Y6 Cu2 Sn2 S14
semiconductor· Y6 Cu2 Sn2 S14
Y6Cu2Sn2S14 is a quaternary sulfide semiconductor compound combining yttrium, copper, tin, and sulfur in a mixed-valence structure. This material belongs to the family of complex metal sulfides under active research for photovoltaic and thermoelectric applications, where the combination of earth-abundant elements (copper, tin, sulfur) with rare-earth doping (yttrium) aims to achieve tunable bandgaps and improved charge transport. While not yet commercially deployed at scale, compounds in this class are investigated as alternatives to conventional CdTe or CIGS solar absorbers and for solid-state thermoelectric generators, offering potential cost and toxicity advantages if performance targets are met.
