Growth of semiconducting nanostructures on graphene would open up opportunities for the development of ﬂexible optoelectronic devices, but challenges remain in preserving the structural and electrical properties of graphene during this process. We demonstrate growth of highly uniform and well-aligned ZnO nanowire arrays on graphene by modifying the graphene surface with conductive polymer interlayers. On the basis of this structure, we then demonstrate graphene cathode-based hybrid solar cells using two diﬀerent photoactive materials, PbS quantum dots and the conjugated polymer P3HT, with AM 1.5G power conversion eﬃciencies of 4.2% and 0.5%, respectively, approaching the performance of ITO-based devices with similar architectures. Our method preserves beneﬁcial properties of graphene and demonstrates that it can serve as a viable replacement for ITO in various photovoltaic device conﬁgurations.
