One of the most effective methods to achieve high-performance perovskite solar cells has been to include additives to precursor solutions that serve as dopants, crystallization agents, or passivate defect sites. In this work, we systematically study the function of methylamine chloride (MACl) additive in formamidinium lead iodide (FAPbI3)-based perovskite thin films. Using density functional theory, we provide a theoretical frame work for understanding the interaction of MACl with a perovskite active layer. We show that MACl successfully induces an intermediate to the pure FAPbI3 α-phase with out annealing, effectively stabilizing this structure only through cationic site substitution. |
