However, since the light transmittance of the solar wafer is low, and the light transmittance of the entire power generation glass is reduced, the practical application to the window causes visual obstruction and the disadvantage of poor indoor lighting.

The first end 114 is opposite the second end 113. The microstructures 12 are recessed from the first surface 111 to the substrate body portion 11.
在本實施例中，該等微結構12位於該第一表面111，且從該第一表面111向該第二表面112延伸。該等微結構12之俯視面係為橢圓形，且係利用例如雷射加工而成，而該等微結構12的開口形狀並不侷限橢圓形，亦可以其他製程方式而形成各種形狀，例如：圓形、方形、多角形。該等微 結構12係彼此不連接，也就是該等微結構12於第一表面111之開口邊緣係彼此不連接，且該等微結構12係可為不連續分佈。該等微結構12彼此間之距離係不全為相等，亦即，該等微結構12於第一表面111之開口邊緣之間距係不相等。該等微結構12之分佈密度亦可非全為均一。此外，各該等微結構12具一開口寬度，該些開口寬度係可全為均一或非全為均一。 In the present embodiment, the microstructures 12 are located on the first surface 111 and extend from the first surface 111 toward the second surface 112. The top surface of the microstructures 12 is elliptical and is processed by, for example, laser processing. The shape of the openings of the microstructures 12 is not limited to an elliptical shape, and various shapes can be formed by other processes, for example: Round, square, polygonal. The micro The structures 12 are not connected to each other, that is, the microstructures 12 are not connected to each other at the opening edges of the first surface 111, and the microstructures 12 may be discontinuously distributed. The distances between the microstructures 12 are not all equal, that is, the distances between the microstructures 12 at the edge of the opening of the first surface 111 are not equal.

At the same time, the distance d 1 between the microstructures 12 adjacent to the second end 113 is smaller than the distance d 2 between the microstructures 12 adjacent to the first end 114. That is, the density of the microstructures 12 adjacent the first end 114 to the microstructures 12 adjacent the second end 113 is gradually increased from small to small.

Preferably, the microstructures 12 direct a portion of the incident light 16 to the photoelectric conversion element 14 to convert a portion of the energy of the incident light 16 into electrical energy, while the other portion of the incident light 16 is directly The light guide substrate 10 is penetrated. Therefore, when the light-guiding power generation module 1 is actually applied to a window, it is less likely to cause visual obstruction, and it is also less likely to affect indoor lighting. That is, it is possible to achieve both light penetration and power generation.

參考圖17，顯示微結構密度同樣為19.5%但是分佈型態不同之導光基板之測試結果曲線圖。其中，▲代表微結構均勻分佈之導光基板10(圖9)在不同入射角度之入射光照射下該等感測器所量測到的電流值(此曲線與圖16相同)，◆代表微結構分佈型態為圖2之導光基板10(靠近該第一端114之微結構12之密度至靠近該第二端113之微結構12之密度係為由小逐漸變大)在不同入射角度之入射光照射下該等感測器所量測到的電流值，■代表微結構分佈型態為圖12之導光基板10(靠近該第一端114之微結構12之密度與靠近該第二端113之微結構之密度係相等，且小於位於該中央部33之微結構12之密度)在不同入射角度之入射光照射下該等感測器所量測到的電流值，●代表微結構分佈型態為圖11之導光基板10(靠近該第一端114之微結構12之密度與靠近該第二端113之微結構之密度係相等，且大於位於該中央部33之微結構12之密度)在不同入射角度之入射光照射下該等感測器所量測到的電流值。由圖中可看出，微結構密度同樣為19.5%，但是微結構分佈型態不同之導光基板，在該等感測器量測到的電流值幾乎差異不大。可見 微結構分佈型態影響該導光基板10之導光效能較小。 Referring to Fig. 17, a test result graph showing a light guide substrate having a microstructure density of 19.5% but a different distribution pattern is shown. Wherein, ▲ represents the current value measured by the sensors of the light guide substrate 10 (Fig. 9) with uniform microstructure distribution under the incident light of different incident angles (this curve is the same as Fig. 16), ◆ represents micro The structure distribution pattern is the light guiding substrate 10 of FIG. 2 (the density of the microstructures 12 close to the first end 114 to the microstructure 12 close to the second end 113 is gradually increased from small to large) at different incident angles. The current value measured by the sensors under the illumination of the incident light, ■ represents the microstructure distribution pattern of the light guide substrate 10 of FIG. 12 (the density of the microstructure 12 near the first end 114 is close to the first The density of the microstructures of the two ends 113 are equal and smaller than the density of the microstructures 12 located at the central portion 33. The current values measured by the sensors under different incident angles of incident light, ● represents micro The structure distribution pattern is the light guiding substrate 10 of FIG. 11 (the density of the microstructures 12 close to the first end 114 is equal to the density of the microstructures close to the second end 113, and is larger than the microstructure located at the central portion 33. 12 density) measured by the sensors under different incident angles of incident light The current value. As can be seen from the figure, the microstructure density is also 19.5%, but the light guide substrates with different microstructure distribution patterns have little difference in the current values measured by the sensors. visible The microstructure distribution pattern affects the light guiding performance of the light guiding substrate 10 to be small.
參考圖18，顯示在不同入射角度之入射光照射下，不同微結構密度之導光基板之光學模擬結果曲線圖。其中，●代表入射光之入射角度θ為80度，■代表入射光之入射角度θ為70度，▲代表入射光之入射角度θ為60度，×代表入射光之入射角度θ為50度，＊代表入射光之入射角度θ為40度。此外，縱座標導光效率係表示入射光能量與該等感測器可量測到的能量之比值。由圖中可看出，微結構密度會影響導光效率，且在微結構密度為15%至50%(較佳為20%至40%)時有良好的導光效率，尤其是高入射角度(例如70度或80度)。 Referring to Fig. 18, there is shown a graph of optical simulation results of light guide substrates of different microstructure densities under illumination of incident light at different incident angles. Wherein, ● the incident angle θ representing the incident light is 80 degrees, ■ the incident angle θ representing the incident light is 70 degrees, ▲ represents the incident angle θ of the incident light is 60 degrees, and × represents the incident angle θ of the incident light is 50 degrees. * The incident angle θ representing the incident light is 40 degrees. In addition, the ordinate light guiding efficiency is the ratio of the incident light energy to the energy measurable by the sensors. As can be seen from the figure, the microstructure density affects the light guiding efficiency, and has a good light guiding efficiency at a microstructure density of 15% to 50% (preferably 20% to 40%), especially a high incident angle. (eg 70 degrees or 80 degrees).
