The displacement damage dose (DDD) for space solar cell is greatly affected by the displacement threshold energy (Ed) during degradation by irradiation with low-energy electrons. In the proposed study, the unpredictable degradation of AlInGaP solar cells in the present DDD model is observed. The findings suggest that the predicted degradation during exposure to low-energy electrons may differ from the actual value. However, it is clarified that if the Ed value is rederived, the nonionizing energy loss can indicate the induced-defect rates in the AlInGaP under irradiation with electrons with a wide range of energy.
