Abstract

A distributed model of an AlGaAs/GaAs solar cell is coupled to a ray trace model of a curved groove fresnel lens to predict cell performance under sunlight concentrated by such a lens. The values of the equivalent circuit elements in the model are obtained experimentally by a novel flash test technique. Predictions compare closely to experiment, and it is found that contact grid series resistance plays an important role in performance.
