Graphene, a two-dimensional carbon atom sheet with a honeycomb lattice, has shown outstanding properties. Specially due to the outstanding properties, graphene have been received significant attention as a promising transparent electrode for a indium tin oxide (ITO) alternative. However, for real commercialization of graphene films and for the use as a key material in semiconductor based technologies, control of optoelectronic properties of graphene films via a controllable graphene structural modification should be studied. Herein, we introduce efficient electron beam-irradiation based modification of graphene and its application as a transparent electrode in organic solar cells. With various irradiation conditions such as time, the changes in properties of graphene electrode have been systemically investigated. In addition, we have also studied their effects as transparent electrodes and interfacial materials on cell-performances in organic solar cells, respectively. |
