Abstract

GaAs space solar cells always suffered from the complex and hostile space environment. Space solar cell reliability is crucial factor to ensure the normal operation of space satellites. A method of modeling the degradation of GaAs space solar cells is proposed here. The method is to find one crucial performance parameter to depict the degradation process. By applying compound Poisson process and general stress-strength interference model, the reliability of GaAs space solar cell can be calculated. According to the 15-years observation data of particle radiation, high-energy electron radiation experiment on the GaAs space solar cells was developed to verify the method. The method is more effective to assess the GaAs space solar cell reliability compared to the existing degradation mechanism modeling. And reliability can be calculated through the attenuation of output power which was easy to detect and record.
