From Solutions to Photovoltaic Devices: Assessing the Impact of Zn Complexation for Bifacial Cu₂ZnSn(S,Se)₄ Thin Films.

ABSTRACT: Solution-based deposition of high-quality inorganic compound semiconductors onto a variety of substrates is a key challenge toward integrating photovoltaic technologies into a wide range of infrastructures. Cu₂ZnSn-(S,Se)₄ (CZTSSe) is one of the most promising solar absorbers processable by solution-based methods, however there is a substantial knowledge gap linking the chemistry of cation complexes and chalcogen precursors, e.g. thiourea (TU), to the microstructure and opto-electronic properties of the thin-films. In this study, we focus our attention on the complexation of zinc chloride (ZnCl₂) and zinc acetate (ZnAc₂) in dimethylformamide (DMF)-based CZTS precursor inks and how this ultimately affects the performance of CZTSSe thin-film device
