Abstract:

Based on the electroluminescent method and the two-diode equivalent circuit model of a solar cell, the current-voltage characteristics of wide-bandgap subcells in the structure with the corresponding parameters of saturation dark  currents are obtained. In addition, the approach has been tested on samples exposed to various radiation doses, which made it possible to determine the degradation rate of the photovoltaic characteristics of solar cells.
