摘　　要：分析空间辐射效应对三结砷化镓(TJ-GaAs)太阳电池阵的影响,结合地面试验结果对太阳电池阵进行抗辐射设计,并在某倾斜地球同步轨道(IGSO)卫星上进行验证。通过对在轨卫星5 a的遥测数据分析,得出太阳电池阵输出功率因辐射效应造成的衰减规律,最后与设计方案进行比较,有效验证了抗辐射设计的数学模型,可为其他中高轨道卫星太阳电池阵的设计提供参考。Based on the theoretically analysis of the space radiation effect on triple-junction galliumar senide(TJ-GaAs)solar cells,combined with the results of ground test results,the radiation shielding design of the space solar cell array is presented this paper.This design has been successfully applied to one satellite operating in inclined geosynchronous orbit(IGSO)and the on-orbit verification has been obtained.The natural attenuation law of solar cell array output power caused by radiation effects is calculated through the data analysis of satellite measured telemetry parameters covering 5 year life cycle.Compared with the ground design results,the accuracy of the mathematical model and the assigned parameters are verified,which is helpful for the design of space solar cell arrays for the satellites operating in the MEO and HEO.
