化学浴沉积（CBD）ZnOS工艺已被设计成产生可重复且稳健的ZnOS/CIGS太阳能电池，其不需要光浸泡或退火以达到与CdS/CIGS太阳能电池相当的转换效率水平。在这项研究中，铜含量在很大范围内变化，以了解其对这些器械的影响。电容和温度依赖的性能测量被用来表征作为Cu组合物的函数的电性能。发现最佳Cu浓度对于CBD CdS和CBD ZnOS结都是大约相同的。
A chemical bath deposition (CBD) ZnOS process has been designed to yield repeatable and robust ZnOS/CIGS solar cells that do not require light soaking or annealing to reach conversion efficiency levels comparable with CdS/CIGS solar cells. In this study, copper content was varied over a wide range to understand its impact on these devices. Capacitance and temperature-dependent performance measurements were used to characterize the electrical performance as a function of Cu composition. The optimum Cu concentration was found to be about the same for both CBD CdS and CBD ZnOS junctions.
