"In this work, the one-step and the two-step methods were used to deposit MAPbI3 perovskite films. For both methods, there are several variables to control the perovskite formation and film quality. The influence of anti-solvent, the time for its addition, and the annealing temperature on the features of perovskite films were studied for the one-step method. The temperature for deposition of the inorganic film was studied for the close-spaced sublimation method, and the time that MAI-solution remains onto the PbI2 film before the spin process began was studied for spin-coating with sequential deposition methods."
