Cu2 Se4

Cu2Se4 is a quaternary copper selenide semiconductor compound that belongs to the family of metal chalcogenides. It is primarily investigated in research contexts for thermoelectric energy conversion applications and advanced photovoltaic devices, where its tunable electronic properties and potential for efficient charge carrier transport make it an attractive alternative to traditional silicon-based semiconductors. The material's structural stability and compositional flexibility position it as a candidate for next-generation solar cells, solid-state cooling devices, and waste heat recovery systems where conventional semiconductors face thermal or efficiency limitations.
