A method for studying individual subcells in a multi-junction solar cell is considered. Single- and double-junction solar cells with operating junctions corresponding to those of a triple-junction solar cell with a GaInP/GaAs/Ge structure grown by the MOCVD method have been obtained. The current-voltage characteristics, as well as the spectral characteristics of the external quantum efficiency, were measured. It was found that the spectral sensitivity of the GaAs junction for a two-junction solar cell in the shortwave region is higher than for a three-junction solar cell. The phenomenon revealed as a result of the analysis of the obtained data requires further investigation.
Keywords:
