· InCuS2

InCuS₂ is a ternary semiconductor compound combining indium, copper, and sulfur, belonging to the family of chalcopyrite-type semiconductors. This material is primarily of research interest for photovoltaic and optoelectronic applications, where its direct bandgap and light-absorbing properties make it a candidate for thin-film solar cells and photodetectors as an alternative to more established compounds like CIGS (copper indium gallium selenide). While not yet widely commercialized, InCuS₂ represents an experimental approach to reducing reliance on scarce elements in semiconductor technology, though material stability and device efficiency optimization remain active areas of investigation.
