CuSnSe2 is a ternary copper-tin-selenide compound belonging to the chalcogenide family of semiconductors. This material is primarily investigated in photovoltaic and thermoelectric research applications, where its semiconductor properties and earth-abundant elemental composition make it a candidate for next-generation solar cells and waste-heat energy conversion devices. CuSnSe2 offers potential advantages over cadmium telluride and other toxic alternatives due to its use of non-toxic, relatively abundant elements, though it remains largely in the research and development phase rather than established high-volume production.
