A robust perovskite-buried interface is pivotal for achieving high-performance flexible indoor photovoltaics as it significantly influences charge transport and extraction efficiency. Herein, a molecular bridge strategy introduced utilizing sodium 2-cyanoacetate (SZC) additive at the to simultaneously achieve in situ passivation of interfacial defects bottom-up crystallization modulation, resulting photovoltaic applications. Supported by both theoretical calculations experimental evidences, illustrates how SZCs serve bridges, establishing bonds between SnO
