Perovskite solar cell (PSC) commercialization faces intrinsic stability and efficiency challenges. N-1-phenylethane-1,2-diamine hydrohalides (PNEAX) based on a new design strategy featuring cation and anion optimization have been developed for efficient interfacial passivation. Among them, PNEACl-treated devices achieved a champion efficiency of 21.01% with good stability.
