Abstract
Concentrator optical systems create non-uniform irradiance distributions over the solar cell. Multijunction solar cells efficiency is sensitive to those spatial and spectral non-uniformities. The first step to evaluate efficiency losses is to known irradiance distributions created by concentrator optics. In this paper results from raytracing simulations are presented. However, simulations represent too ideal optical behavior predicting huge irradiation peaks. Real measurements using a CCD camera and adequate filters have been carried out to obtain the irradiance peaks that will take place in reality. Results show how simulations predict `peak to average¿ values much higher than measured.
