ScCuS2
metal· ScCuS2
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.
