摘要

制备CdTe薄膜太阳能电池最常用的加工步骤是在CdCI/sub /存在下进行热处理。本文讨论了气相CdCI/sub - 2/热处理对薄膜CdTe/CdS太阳能电池特性的影响。热处理在三种不同的环境下进行，He、O/sub 2/和H/sub 2/，温度范围很广。迄今为止，最佳的太阳能电池性能是在O/ sub2 /存在下热处理的电池。在He和H/sub / 2/中热处理的太阳能电池分别表现出较低的ff和Voc。该工艺经过了高通量优化，并在短退火时间内展示了最先进的Voc和ffs。

Vapor chloride treatment studies of CdTe/CdS solar cells

The most commonly used processing step for the fabrication of CdTe thin film solar cells is a heat treatment in the presence of CdCI/sub 2/. This paper discusses results on the effect of a vapor CdCI/sub 2/ heat treatment on the characteristics of thin film CdTe/CdS solar cells. The heat treatment was carried out in three different ambient environments, He, O/sub 2/, and H/sub 2/, and over a wide range of temperatures. Best solar cell performance to-date was achieved for cells heat-treated in the presence of O/sub 2/. Solar cells heat-treated in He and H/sub 2/ exhibited lower ff's and Voc's respectively. The process was optimized for high throughput and demonstrated state of the art Voc's and ffs for short annealing times.
