Cu4Sn7S16
semiconductor· Cu4Sn7S16
Cu4Sn7S16 is a quaternary semiconductor compound combining copper, tin, and sulfur in a fixed stoichiometric ratio, belonging to the sulfide semiconductor family. This material is primarily of research interest for photovoltaic and thermoelectric applications, where the combination of earth-abundant elements (copper and tin) and tunable bandgap make it potentially attractive as an alternative to conventional semiconductor materials. While not yet widely commercialized, Cu4Sn7S16 represents an emerging class of low-cost, non-toxic semiconductors being investigated to reduce dependence on rare elements and toxic materials in energy conversion devices.
