Compatibility of Fresnel Lenses and Photovoltaic Cells in Concentrator Modules

摘要

Test data are used to compare, for point focus photovoltaic concentrator modules, the relationship between Fresnel lens and module efficiency. The data shows that lenses designed for maximum optical efficiency may not produce the maximum module efficiency. Lenses designed with consideration for the photon flux distribution on the solar cell may improve module efficiency possibly at some loss in lens optical performance. (ERA citation 06:021777)
