Abstract

Control of the nucleation and growth of the CH ₃ NH ₃ PbI ₃ (MAPbI ₃ ) phase is one of the important issues in the development of the high-performance MAPbI ₃ perovskite solar cells. In this work, we demonstrated a novel and easy nucleation-controlling process to fabricate high-performance MAPbI ₃ solar cells using lead acetate as a precursor. The morphology and crystallinity of the final annealed perovskite film is greatly influenced by the intermediate phase in the precursor film. Efficient removal of the solvent and reactants by the use of long-time spin coating process makes the MAPbI ₃ nucleate at room temperature and grain coarsening during the anneal, resulting in the annealed films with smooth surface and high compactness. Precise control of the spin coating time made the average power conversion efficiency of the MAPbI ₃ solar cells increase from 12-13% to 15-16%.
