| 摘 要： | 为了研究激光光强均匀度对GaAs电池转换效率的影响，基于单结GaAs电池的工作原理，利用等效电路对其在受到不同光强激光照射时的光电转换效率进行分析，并通过实验测量不同光强均匀度情况下GaAs串联电池组的光电转换效率。结果表明，光强均匀度对GaAs电池组的光电转换效率有很大影响。在极限条件下，由光强不匀均性引起的热斑效应还会造成电池片的损毁。

| Abstract: | In order to study the effect of light intensity uniformity on the conversion efficiency of GaAs cells, based on the working principle of single junction GaAs cell, the photoelectric conversion efficiency of GaAs cells was analyzed when the laser intensity was different by using the equivalent circuit, and the conversion efficiency of GaAs cells in different light intensity uniformity was studied by experiments. Results show that the light intensity uniformity has a great influence on the photoelectric conversion efficiency of the single junction GaAs cell. In some extreme conditions, it may cause the hot spot effect and completely destroy the GaAs cells. |
