A simple direct solution coating process for forming CuInSe₂ (CIS) thin films was described, employing a low-cost and environmentally friendly precursor solution. The precursor solution was prepared by mixing metal acetates, ethanol, and ethanolamine. The facile formation of a precursor solution without the need to prefabricate nanoparticles enables a rapid and easy processing, and the high stability of the solution in air further ensures the precursor preparation and the film deposition in ambient conditions without a glove box. The thin film solar cell fabricated with the absorber film prepared by this route showed an initial conversion efficiency of as high as 7.72 %.
一种简单的直接溶液涂覆工艺被用来制备铜铟硒（CIS）薄膜，该工艺采用了一种低成本且环保的前驱体溶液。前驱体溶液通过混合醋酸盐、乙醇和乙醇胺制备而成。这种前驱体溶液的制备方法无需预先制备纳米颗粒，因此能够实现快速简便的处理过程，而且溶液在空气中的高稳定性也确保了前驱体的制备和薄膜沉积可以在环境条件下进行，无需手套箱。使用该路线制备的吸收膜制成的薄膜太阳能电池的初始转换效率高达 7.72%。
