Metal–metal chalcogenide molecular precursors to binary, ternary, and quaternary metal chalcogenide thin films for electronic devices†
Abstract
Bulk metals and metal chalcogenides are found to dissolve in primary amine–dithiol solvent mixtures at ambient conditions. Thin-films of CuS, SnS, ZnS, Cu2Sn(Sx,Se1−x)3, and Cu2ZnSn(SxSe1−x)4 (0 ≤ x ≤ 1) were deposited using the as-dissolved solutions. Cu2ZnSn(SxSe1−x)4 solar cells with efficiencies of 6.84% and 7.02% under AM1.5 illumination were fabricated from two example solution precursors, respectively.
