Photovoltaic Performance of Flexible Graphene-Electrodes Prepared by a Simple Chemical Vapor Graphitization
When the graphene oxide (GO) film on plastic substrate was treated with HI-gas, a reduced graphene oxide (RGO) film with the conductivity 14.1 S/cm and the transparence of 34.7% at 550nm was successfully obtained. Despite the low conductivity of the RGO electrode, the flexible organic solar cells fabricated on the RGO electrode showed a power conversion efficiency of approximate to 0.37% (FF: 0.25, V-OC: 0.58V and J(SC): 2.41mA/cm(2)), indicating the possibility of using RGO as a flexible and transparent electrode for polymer-based flexible solar cells.
