IMM四结太阳电池辐照实验方法研究

Study of electron irradiation method for IMM 4J solar cells

空间用反向生长四结砷化镓太阳电池(简称"IMM四结电池")是一种新型的高效太阳电池,将应用于空间飞行器,因此,抗带电粒子辐照性能极为重要。用三种不同抗带电粒子辐照实验的方法进行实验比较,结果表明,电池进行实验后,在(25±5)℃、AM0光照环境退火48 h,再在60℃环境退火24 h,电性能恢复效果最好,最佳功率衰降为18.39%,该方法与电池的使用环境相近,可以作为IMM四结电池的电子辐照实验方法。

IMM 4J solar cell was a new high efficiency solar cell, they were being pursued for space applications, and the performance of electron irradiation was very important. Three different electron irradiation tests methods were used to compare. The results show that the cells irradiated with 1 S.C.（AM0） for 48 h, temperature annealed for 24 h at 60 ℃, then the recovery of the electric characteristic was the best, the degradation of Pmax was 18.39%. The test condition was close to the work condition of solar cells, it could be used as experimental conditions.
