The preparation of a reduced graphene oxide (pr-Go) is with a novel p-TosNHNH2 reductant is demonstrated for use as an efficient anode interfacial layer for high-performance and highstability organic solar cells (OSCs). The efficiency of the cells with pr-GO is highly comparable to those of the PEDOT:PSSbased devices. Furthermore, the pr-GO based OSCs show a much longer cell life time in air stability tests in comparison with PEDOT:PSS-based cells.
