· JVASP-108718· ZnCu2SnSeS3

ZnCu2SnSeS3 is a quaternary chalcogenide compound belonging to the family of copper-tin-based semiconductors with selenium and sulfur anionic components. This is an experimental/research material primarily of interest for photovoltaic and thermoelectric applications, as compounds in this family combine tunable bandgaps with moderate thermal conductivity, making them candidates for next-generation thin-film solar cells and waste-heat recovery devices. The material represents an alternative to established kesterite and related absorber layers, offering potential cost advantages through earth-abundant constituent elements compared to conventional semiconductors.
