Highlights Covalent organic frameworks (COFs) were in situ homogeneously growing on the surface of metal–organic framework (MOF-808) by a covalent bond to construct a core–shell MOF@COF nanoparticle. MOF@COF optimized the crystallinity of perovskite to achieve 23.61% efficiency with superior open circuit voltage (1.20 V). MOF-assisted COFs to ‘trap’ leaked lead ions by in situ chemical fixation and adsorption. The amount of lead leakage (
