Asymmetric Fresnel Lenses in CPV

摘要

The Fresnel lens is a popular solution for Concentrating Photovoltaic (CPV) designs, since it can significantly reduce optical material (e.g. cost). In this work, we investigate the use of asymmetric Fresnel lenses to shape the concentrated irradiance distribution which strikes a solar cell using a flux-tube approach in conjunction with XY polynomial surfaces. Asymmetric lens solutions at Cx = 1, Cx = 160x, and Cx = 314 are presented.
