半导体的溶液处理，如CuInSe2及其合金(CIGS)，可以显著降低薄膜太阳能电池的制造成本。尽管最近溶液沉积方法在治疗CIGS方面取得了成功，但通常涉及联氨等有毒试剂，这会带来健康和安全方面的问题。在这里，我们提出了一种简单而安全的方法，从二胺/二硫醇的金属硫化物溶液中制备高质量的CuIn(S，硒)2吸收材料。使用层析原子化器将溶液喷洒在空气中，然后进行沉积后硒化步骤。探索了两种不同的硒化方法，得到了高达8%的功率转换效率。
Solution processing of semiconductors, such as CuInSe2 and its alloys (CIGS), can significantly reduce the manufacturing costs of thin film solar cells. Despite the recent success of solution deposition approaches for CIGS, toxic reagents such as hydrazine are usually involved, which introduce health and safety concerns. Here, we present a simple and safer methodology for the preparation of high-quality CuIn(S, Se)2 absorbers from metal sulfide solutions in a diamine/dithiol mixture. The solutions are sprayed in air, using a chromatography atomizer, followed by a postdeposition selenization step. Two different selenization methods are explored resulting in power conversion efficiencies of up to 8%.
