Abstract

Highlights: A new method of fabricating 2D pervoskite thin film by single-source physical vapour deposition was proposed. High level of phase-purity and crystallinity with stoichiometry after in-situ annealed. A photovoltaic efficiency of approximately 4.5% with no hysteresis was obtained. Abstract: Hysteresis-free two-dimensional (2D) pervoskite solar cells are prepared by single-source physical vapour deposition (SSPVD). The (BA)2 (MA)3 Pb4 I13 2D perovskite films are prepared by thermal evaporating their crystal powder and post-annealing. The dense and uniform films are formed on the surface, with high crystallization and full surface coverage. Especially, these films exhibit good chemical accordance with the precursors and optical properties. A photovoltaic efficiency of approximately 4.5% with no hysteresis was obtained for (BA)2 (MA)3 Pb4 I13 solar cells fabricated by SSPVD. These initial results suggest that single-source physical vapour deposition is a promising method for preparing high-quality complicated multi-cation 2D perovskite films for solar application.
