Rational Design of Hybrid Graphene Films for High-Performance Transparent Electrodes

Transparent, flexible conducting films were fabricated by using a metallic grid and graphene hybrid film. Transparent electrodes using the hybrid film and transparent substrate such as glass or polyethylene terephthalate (PET),films were assembled. The sheet resistance of the :fabricated transparent electrodes was as low as 3 Omega/square with,the transmittance at similar to 80%. At 90% transmittance, the sheet resistance was similar to 20 Omega/square. Both-values are among the highest for transparent electrode materials to date. The materials used for the new hybrid electrode are earth-abundant stable elements, which increase their potential usefulness for replacement of indium tin oxide (ITO) in many applications.
