Abstract: Proton/electron irradiation experiments are carried out for triple-junction solar cells. The radiation damage sensitive region in triple-junction solar cell is identified, and the degradation model of electrical characteristics with the displacement damage dose (DDD) is established. Based on TCAD simulations, the degradation mechanisms of triple-junction solar cells after irradiation is studied and verified. Combined with Monte Carlo simulations and ground irradiation tests, the equivalent DDD method is used to predict the on-orbit performances of triple-junction solar cells. The on-orbit degradations of typical Chinese triple-junction solar cells in GEO and LEO orbits are calculated.
