Cu2SnSe4 is a quaternary semiconductor compound belonging to the chalcogenide family, combining copper, tin, and selenium in a crystalline structure. This material is primarily investigated in photovoltaic research and thermoelectric applications, where its tunable bandgap and moderate mechanical properties make it an alternative to more toxic or scarce semiconductor systems; it is not yet widely deployed in mainstream commercial production but represents a promising research direction for cost-effective, earth-abundant solar cells and waste-heat recovery devices.
