【摘要】 文章首先在辐照条件下测试GaInP2/GaAs/Ge三结太阳电池的光谱响应,确定了三结电池在轨道带电粒子辐照条件下的损伤特征。通过试验获得了在不同粒子辐照条件下电池电性能退化规律,由此确定了高能电子与质子辐照对三结电池损伤的等效参数,建立了三结电池最大输出功率随位移损伤剂量的退化方程。在此基础上,以地球同步轨道服役的太阳电池为例,计算了电池在轨等效位移损伤剂量,并对三结电池的在轨服役行为进行了评价。更多还原

【Abstract】 In this paper,the damage characteristics were determined firstly by measuring the spectral responses of triple-junction(TJ) GaInP2/GaAs/Ge solar cells.Then the electrical properties of the TJ cells were determined as a function of the fluences under the irradiation of various charged particles,and the equivalent coefficients related to the irradiated displacement-damage were determined.Based on these results,an evolution law of the mass output power was established as a function of the displacement damage dose of the TJ solar cells under the charged particle irradiation.Finally,the displacement damage dose of the TJ solar cells served in GEO was calculated,from which the orbital behaviors of the TJ solar cell could be evaluated.更多还原
