· CuSbS2

CuSbS2 is a ternary chalcogenide semiconductor compound combining copper, antimony, and sulfur. This material belongs to the family of I-V-VI semiconductors and is primarily explored in photovoltaic and thermoelectric research applications, where its direct bandgap and favorable electronic properties offer potential for thin-film solar cells and energy conversion devices. While not yet widely commercialized compared to mainstream semiconductors, CuSbS2 is notable for its earth-abundant constituent elements and compatibility with low-temperature solution-based manufacturing processes, making it an attractive candidate for cost-effective and scalable alternative energy technologies.
