Effect of Antisolvent Application Rate on Film Formation and Photovoltaic Performance of Methylammonium‐Free Perovskite Solar Cells

The poor stability of perovskite solar cells that are based on methylammonium (MA)‐containing compositions has triggered immense interest in the development of MA‐free alternatives such as the double‐cation mixed‐halide Cs x FA1–x Pb(I1–x + Br x )3 composition (CsFA perovskites). Although efficient...
