Ultrabarriers that are impermeable, flexible, and optically transparent are achieved by uniform and continuous thin (≈10 nm) films of solution-processed reduced graphene oxide (rGO). The close packing of interlayer distance and restoration of pristine graphene nanoislands induced by the annealing of GO led to substantially improved lifetime of encapsulated organic photovoltaic devices.
