242與第二光伏電池片244的位置而調整決定。 In the embodiment shown in FIG. 4, the cross section of the second sub-portion 130c is a diamond-like shape with two trapezoidal bottom edges butted, the first sub-portion 120c is only looped on the side of the upper trapezoid of the second sub-portion 130c, the second The sub-portion 180c is only looped on the side of the lower trapezoid of the second sub-portion 130c. Therefore, the first interface 140c and the first support surface 150c are not parallel, the second interface 190c and the second support surface 160c are not parallel, and the first interface 140c and the second interface 190c are respectively separated from the first support surface 150c and the second support surface 160c extends to the side of the second sub-portion 130c near the central area. Thereby, the first light redirecting structure 142c of the first interface 140c can reflect the light passing through the upper plate 210 and enter the support body 110c from the first surface sub-region 152c, so that the light leaves the support body 110c from the first side sub-region 172c, And at least part of this light reaches the first photovoltaic cell 242 and the second photovoltaic cell 244 of the solar power generation material 240 on both sides of the side 170c. Among the light rays reaching the solar power generation material 240 via the first light redirecting structure 142c, the amount of light reaching the upper power generation material surface 240a is greater than the amount of light reaching the lower power generation material surface 240b. The second interface 190c The two-light redirecting structure 192c can reflect the light passing through the lower plate 220 and entering the support body 110c from the second surface sub-region 162c, so that the light leaves the support body 110c from the second side sub-region 174c. Among the light rays reaching the solar power generation material 240 via the second light redirecting structure 192c, the amount of light reaching the lower power generation material surface 240b is greater than the amount of light reaching the upper power generation material surface 240a. The side of the second sub-portion 130c near the central area can be adjusted and determined according to the positions of the surrounding first photovoltaic cells 242 and second photovoltaic cells 244.

因此，支持結構100c之第一介面140c與第二介面190c可將從太陽能模組200c正面與背面入射的光線分別導向太陽能發電材240之上發電材表面240a與下發電材表面240b，以有效利用太陽能模組200c正面與背面的入射光。此外，第一子部120c、第二子部130c、與第三子部180c的結合可使支持主體110c整體的剖面呈長方形，藉此支持主體110c可具有較大的第一支撐表面150c與第二支撐表面160c。 Therefore, the first interface 140c and the second interface 190c of the support structure 100c can direct the light incident from the front and back of the solar module 200c to the upper and lower power generating material surfaces 240a and 240b of the solar power generating material 240 for effective use The incident light on the front and back of the solar module 200c. In addition, the combination of the first sub-portion 120c, the second sub-portion 130c, and the third sub-portion 180c can make the entire cross section of the support body 110c rectangular, so that the support body 110c can have larger first support surfaces 150c and Two support surface 160c.

請參照圖5，其係繪示依照本發明之一實施方式的一種太陽能模組的局部剖面示意圖。太陽能模組200d可為雙面受光模組。太陽能模組200d之架構大致可與上述太陽能模組200c之架構類似，二者之間的差異在於太陽能模組200d之支持結構100d與太陽能模組200c之支持結構100c略有差異。支持結構100d主要包含支持主體110d。支持主體110d具有彼此相對且可大致平行的第一支撐表面150d與第二支撐表面160d、以及連接於第一支撐表面150d與第二支撐表面160d之間的側面170d。第一支撐表面150d 的面積可與第二支撐表面160d的面積相同或不同。第一支撐表面150d具有第一表面子區152d，第二支撐表面160d具有第二表面子區162d，側面170d具有第一側子區172d與第二側子區174d。 Please refer to FIG. 5, which is a schematic partial cross-sectional view of a solar module according to an embodiment of the present invention. The solar module 200d may be a double-sided light-receiving module. The structure of the solar module 200d can be roughly similar to the structure of the solar module 200c described above. The difference between the two lies in the slight difference between the support structure 100d of the solar module 200d and the support structure 100c of the solar module 200c. The supporting structure 100d mainly includes a supporting body 110d. The supporting body 110d has a first support surface 150d and a second support surface 160d that are opposite to each other and may be substantially parallel, and a side surface 170d connected between the first support surface 150d and the second support surface 160d. First support surface 150d The area of may be the same as or different from the area of the second support surface 160d.

支持主體110d可包含第一子部120d、第二子部130d、與第三子部180d，其中第一子部120d及第三子部180d均與第二子部130d相連。第一子部120d和第一表面子區152d及第一側子區172d鄰接，而第三子部180d為透明且和第二表面子區162d及第二側子區174d鄰接。第一子部120d與第二子部130d之間具有第一介面140d，第一介面140d具有第一光再導向結構142d。第三子部180d與第二子部130d之間具有第二介面190d，第二介面190d具有第二光再導向結構192d。第一子部120d及第三子部180d、第二子部130d、與第一介面140d及第二介面190d之材質與功能可分別類似第一子部120c及第三子部180c、第二子部130c、與第一介面140c及第二介面190c。 The supporting body 110d may include a first sub-portion 120d, a second sub-portion 130d, and a third sub-portion 180d, wherein the first sub-portion 120d and the third sub-portion 180d are both connected to the second sub-portion 130d. The first sub-portion 120d is adjacent to the first surface sub-region 152d and the first side sub-region 172d, and the third sub-portion 180d is transparent and adjacent to the second surface sub-region 162d and the second side sub-region 174d. There is a first interface 140d between the first sub-portion 120d and the second sub-portion 130d, and the first interface 140d has a first light redirecting structure 142d. There is a second interface 190d between the third sub-portion 180d and the second sub-portion 130d, and the second interface 190d has a second light redirecting structure 192d. The materials and functions of the first sub-portion 120d and the third sub-portion 180d, the second sub-portion 130d, the first interface 140d and the second interface 190d may be similar to the first sub-portion 120c and the third sub-portion 180c, the second sub-portion The portion 130c, the first interface 140c and the second interface 190c.

