Abstract:

In the paper the simulation of the response of the working parameters of multijunction A{3}B{5} photoconverters with optical concentrators on the change in the spectral composition of the solar radiation in different climatic conditions has been performed. Energy production of the photoconverters in several geographical locations was estimated. It was shown that inaccuracy of prediction of the energy production might be up to 16 % high in the case of neglecting photoconverter efficiency changing under the incident light spectral composition variation.
