The reduced-graphene-oxide/Au(R. GO/Au) composite microelectrode array was fabricated by a simple method. The graphene oxide(GO) array was prepared by two beam interference-holographic lithography technique, and then reduced by hydrazine vapor to partially remove the oxygen. containing groups. Ultra-thin Au film was deposited on the reduced. graphene-oxide(R-GO) array to improve its conductivity. The results indicate that R-GO/Au composite microelectrode array exhibits excellent surface morphology with precisely controlled period and high resolution, good transparency in visible light region and high conductivity. The organic photovoltaic device based on the R. GO/Au composite microelectrode array exhibits a high power con. version efficiency of 3. 43%.
