摘要

考察了通过自主研发的高温热裂解辅助硒化装置所产生的高活性硒对CIGS薄膜结构和器件性能的影响.通过调节高温裂解系统的温度可以有效调节不同的硒活性.研究发现

第一台阶HC-Se气氛可以提高CIGS薄膜表面的Ga含量

使得CIGS薄膜内的Ga分布更加平缓

进而提高CIGS薄膜表面禁带宽度.而且HC-Se气氛可以消除CIGS"两相分离"现象.两种因素的共同作用使得CIGS薄膜太阳电池的开路电压提高了34.6%.电池转换效率从6.02%提升至8.76%

增长了45.5%.

Abstract

The influence of cracking selenium on the structure and device parameters of Cu(In

)-Se

(CIGS) thin films was investigated. The activity of cracked selenium can be controlled by moderating the temperature of thermal cracking system employed in our self-designed selenization furnace. The HC-Se atmosphere can enhance the Ga concentration on the film surface and increase the band-gap energy of the CIGS film surface. In addition

HC-Se atmosphere can alleviate the "phase separation". Consequently

value of the solar cell increases about 34.6%. The device conversion efficiency using the novel thermal-cracking system increases by about 45.5% from 6.02% to 8.76%.
