摘要：

We present application results of synthesized graphene films as transparent and conductive electrodes of organic photovoltaic devices. The graphene films were synthesized by chemical vapor deposition (CVD) technique on nickel substrates and showed a low sheet resistance of similar to 605 Omega/square and transmittance of 87% in the visible wavelength range. The performance of graphene-applied organic photovoltaic cell was enhanced by intermediating TiOX layer to yield an overall power conversion efficiency of 2.60% which is the higher efficiency among the efficiencies of photovoltaic cells with graphene electrodes. Our demonstration of highly efficient graphene-adopted photovoltaic cells may foster thrusting the fast-progressing graphene technology into the practical realm of organic photovoltaic cells.
