· In1.85Cu0.15Se2.85

In1.85Cu0.15Se2.85 is a mixed-cation indium copper selenide compound belonging to the family of chalcogenide semiconductors. This material is primarily of research and developmental interest for photovoltaic and thermoelectric applications, where the partial substitution of copper for indium modifies electronic structure and band gap characteristics compared to binary indium selenide. The composition sits within an active area of exploration for thin-film solar cells and advanced energy conversion devices, offering potential advantages in cost, processability, or performance tuning relative to conventional III–VI or II–VI alternatives.
