A novel method for rapid design and evaluation of photovoltaic concentrators

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

The electrical output of low concentration systems with standard pv cells is heavily impaired by non uniform irradiation distribution on the cells. In order to design new concentrators that improve the system efficiency by homogenizing the light, a new method of evaluation has been developed. It is based on simulations, and generates an estimated annual output. The method consists of three steps, optical simulation of the concentrator, electrical simulations of the cells in the concentrator at a certain solar angle of incidence, and system simulations of the annual output. As an example, the method is used in the design of a stationary wall concentrator.
