CaSnS3

CaSnS3 is a ternary ceramic compound combining calcium, tin, and sulfur, belonging to the class of sulfide ceramics with potential semiconductor or photovoltaic applications. This is primarily a research-phase material rather than an established commercial compound; it is investigated for its optical and electronic properties in the context of thin-film solar cells, photodetectors, and other optoelectronic devices where sulfide semiconductors offer advantages in bandgap tuning and light absorption. Interest in this material family stems from the search for earth-abundant, non-toxic alternatives to conventional semiconductor systems, though CaSnS3 remains largely in academic development and has not achieved widespread industrial deployment.
