Aligned  Rutile  TiO2  nanorods  (r-TNRs)  and  TiO2  nanoflowers  (r-TNFs)  were  successfully  prepared  by  hydrothermal method. Using hydrochloric acid (HCl) as chelating agent and titanium butoxide (TBOT) as precursor, aligned r-TNRs with r-TNFs were successfully growth onto fluorine-doped tin oxide (FTO) with different morphologies. The influences of surface morphologies to the rutile based Dye-sensitized solar cell (DSC) efficiency are discussed. The highest light-to-electric  energy  conversion efficiency,  1.80%  is  achieved  using  different  concentration  under  simulated  solar  light illumination of 100 mWcm-2 (1.5 AM).
