In2CuSe4
metal· JVASP-94929· In2CuSe4
In2CuSe4 is a quaternary semiconductor compound belonging to the chalcogenide family, combining indium, copper, and selenium in a defined stoichiometric ratio. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties make it relevant for thin-film solar cells, photodetectors, and light-emitting devices. While not yet widely commercialized compared to established alternatives like CdTe or CIGS solar absorbers, In2CuSe4 represents an emerging candidate in the search for cost-effective, earth-abundant semiconductor materials with reduced toxicity concerns.
