· Y1 Cu1 Se2

Y1Cu1Se2 is a ternary semiconductor compound combining yttrium, copper, and selenium in a 1:1:2 stoichiometric ratio. This material belongs to the family of chalcogenide semiconductors and represents an emerging research compound with potential applications in optoelectronics and energy conversion, though industrial deployment remains limited compared to established binary semiconductors. The yttrium-copper-selenium system is of interest for its tunable electronic properties and potential use in photovoltaic devices, though the material is primarily in the research and development phase rather than widespread commercial production.
