The instability of the buried interface poses a serious challenge for commercializing perovskite photovoltaic technology. Herein, we report polydentate ligand reinforced chelating strategy to strengthen stability by managing interfacial defects and stress. bis(2,2,2-trifluoroethyl) (methoxycarbonylmethyl)phosphonate (BTP) is employed manipulate interface.
