CaCuS2
metal· JVASP-79228· CaCuS2
CaCuS2 is a ternary metal chalcogenide compound combining calcium, copper, and sulfur, representing an emerging material class in solid-state chemistry and materials research. This compound is primarily investigated for its potential in optoelectronic and photovoltaic applications, where mixed-metal sulfides offer tunable electronic properties and potential cost advantages over conventional semiconductors. As a research-stage material rather than an established industrial product, CaCuS2 belongs to the family of earth-abundant chalcogenides being explored to replace scarce or toxic elements in energy conversion devices.
