Graphene film converted from spin-coated fullerene derivative as transparent electrode for organic photovoltaics |
초록 |
We report a simple method for growing wafer-scale graphene films using PCBM (phenyl-C61-butyric acid methyl ester), a fullerene derivative, as a solid carbon source. PCBM films spin-coated on nickel catalyst were easily converted to graphene films having a thickness of a few layers by thermal annealing without any reactive gas. This method of converting PCBM to graphene is safe, unlike the chemical vapor deposition method that uses explosive precursor gases. PCBM-derived graphene films were also transferred through a simple process to plastic substrates with a supporting layer for use in organic photovoltaics. The power conversion efficiency of bulk-heterojunction organic photovoltaics prepared on the PCBM-derived graphene electrode was 0.98%. This study indicates that PCBM-derived graphene films can serve as an inexpensive, flexible alternative to indium tin oxide films, and therefore, they can improve the economic viability and flexibility of organic photovoltaics. |
