To improve the efficiency of bifacial photovoltaic modules, the idea of light deflection was addressed. A thin film with an intended structure was applied in the space between the cells. Due to the selected structural geometry, unused light is specifically redirected to the solar cell and can be absorbed by it and converted into additional current. The effect of the light-directing film was both simulated and measured. Single PV modules without and with commercial structured films or white back sheet were measured to evaluate the results The expected gain of up to 11% from the simulation could not be achieved by measurement, by reaching about 3%.

双面光伏组件导光膜

为了提高双面光伏模块的效率，解决了光偏转的想法。在电池之间的空间中应用具有预期结构的薄膜。由于选定的结构几何形状，未使用的光被专门重定向到太阳能电池，并可以被它吸收并转换为额外的电流。对光导向膜的效果进行了模拟和测量。测量了没有和有商业结构膜或白色背板的单个 PV 模块以评估结果。通过测量无法实现模拟中高达 11% 的预期增益，达到约 3%。
