High-performance perovskite solar cells (PSCs) require synergistic passivation strategies to address defects at the electron transport layer (ETL)/perovskite interface, impacting both efficiency and long-term stability. This study introduces chloramine hydrochlorides (CAHs) - 2-Chloroethylamine Hydrochloride (CEA), Bis(2-chloroethyl)amine Hydrochloride (BCEA), and Tris(2-Chloroethyl)Amine Hydrochloride (TCEA) - as bifunctional molecular bridges to simultaneously passivate defects at both ETL (SnO) and perovskite interfaces while controlling crystallization. Density functional theory calculations showed that TCEA forms strong Sn─Cl bonds, enhancing Sn⁴ coordination.
