Differential growth and evaluation of band structure of π-SnS for thin-film solar cell applications

摘要

Thin-films and nanomaterials with asymmetrical centers are widely used, and a representative example is pi-SnS. The cubic phase of SnS is a "thermodynamic metastable" polymorph of SnS that has not been investigated extensively. Maintaining the stability of pi-SnS intact and device fabrication are challenging owing to the lack of proper understanding of the nucleation and growth properties. We report a substrate-specific differential growth attribute of pi-SnS based on the chemical deposition route. We evaluated the optical properties and band structure of pi-SnS and achieved an efficiency of similar to 0.12% for a preliminary thin-film solar cell device. (c) 2020 Elsevier B.V.
