In this paper, the photoanode of dye-sensitized solar cell (DSSC) was fabricated as a double layer structure, where graphene oxide (GO) was incorporated with titanium dioxide (TiO2) film onto the ZnO compact layer. The photovoltaic characteristics, crystal structures, morphologies, and electrochemical impedance were investigated. According to the experimental results, the photovoltaic performance of DSSC was improved with the modification of ZnO compact layer and GO. The phenomenon can be attributed to the higher specific surface area of GO and the property of forming an energy barrier between the substrate and TiO2 film for ZnO compact layer, which can inhibit the electron-hole recombination.
