Mechanically durable transparent electrodes are needed in flexible optoelectronic devices to implement their long-term stable operating for applications in rollable fields. Indium-tin-oxide (ITO), which is most typically used as a transparent electrode, is not suitable to be applied to flexible substrates. Among several promising transparent electrodes to replace ITO, metal mesh has various advantages while being applicable to flexible substrate. However, the produced sample has a disadvantages of surface roughness, voids, and etc. Therefore, we designed hybrid electrode constitute of PEDOT:PSS with metal mesh to compensate that several problems. As a result, the hybrid electrode of the metal mesh and PEDOT:PSS had an average transmittance of 80% at 550 nm, and a sheet resistance of 0.2 Ω/sq. Moreover, due to the excellent mechanical properties of the hybrid electrode, manufactured OPVs were very stable in extreme environment. |
