a, b Two different views of the optimized structure of 2-layers BP on FAPbI3. c The charge density difference plot for FAPbI3/BP, wherein the depleted/excess charge densities are indicated by green/blue colour regions. Computed Bader charges for Pb atoms at the FAPbI3/BP interface are presented in red numbers, while their corresponding values on bare FAPbI3 perovskite surface are shown in parentheses.
