CuInS2陶瓷的制备及其结构、性能表征
摘要
CuInS2作为Ⅰ-Ⅲ-Ⅵ族三元化合物半导体,由于其具有高的理论转换效率、光吸收系数、禁带宽度与太阳能光谱匹配性极好及热稳定性好等优点,已经引起人们的广泛关注,被看作是很有发展前景的太阳能电池光吸收材料。本文采用传统的固相烧结法,制备CuInS2陶瓷靶材。确定出具有黄铜矿结构的CuInS2陶瓷靶材制备过程中最佳的粘合剂用量、成型压力、烧结气氛、烧结温度以及保温时间。并在此基本上探索了烧结温度和保温时间对CuInS2陶瓷结构、性能的影响。由实验结果可以看到,CuInS2陶瓷靶材的最佳烧结温度为960℃,最佳保温时间为2h。在此条件下制备出的CuInS2陶瓷具有黄铜矿结构。

Preparation of CuInS2 Ceramic and Characterization of its Structure and Property
Abstract
As a Ⅰ-Ⅲ-Ⅵ ternary pound, copper indium disulfide (CuInS2), with its high theoretical conversion efficiency, high absorption, well match with the solar radiation, good thermal stability and other advantages, has emerged as a promising absorber material for solar cells. CuInS2 ceramic targets were prepared by solid state reaction. The optimal amount of adhesives, molding pressure, sintering atmosphere, sintering temperature and holding time were investigated during the preparation of CuInS2 ceramic target with chalcopyrite structure. And then, the influences caused by the sintering temperature and holding time were investigated on the structure and property of CuInS2 ceramic. The results indicate that CuInS2 ceramic target’s optimum sintering temperature is 960℃ and the optimum holding time is 2h. Under the sintering temperature of 960℃ and the optimum holding time of 2h, CuInS2 ceramic with chalcopyrite structure was prepared.
