About ZnCu2SnSeS3
ZnCu2SnSeS3 is a complex quaternary chalcogenide semiconductor that functions as a potential absorber material for thin-film solar energy conversion. Its composition, incorporating copper, zinc, tin, sulfur, and selenium, positions it within a class of materials designed to optimize light absorption through tunable electronic properties.
As a material residing near the convex hull, it is considered a viable candidate for experimental synthesis. Its near-zero-gap electronic character suggests unique charge carrier behavior, making it an intriguing subject for researchers aiming to refine the efficiency and stability of next-generation photovoltaic devices.
Key Properties
Cross-validated computational properties for ZnCu2SnSeS3, aggregated across 3 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.
