| 摘 要： | 本文系统研究了Cu(In,Ga)Se2(CIGS)薄膜太阳电池在入射光强为10～100 mW/cm2范围内的性能参数.结果表明,随光强的减弱,CIGS电池的转换效率、填充因子、短路电流密度和开路电压等性能参数逐步衰减;电池参数与光强的依赖关系可明显划分为两个阶段:光强高于75 mW/cm2时,电池性能变化不大;当光强低于70 mW/cm2时,电池性能衰减明显.这是由于随着光强的降低,RS(串联电阻)值和RSH(并联电阻)值都在升高.其中,RSH值的增大使得CIGS电池的弱光特性变好,但较小的RSH值并不能弥补RS所导致电池性能的衰退.最后,发现高Ga含量的CIGS薄膜电池(8.7;)比低Ga含量(6.9;)的电池弱光特性好.

| Abstract: | The parameters of Cu(In,Ga)Se2(CIGS) thin-film solar cells under different irradiance conditions(from 10 mW/cm2 to 100 mW/cm2) were reported in this paper.By lowering the irradiance from standard test conditions towards 10 mW/cm2,the performance of the cells is gradually reduced.This decline isn't notable when the irradiance is above 75 mW/cm2,and becomes obvious when the irradiance is below 70 mW/cm2.Moreover,comparing to low Ga-content(6.9%) cell,the high Ga-content(8.7%) has the better performance under ... |
