· JVASP-155391· Cu2SnPbS4

Cu2SnPbS4 is a quaternary sulfide compound belonging to the metal chalcogenide family, combining copper, tin, lead, and sulfur in a fixed stoichiometric ratio. This material is primarily of research interest for photovoltaic and optoelectronic applications, where mixed-metal sulfides are explored as potential absorber layers or secondary phases in thin-film solar cells and related semiconductor devices. The compound's notable characteristic is its combination of multiple p-block and d-block elements, which can produce tunable bandgap properties and relatively high absorption coefficients—attributes that make it a candidate for next-generation absorber materials where conventional semiconductors face cost or efficiency limitations.
