Abstract

Highlights: Review of techniques to assess the efficiency of primary lenses for CPV. Methods to quantify the transmission losses. Methods to estimate the size and shape of the light spot. Example case showing the relevant information for a Fresnel lens. Abstract: This article summarizes experimental methods to evaluate the performance and to assess the efficiency of a lens that will be used as primary optics in a concentrating photovoltaic system comprising multijunction solar cells. The methods are classified into two groups: those intended to quantify the transmission losses and those that estimate the size and shape of the light spot. In addition, the optical efficiency definition is reviewed and a systematic procedure to evaluate it is proposed.
