The influence of mixing amount of carbon black on electrical and electrochemical properties of TiO2/graphite blend film was studied. Morphologies,electrical properties and electrochemical properties of electrodes were characterized by scanning electron microscopy,four probe method and electrochemical impedance spectroscopy,respectively. Photovoltaic performance of the cells was examined. It is found that the sheet resistance of carbon counter electrode decreases by 35% with incorporation of carbon black. When carbon black content is 5%(mass fraction),charge transfer resistance and photovoltaic performance reach the optimum. Photoelectric conversion efficiency reaches 74% of the cells with Pt counter electrode.
