· K2CuVS4

K2CuVS4 is a quaternary sulfide semiconductor compound containing potassium, copper, vanadium, and sulfur. This is a research-phase material being investigated for its electronic and optical properties within the broader family of mixed-metal sulfides, which show promise as photovoltaic absorbers, thermoelectric materials, and catalysts. The vanadium-copper sulfide chemistry is of particular interest for photocatalytic applications and as an alternative absorber layer in thin-film solar devices, though industrial deployment remains limited and material processing methods are still under development.
