Cu2SnSe3
Cu2SnSe3 is a copper-tin-selenide semiconductor used in the development of thin-film solar energy conversion devices.
About Cu2SnSe3
Cu2SnSe3 is a ternary chalcogenide semiconductor that functions as a promising absorber material for thin-film photovoltaic technologies. Its electronic structure is characterized by a very narrow band gap, positioning it as a semimetallic candidate within the broader family of copper-based chalcogenides.
The material exhibits favorable thermodynamic stability, placing it near the convex hull of its phase diagram, which suggests it is a viable target for experimental synthesis. Its structural versatility is evidenced by numerous reported configurations, making it a subject of significant interest for researchers optimizing light-harvesting efficiency.
Key Properties
Cross-validated computational properties for Cu2SnSe3, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the chalcogenide photovoltaic absorbers class.
Within the class of chalcogenide photovoltaic absorbers, Cu2SnSe3 serves as a selenium-based counterpart to the sulfur-rich Cu2SnS3. While many of its siblings like CuInLa2Se5 or Cu2Ga2Se4 rely on different elemental combinations to tune their electronic properties, Cu2SnSe3 is particularly notable for its narrow-gap behavior, offering a distinct alternative for spectral response modulation compared to the wider-gap members of the group.
