· JVASP-13103· Sr2SnS4

Sr2SnS4 is a mixed-metal sulfide ceramic compound containing strontium and tin, belonging to the family of metal chalcogenides with potential semiconductor or photovoltaic properties. This material is primarily investigated in research contexts for optoelectronic and energy conversion applications, where its band gap and crystal structure make it a candidate for next-generation solar cells, photodetectors, or other light-responsive devices. As a relatively unexplored compound compared to mainstream photovoltaic materials, Sr2SnS4 represents an emerging option for researchers seeking alternatives to conventional cadmium or lead-based chalcogenides, with particular interest in non-toxic, earth-abundant semiconductor platforms.
