Study for Decay Trend of the Solar Cell under Varied Radiation Dose

Any parts and equipment used on satellites, including solar products, need to pass more stringent certification and testing standards than those on the surface. The low temperature and high radiation environment in space are very likely to have an adverse effect on electronic components, so testing the reliability of electronic components under low temperature conditions and their resistance to radiation is an important issue. In addition, the sources of space radiation include cosmic rays, solar flares and radiation belts. These sources contain various high-energy particles such as protons, electrons and heavy ions, which can cause degradation of satellite electronic components and temporary or permanent functional abnormalities. Therefore, before electronic components perform space missions, the impact of radiation needs to be evaluated on the ground. Damage to satellites from space radiation is inevitable, but it can be reduced through mitigation measures. The simplest method is shielding, but this will increase the satellite's payload weight and will not be effective in generating electricity for solar panels. Therefore, in this study, we use different ARC coating materials and consider the design of multi-layer anti-reflection layers to reduce the net charge accumulation at the interface so that it can be used in space environments. In addition, considering the subsequent module packaging method, it is also necessary to design the electrode pattern and the parameters that optimize the resistance to different radiation doses.
