摘　　要：为提高激光无线传能系统接收端的光电转换效率、对比验证接收端不同优化设计方法的优劣,开展了光电阵列不同排布方式的实验研究。分别研制了单一串联排布、顺次串并排布、依据照度分布的串并排布三种光电池阵列,并开展了实验研究。在高斯分布光斑照射下,对比了顺次串并排布与依据照度分布的串并排布输出特性,并对比了单一串联排布在均匀光照下的输出特性。结果表明,不同串并联方式、不同光照条件下,得到的光电效率区别较大。单一串联排布在均匀光照下光电转换效率最高,为39.14%;在高斯分布光照条件下,依据照度分布的串并排布光电转换效率为33.3%,比顺次串并排布效率高出一倍。该结果可对激光无线传能系统接收端的优化设计提供参考。In order to improve the photoelectric conversion efficiency at the receiving end of the laser wireless energy transmission system,and to compare and verify the advantages and disadvantages of different optimization design methods at the receiving end,experimental studies on different arrangements of photoelectric arrays are carried out.In this paper,three types of photovoltaic arrays,a single series layout,a sequential series-parallel combination layout,and a series-parallel combination layout based on the illumination distribution,are developed and experimentally investigated.Under Gaussian distributed spot irradiation,the output characteristics of the sequential series-parallel arrangement and the series-parallel arrangement based on illumination distribution are compared,and the output characteristics of the single series-parallel arrangement under uniform illumination are alsocompared.The results show that the photoelectric efficiencies obtained in different series-parallel arrangements and under different illumination conditions are quite different.The single series arrangement has the highest photoelectric conversion efficiency under uniform illumination,which is 39.14%.And under Gaussian distributed illumination,the photoelectric conversion efficiency of the series-parallel arrangement based on the illumination distribution is 33.3%,which is twice as much as the efficiency of the sequential series-parallel arrangement.The results can provide a reference for the optimal design of the receiving end of the laser wireless energy transmission system.
