Angular transmission characterization of CPV modules based on CCD measurements

Abstract

A cost effective method to obtain the two-dimensional angular transmission function of a concentrator photovoltaic (CPV) system is presented. For this purpose, we take advantage of a large area collimator mirror and the forward biased receiver cell itself to reproduce a Lambertian beam by electroluminescence. To validate this method, angular transmission functions of several CPV system technologies have been measured with direct illumination (flash CPV simulator and Sun light) and the "luminescence inverse method". © 2010 American Institute of Physics.
