The experimental replicability of highly efficient perovskite solar cells (PSCs) is a persistent challenge faced by laboratories worldwide. Although trace impurities in raw materials can impact the reproducibility high-performance PSCs, situ study how affect film growth never investigated. Here, light shed on inevitable water contamination lead iodide (PbI
