· Cu0.3In1.7Se2.7

Cu0.3In1.7Se2.7 is a quaternary chalcogenide semiconductor compound belonging to the I-III-VI family, structurally related to CuInSe2 (CIS) and commonly studied as an absorber material in thin-film photovoltaic research. This copper-indium-selenide composition is primarily investigated for next-generation solar cell applications where its adjustable bandgap and light-harvesting properties offer potential advantages in efficiency and manufacturing scalability compared to conventional silicon photovoltaics. The material remains largely in research and development phases, with commercial adoption limited to specialized laboratory and pilot-scale photovoltaic fabrication.
