Abstract: A method including depositing a lead halide precursor ink onto a substrate; drying the lead halide precursor ink to form a first thin film; annealing the first thin film; and forming a perovskite material layer, wherein forming the perovskite material layer includes: depositing a benzylammonium halide precursor ink onto the first thin film; drying the benzylammonium halide precursor ink; depositing a formamidinium halide precursor ink onto the benzylammonium halide precursor ink; drying the formamidinium halide precursor ink to form a second thin film; and annealing the second thin film.
