K2In3CuSe6
semiconductor· K2In3CuSe6
K2In3CuSe6 is a quaternary semiconductor compound belonging to the family of multi-element chalcogenides, combining potassium, indium, copper, and selenium in a layered crystal structure. This material is primarily of research interest for photovoltaic and optoelectronic applications, where its bandgap and electronic properties position it as a potential alternative to traditional II-VI or I-III-VI2 semiconductors. The compound represents exploratory work in thin-film solar cells and thermoelectric devices, where designers seek materials with tunable band structures and reduced toxicity compared to cadmium- or lead-based alternatives.
