Abstract

This work is dedicated to the description of the degradation of GaAs solar cells under continuous laser irradiation. Constant and strong exposure of the solar cell was performed over two months. Time-dependent electrical characteristics are presented. The structure of the solar cells was studied at the first and last stages of degradation test. The data from Raman spectroscopy, reflectometry, and secondary ion mass spectrometry confirm displacement of titanium and aluminum atoms. X-ray photoelectron spectroscopy showed a slight redistribution of oxygen bonds in the anti-corrosion coating.

摘要

这项工作致力于描述砷化镓太阳能电池在连续激光照射下的退化情况。对太阳能电池进行了为期两个月的持续且强烈的照射。给出了随时间变化的电学特性。在退化测试的第一阶段和最后阶段研究了太阳能电池的结构。拉曼光谱、反射测量和二次离子质谱的数据证实了钛和铝原子的位移。X射线光电子能谱显示了防腐涂层中氧键的轻微重新分布。
