Synergistic effect of the anti-solvent bath method and improved annealing conditions for high-quality triple cation perovskite thin films.

ABSTRACT: One step solution processing together with anti-solvent engineering is a tested route in producing high-quality perovskite films due to its simplicity and low fabrication costs. Commercialization of perovskites will require replacing the anti-solvent drip process and lowering annealing temperatures to decrease the energy payback time. In this work, we successfully replace the anti-solvent drip with the anti-solvent bath (ASB) method through balancing the methylammonium (MA) and formamidinium (FA) cations to produce high-quality cesium (Cs)/FA/MA triple cation perovskite films. Furthermore, the annealing parameters of Cs_0.05FA_0.16MA_0.79PbI_2.7Br_0.3 are enhanced to allow for a low-temperature fabrication process when paired with the ASB m
