均匀的分子前体溶液是获得光滑吸收层的极好选择，并且它们提供了显著降低太阳能电池制造成本的潜力。在这里，我们提出了一种热降解的金属丁基二硫代氨基甲酸酯为基础的解决方案的方法来制造Cu2ZnSn（S，Se）（4）太阳能电池。以廉价的Cu_2O、ZnO和SnO为原料，将其溶解于丁基二硫代氨基甲酸的乙醇溶液中，通过调整Cu2ZnSn（S，Se）（4）薄膜的成分，实现了基于有源面积的6.03%的功率转换效率。
Homogeneous molecular precursor solutions are excellent choices for obtaining smooth absorber layers, and they offer the potential to significantly lower the manufacturing cost of solar cells. Here, we present a thermally degradable metal butyldithiocarbamate-based solution approach to fabricate Cu2ZnSn(S,Se)(4) solar cells. Low-cost Cu2O, ZnO, and SnO were used as the starting materials and were dissolved in the ethanol solution of butyldithiocarbamic acid. By tuning the composition of the Cu2ZnSn(S,Se)(4) thin film, a power conversion efficiency of 6.03% on the basis of the active area has been achieved.
