We have examined the performance of a see-through photovoltaics module that uses a low-concentration prism concentrator by undertaking ray-tracing analysis and an on-site experiment. The incident angle dependency of the prism concentrator makes it possible to concentrate direct solar radiation onto solar cells and transmit diffuse solar radiation. Fewer solar cells can then be used without sacrificing the conversion efficiency or lighting performance. The module generates approximately 1.15 more electricity than a conventional module while operating with 63% less solar cell area. We also introduce a design method for the concentrator geometry that adjusts the incident angle dependency for different latitude and tilt angles.
我们通过进行光线追踪分析和现场实验，研究了一种使用低浓度棱镜聚光器的透明光伏模块的性能。棱镜聚光器对入射角的依赖性使得将直射太阳辐射集中到太阳能电池上并透射散射太阳辐射成为可能。这样就可以使用更少的太阳能电池，而不牺牲转换效率或照明性能。该模块在太阳能电池面积减少63%的情况下运行时，产生的电力比传统模块多约1.15倍。我们还介绍了一种聚光器几何形状的设计方法，该方法可针对不同的纬度和倾斜角度调整入射角依赖性。
