Impact of the temperature dependence of CPV optics transmittance on the current mismatch of multi-junction solar cells

Abstract

The influence of spectra and temperature dependence of concentrator photovoltaics (CPV) optics is investigated by modelling yearly series of ambient conditions, such as typical meteorological year (TMY) data, and simulating the response of relevant CPV technologies. Results show the influence the optics have on the effective spectra available at the solar cell level. This allows us to find the limiting factors of a CPV module performance and permits energy yield predictions.
