· JVASP-119194· CuSeS

CuSeS is a ternary copper selenide sulfide compound that belongs to the family of mixed-anion chalcogenides. This material is primarily of research interest for semiconductor and photovoltaic applications, where the combination of copper, selenium, and sulfur creates tunable electronic properties for light absorption and charge transport. Industrial adoption remains limited, but the material shows promise in thin-film solar cells and thermoelectric devices as a lower-toxicity alternative to lead-based or cadmium-based semiconductors.
