The preparation of Ag 3 BiBr 6 films and their preliminary use for solution processed photovoltaics
2019
Bismuth-halide-based perovskites could be promising candidates for construction of lead-free and air-stable perovskites solar cells. Herein we report a simple strategy on the fabrication of the Ag3BiBr6 thin films. They were prepared by flexible spin-coating procedure and the solvent of N-butylamine is found to be critical to dissolving AgBr precursor solution under lower room temperatures. Experiment and calculation analysis both reveal it with hexagonal structure. Their physical properties and photovoltaic performance were both characterized. We demonstrate that Ag3BiBr6 films are capable of storing stably over 30 days in air. These results will inspire more research works on developing and applying Ag3BiBr6 beyond solar energy applications.
