The precise calibration and reliability verification of aerospace-grade multi-junction laminated batteries, space photovoltaic components, and spacecraft solar wing systems have long faced industry pain points such as insufficient adaptability of fixed spectral simulators and inability to control spectral energy. Traditional AM0 simulators have fixed spectral ratios and cannot simulate the spectral energy attenuation and spectral shift characteristics under complex space conditions, making it difficult to meet the independent response testing requirements of tri-junction and quad-junction gallium arsenide laminated batteries. A single fixed spectral test is prone to problems such as sub-battery electrical mismatch, parameter calibration deviation, and performance prediction distortion, which cannot support the precise performance evaluation of space batteries during the initial BOL lifespan and the end EOL lifespan, severely restricting the research and development of new processes for space photovoltaic devices, in-orbit reliability verification, and batch quality control.
