Titel
Spectrometric outdoor characterization of CPV modules using isotype monitor cells
Abstract
In this paper we present a method to investigate the impact of the solar spectrum on the output parameters of a CPV module equipped with triple-junction solar cells. The changes of the sunĀ“s spectrum were monitored by using calibrated isotype solar cells. A correlation of the CPV module outdoor performance to changes in the sun spectrum has been determined. Experimental results of the spectral impact on the current of a Daido Steel CPV module are presented. Finally, a correction method is applied in order to derive the module's current under reference spectral conditions.
