Abstract

Methylammonium bismuth iodide (MA₃Bi₂I₉) perovskite, has been deposited on a mesoporous TiO₂ film with high homogeneousity and coverage through interdiffusion of solution-processed BiI₃/CH₃NH₃I stacking layers, resulting in higher power conversion efficiency in the perovskite solar cell as compared with that prepared using a conventional one-step solution method.
