Composite transparent conductive electrode for printed electronic devices

The new transparent conductive electrode consists of three materials: silver nanowires (AgNWs), zinc oxide nanoparticles (ZnO), and reduced graphene oxide (rGO). We prepared a silver nanowire electrode by spin coating a silver nanowire solution on a glass substrate, the zinc oxide nanoparticles covered the silver nanowire grid and filled the gap of silver nanowire, which enhanced the adhesion of silver nanowire to the substrate. The outermost reduced graphene oxide provides protection for the material and improves the stability of the electrode in an air environment. The AgNWs/ZnO/rGO composite electrode prepared has a sheet resistance of about 9.96 Ω/sq and a light transmittance of 71% (T550), which has good photoelectric properties. Experimental results show that the composite electrode has long-term stability in air.
