摘要
分析了原子氧环境对低地球轨道(LEO)卫星太阳电池电路损伤效应,得到目前常用的太阳电池电路材料中银互联材料和聚酰亚胺膜对原子氧环境较为敏感。采用20μm的可伐互联片及50μm的银互联片样品,开展原子氧试验研究。试验结果表明:在原子氧总通量为1.7×1022 atoms/cm2以下时,可以选择银互联片作为连接介质,不会因为原子氧侵蚀对互联片产生危害。当原子氧总通量为2.5×1022 atoms/cm2以上时,可以考虑采用可伐互联片。文章的研究结果可为适用于高原子氧总通量的太阳电池电路互联片设计提供依据。
The damage effects of LEO atomic oxygen environment on solar cell circuit are analyzed.Silver interconnects and polyimide membranes are sensitive to atomic oxygen in solar cell circuit.Atomic oxygen experiment is carried out for 20μm kovar interconnect and 50μm silver interconnect samples.The experimental results show that when the total atomic oxygen flux is less than 1.7×1022 atoms/cm2,silver interconnect can be selected,and it is not harmful to the interconnect because of the erosion of atomic oxygen;when the total atomic oxygen flux is more than2.5×1022 atoms/cm2,kovar interconnect can be considered.This paper provides a design basis for the selection of solar cell circuit interconnect for high total atomic oxygen flux.