Therefore, the first interface 140d and the first supporting surface 150d are not parallel, and the second interface 190d and the second supporting surface 160d are not parallel. The first interface 140d extends from the first support surface 150d to the upper portion of the side surface 170d of the supporting body 110d. The second interface 190d extends from the second support surface 160d to the lower portion of the side surface 170d of the supporting body 110d. The side of the aforementioned supporting body 110d The upper and lower ranges of 170d can be adjusted and determined according to the positions of the surrounding first photovoltaic cells 242 and second photovoltaic cells 244. In addition, the first interface 140d may be higher than the upper power generating material surface 240a of the solar power generating material 240, and the second interface 190d may be lower than the lower power generating material surface 240b. Thereby, the ratio of the light reaching the upper power generating material surface 240a by changing the direction of the first light redirecting structure 142d and the light reaching the lower power generating material surface 240b by changing the direction of the second light redirecting structure 192d can be increased.

The supporting body 110e2 may include a first sub-portion 120e2 and a second sub-portion 130e2 connected to each other, wherein the first sub-portion 120e2 and The first surface sub-region 152e2 and the first side sub-region 172e2 are adjacent to each other. There is a first interface 140e2 between the first sub-portion 120e2 and the second sub-portion 130e2. The first interface 140e2 has a first light redirecting structure 142e2. The materials and functions of the first sub-portion 120e2, the second sub-portion 130e2, and the first interface 140e2 may be similar to the first sub-portion 120a, the second sub-portion 130a, and the first interface 140a, respectively.

光線經由第一支撐表面150e2之第一表面子區152e2進入支持主體110e2而射向第一介面140e2時，傾斜之第一介面140e2的第一光再導向結構142e2可變更光線之行進方向，使光線由側面170e2之第一側子區172e2離開支持主體110e2，光線離開支持主體110e2後至少有部分到達四周之太陽能發電材240。因此，在太陽能模組200e之不同區域的支持結構100e1與100e2可在具有大致相同之支撐強度下提供所需之反射方向，即支持結構100e1與100e2具有不同之光再導向方向。 When the light enters the supporting body 110e2 through the first surface sub-region 152e2 of the first supporting surface 150e2 and hits the first interface 140e2, the first light redirecting structure 142e2 of the inclined first interface 140e2 can change the traveling direction of the light, so that the light The first side sub-region 172e2 of the side surface 170e2 leaves the supporting body 110e2. After the light leaves the supporting body 110e2, at least part of it reaches the surrounding solar power material 240. Therefore, the support structures 100e1 and 100e2 in different regions of the solar module 200e can provide a desired reflection direction under substantially the same support strength, that is, the support structures 100e1 and 100e2 have different light redirecting directions.

第一光再導向結構142g與第二光再導向結構192g在支持結構100g之厚度方向上的位置可調整。舉例而言，第一光再導向結構142g與第二光再導向結構192g可位於太陽能發電材240之上發電材表面240a與下發電材表面240b之間，或者第一光再導向結構142g與第二光再導向結構192g可分別高於上發電材表面240a與低於下發電材表面240b。第一光再導向結構142g可反射從第一表面子區152g進入支持主體110g的光線而使光線由第一側子區172g離開支持主體110g。經第一光再導向結構142g變更方向而到達太陽能發電材240的光線中，到達上發電材表面240a的光量大於到達下發電材表面240b的光量。第二光再導向結構192g可反射從第二表面子區162g進入支持主體110g的光線而使光線由第二側子區174g離開支持主體110g。經第二光再導向結構192g變更方向而到達太陽能發電材240的光線中，到達下發電材表面240b的光量大於到達上發電材表面240a的光量。 The positions of the first light redirecting structure 142g and the second light redirecting structure 192g in the thickness direction of the supporting structure 100g can be adjusted. For example, the first light redirecting structure 142g and the second light redirecting structure 192g may be located between the power generating material surface 240a and the lower power generating material surface 240b of the solar power generating material 240, or the first light redirecting structure 142g and the first The two light redirecting structures 192g may be respectively higher than the upper power generating material surface 240a and lower than the lower power generating material surface 240b. The first light redirecting structure 142g can reflect the light entering the support body 110g from the first surface sub-region 152g so that the light leaves the support body 110g from the first side sub-region 172g. Among the light rays reaching the solar power generation material 240 via the first light redirecting structure 142g, the amount of light reaching the upper power generation material surface 240a is greater than the amount of light reaching the lower power generation material surface 240b. The second light redirecting structure 192g can reflect the light entering the support body 110g from the second surface sub-region 162g so that the light leaves the support body 110g from the second side sub-region 174g. Among the light rays reaching the solar power generation material 240 via the second light redirecting structure 192g, the amount of light reaching the lower power generation material surface 240b is greater than the amount of light reaching the upper power generation material surface 240a.
