Abstract Scope	Photovoltaics (PVs), which convert solar energy into electricity, is one of the promising energy devices which can decrease a dependance on fossil energy. Recently, organo-lead-halide perovskite, CH3NH3PbX3 (X=I, Cl, Br) has attracted a huge amount of interest due to its excellent light absorption and carrier transport for the perovskite solar cells (PSCs). Despite these advantages, commercialization of PSCs is still challenging due to poor stability when exposed to humid. Here, we present a simple and effective passivation method to elongate the lifetime of the PSC devices. Interpenetrating polymer networks (IPNs) with PMMA and PU showed better passivation behavior than individual polymer. In addition, the combination of oxide nanoparticles with the IPNs make a twisted path for the permeating water molecule and changed their physical properties. As a result, the encapsulated devices exhibit dramatically suppressed degradation process in a standardized damp heat aging condition (85/85 ℃/RH condition).
