“…The use of ternary chalcogenide thin films in optoelectronic devices has increased during the past few decades due to their special optical and electronic characteristics, as well as the fact that they are affordable, simple to produce and use on a large scale, and environmentally friendly. For optoelectronic devices and applications, different ternary sulfo‐selenides, including CdSSe, SnSSe, ZnSSe, WSSe, Sb 2 SSe, and MoSSe, have been demonstrated in numerous investigations [15–23] . Tin (II) sulfo‐selenide (SnSSe), one of the sulfosalt materials on which we focus, has demonstrated promising performance for a wide range of applications in optoelectronic devices owing to its advantageous electrical and optical properties, which fall in between those of SnS and SnSe [22,23] .…”
