对聚光型太阳电池表面栅极图形进行优化设计.对组成太阳电池表面栅电极的图形最小单元的各种功率损失进行了详细分析,得到了最佳栅电极间距的递推公式.优化计算了各种宽度的次栅之间的间距,并得到了相对应的功率损失比例.电极和半导体接触良好时,当次栅间距小于最佳值,电极的遮挡对于功率损失影响最大;而当次栅间距大于最佳值时,太阳电池体材料输运功率损失和次栅电极电流输运功率损失开始成为主要原因.对于高倍聚光型太阳电池来说,次栅电极的厚度相对要求厚一些.计算及分析结果可应用于聚光型太阳电池电极的设计中.

An optimum grid pattern of the concentrator solar cell top contact metallization was designed.Several power-loss mechanisms of the smallest element were analyzed detailedly.The optimum grid spacing recursion formula was deduced.The optimum grid spacing and the power-loss for the grids of different width were calculated.The shadowing loss was the biggest loss when the grid spacing was narrower than the optimum one if ohmic contact was very well.Otherwise,the current transporting power losses of the grid and solar cell material became the main reason.For the high concentrator solar cell,the thickness of the grid was proposed to be designed more thickly.The results of calculation and analysis can be used in the designing concentrator solar cells.
