TiOZ nanorods have large specific surface area and the ability of directional transmission electron，based on which can reduce recombination probability of light-generated electrons and holes，and improve thephotoelectric conversion efficiency of DSSC. As graphene has low resistivity，good stability and excellenttransparency，it can be introduced into anode film to improve the electronic transmission. The TiOZ nanorods wereprepared by hydrothermal method，mixed with different quality of graphene. Its length range was 200-300 nm，witha diameter of about 20 nm. The porous graphene/TiOZ nanorods composite film were prepared by using electro-hydrodynamic technique(EHD)and compositing TiOZ nanorods with different quality of grapheme. Thephotoelectric conversion efficiency of the DSSC device prepared with the photo-anode film with graphene masscontent of 3 % was 4. 23 %，the photoelectric conversion efficiency increased by 36%，relative to that of nographene doped TiOZ nanorods photo-anode film.
