Modeling of the degradation of III–V triple-junction cells due to particle irradiation on the basis of component cells

The paper reports about the possibility of predicting the degradation of III-V multi-junction solar cells due to particle irradiation in space solely based on the radiation response of the respective sub cells. State-of-the art triple-junction solar cells of the 3G28 class manufactured by AZUR Space GmbH are used as an example to demonstrate how to model the degradation behavior of multi-junction cell from the degradation behavior of the respective component cells, as investigated in this study. The advantages of component cells for understanding and modeling the behavior of multi-junction cells under different conditions are discussed.
