· Cu2 Se2

Cu₂Se₂ is a binary copper selenide semiconductor compound belonging to the chalcogenide family, characterized by copper and selenium in a 1:1 ratio. This material is primarily of research and developmental interest for thermoelectric and photovoltaic applications, where its semiconducting properties and thermal transport characteristics make it relevant for energy conversion devices; it is also investigated in quantum dot synthesis and thin-film electronics where solution-processable copper selenide phases offer potential advantages in cost and manufacturing flexibility compared to conventional inorganic semiconductors.
