Abandoning the traditional deposition of as-prepared Cu₂ZnSnS₄ (CZTS) thin films in a glove box, a modified thiol-based solution system suitable for deposition in air is described to further reduce device production costs. In this modified approach, metal salts and thiourea are used as the starting materials and are dissolved in a mixed solution of thioglycolic acid and 2-methoxyethanol, forming a homogeneous precursor solution. The as-deposited CZTS thin films are obtained by spin-coating the precursor solution in air, followed by the selenization process to form large-grained Cu₂ZnSn(S,Se)₄ thin films. Combining the microstructural results with compositional analyses, the optimal selenization conditions for the Cu₂ZnSn(S,Se)₄ absorber layer were found to be 540°C and 10 min.

放弃了在手套箱中传统制备的Cu ₂ ZnSnS ₄（CZTS）薄膜的传统沉积方法，描述了一种适用于在空气中沉积的改进的基于硫醇的溶液系统，以进一步降低装置的生产成本。在这种改进的方法中，金属盐和硫脲用作原料，并溶解在巯基乙酸和2-甲氧基乙醇的混合溶液中，形成均质的前体溶液。沉积后的CZTS薄膜是通过在空气中旋涂前体溶液，然后进行硒化处理以形成大晶粒的Cu ₂ ZnSn（S，Se）₄薄膜而获得的。将微观结构结果与成分分析相结合，得出Cu ₂的最佳硒化条件ZnSn（S，Se）₄吸收层的温度为540°C，10分钟。
