Summary: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. The effect of passivation and the underlying mechanism were investigated by an in-depth study of 2-(phenylamino)ethane-1-amine salts (PNEA + ) with different halide anions. The inverted PSC based on PNEACl provided a champion PCE of 21%.
