Ca3La2(SnS4)3

Ca3La2(SnS4)3 is a complex sulfide semiconductor compound combining calcium, lanthanum, and tin sulfide units in a layered crystal structure. This is primarily a research material explored for photovoltaic and optoelectronic applications, particularly in the context of thin-film solar cells and light-emitting devices where wide-bandgap or tunable electronic properties are advantageous. The mixed-cation sulfide framework offers potential advantages over conventional semiconductors in terms of compositional flexibility and thermal stability, though it remains largely in the experimental phase without widespread industrial deployment.
