However, no systematic study on the synthesis and characterization of polycrystalline Sb2(S(1-x)Se(x))3 thin films has been reported. Here, using a hydrazine based solution process, single-phase Sb2(S(1-x)Se(x))3 films were successfully obtained. Through Raman spectroscopy, we have investigated the dissolution mechanism of Sb in hydrazine: 1) the reaction between Sb and S/Se yields [Sb4S7](2-)/[Sb4Se7](2-) ions within their respective solutions; 2) in the Sb-S-Se precursor solutions, Sb, S, and Se were mixed on a molecular level, facilitating the formation of highly uniform polycrystalline Sb2(S(1-x)Se(x))3 thin films at a relatively low temperature.
