· SmCuSeO

SmCuSeO is an experimental quaternary semiconductor compound containing samarium, copper, selenium, and oxygen. This material belongs to the family of mixed-metal chalcogenides and oxides, which are of research interest for photovoltaic and optoelectronic applications due to their tunable bandgap and potential for charge transport. While not yet commercialized at scale, compounds in this family are investigated for next-generation solar cells, photodetectors, and photocatalytic devices where earth-abundant or rare-earth-doped semiconductors could offer advantages in efficiency or cost-performance tradeoffs compared to conventional silicon or cadmium telluride technologies.
