Description
Summary: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.
