Cu2AgSnS4
metal· JVASP-155372· Cu2AgSnS4
Cu2AgSnS4 is a quaternary sulfide compound belonging to the tetragonal chalcogenide family, combining copper, silver, tin, and sulfur elements. This material is primarily of research and developmental interest for photovoltaic and thermoelectric applications, where its direct bandgap and mixed-metal composition offer potential advantages over binary sulfides in light absorption and charge transport. The compound represents an emerging candidate in thin-film solar cell research and solid-state energy conversion devices, though it remains less established than conventional alternatives like CIGS (copper indium gallium selenide) or perovskites in commercial deployment.
