Abstract
In this work, Graphene/Copper Nanowire (G/CuNW) based transparent conducting electrodes (TCEs) were prepared via spin-assisted layer-by-layer (LBL) deposition. 3-aminopropyltriethoxysilane (ɣ-APS) functionalized glass substrates were sequentially spin-coated with graphene oxide (GO) and CuNWs. Then, to enhance the electrical conductivity, the multilayer films were subjected to chemical reduction and thermal annealing. The ultimate films were characterized by a scanning electron microscope, UV–Vis spectrometer, and sheet resistance using a four-point probe method. 3-bilayer G/CuNWs films exhibited sheet resistance of 9 Ω/sq and optical transmittance of 67% (at 550 nm), which is comparable to commercial ITO electrode in terms of mainly sheet resistance.
