ABSTRACT: The surface topography of the lead halide perovskite layer is a crucial aspect that influences the performance of perovskite solar cells (PSCs). In this work, two different quenching approaches for the crystallization of Cs0.15FA0.85Pb(I0.6Br0.4)3 perovskite films are investigated: antisolvent quenching and gas quenching. Both methods, aimed at removing the solvent of the precursor solution and initiating the perovskite nucleation, differ mechanistically and result in different rates of crystallization, which cause surface topographical irregularities, in the form of elongated and elevated structures on the films, termed "wrinkles". This study shows that antisolvent-quenched perovskite films exhibit a higher density of wrinkles than th
