ScCuS2 is an experimental ternary chalcogenide compound combining scandium, copper, and sulfur—a material class of significant interest for semiconductor and photovoltaic applications. While not yet established in commercial production, scandium-copper sulfides represent an emerging research frontier for absorber layers in thin-film solar cells and solid-state electronic devices, offering potential advantages in bandgap tunability and earth-abundant element composition compared to conventional cadmium telluride or lead halide alternatives.
