A prototype concentrator photovoltaic (CPV) module with high solar concentration, an added low-cost solar cell, and an adjoining multi-junction solar cell is fabricated and experimentally demonstrated. In the present CPV module, the low cost solar cell captures diffuse solar radiation penetrating the concentrator lens and the multi-junction cell captures concentrated direct solar radiation. On-sun test results show that the electricity generated by a Fresnel lens-based CPV module with an additional crystalline silicon solar cell is greater than that for a conventional CPV module by a factor of 1.44 when the mean ratio of diffuse normal irradiation to global normal irradiation at the module aperture is 0.4. Several fundamental optical characteristics are presented for the present module.
制造并通过实验展示了一种具有高太阳能聚光率的原型聚光光伏（CPV）模块，该模块添加了低成本太阳能电池以及相邻的多结太阳能电池。在当前的CPV模块中，低成本太阳能电池捕获穿透聚光透镜的漫射太阳辐射，而多结电池捕获集中的直射太阳辐射。实地测试结果表明，当模块孔径处的漫射法向辐照度与总法向辐照度的平均比值为0.4时，带有附加晶体硅太阳能电池的基于菲涅尔透镜的CPV模块产生的电量比传统CPV模块多1.44倍。文中给出了当前模块的几个基本光学特性。
