•The inorganic salts were liberated from PPy NCPs shell during the CsPbI3 precursor film annealing process.•The liberated LiCl can deactivate point defects, optimize the energy level at the TiO2/perovskite interface, and enhance CsPbI3 crystallinity.•Compared to NaCl@PPy NCPs-TiO2, ZnCl2@PPy NCPs-Ti...
