Abstract The conventional fabrication of perovskite solar cells (PSCs) has historically relied on toxic solvents, such as dimethylformamide (DMF), N‐methyl‐2‐pyrrolidone (NMP), and chlorobenzene, a practice that is now yielding to more sustainable economically viable alternatives. A one‐step antisolvent‐free methodology developed, guided by the strategy minimizing solvent toxicity enhancing device performance. This method employs N,N‐dimethylacetamide (DMAc) N,N'‐dimethylpropyleneurea (DMPU) alternatives DMF/NMP in fabrication, along with ethanol for hole transport layer. However, formamidinium (FA)‐based films prepared via an process often suffer from severe crystallization issues at buried interface, which lacks rapid removal leads high concentration defects uncoordinated Pb 2+ ions.
