· JVASP-90668· ZnCu2SnS4

ZnCu2SnS4 is a quaternary sulfide compound belonging to the kesterite family of semiconductors, characterized by a diamond-like crystal structure with mixed-metal cation sites. This material is primarily investigated as a thin-film photovoltaic absorber for next-generation solar cells and as a potential thermoelectric material, offering a less toxic and more Earth-abundant alternative to established chalcopyrite semiconductors. Its appeal lies in tunable bandgap properties and compatibility with scalable deposition techniques, though it remains largely in the research and development phase compared to commercialized photovoltaic materials.
