Cu<sub>2</sub>ZnSn-(S,Se)<sub>4</sub> (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 (ZnCl<sub>2</sub>) and zinc acetate (ZnAc<sub>2</sub>) in dimethylformamide (DMF)-based CZTS precursor inks and how this ultimately affects the performance of CZTSSe thin-film deviceACS applied energy materials15258-15267https://www.ebi.ac.uk/biostudies/studies/S-EPMC12569970biostudies-literatureFrom Solutions to Photovoltaic Devices: Assessing the Impact of Zn Complexation for Bifacial Cu<sub>2</sub>ZnSn(S,Se)<sub>4</sub> Thin Films.PMC12569970Benhaddou NBowers JWKenyon JMahmoud LFermin DJSheppard ABlack AWfalseFrom Solutions to Photovoltaic Devices: Assessing the Impact of Zn Complexation for Bifacial Cu<sub>2</sub>ZnSn(S,Se)<sub>4</sub> Thin Films.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.
