Highly　ordered　titanium　dioxide　(TiO2)　nanotube　films　have　been　fabricated　using　anodic　oxidation　at　different　voltages　(10　V　to　70　V).　The　morphology,　specific　surface　area,　light　absorbance　capability　and　conductivity　of　the　obtained　films　have　been　investigated.　The　anodized　voltage　was　found　to　have　a　crucial　influence　on　the　morphology,　light　absorb　capability　and　photo-electrochemical　properties　of　the　anodized　nanotube　films.　The　diameter　of　the　nanotube　increases　linearly　with　the　applied　voltage.　The　nanotube　film　anodized　at　30　V　has　the　highest　BET　(Brunauer-Emmett-Teller)　surface　area,　much　more　quantity　of　coated　sensitizer　N719,　and　the　smallest　resistance　for　dye　sensitized　solar　cells　(DSSC).　Back　side　illuminated　DSSC　were　assembled　using　these　as-anodized　nanotube　films.　Pt　FTO,　which　has　a　transmittance　of　about　50%,　served　as　counter　electrode.　The　best　device　based　on　nanotube　films　performed　at　30　V　gives　a　highest　power　conversion　efficiency　of　1.87%,　with　a　photocurrent　density　(J(sc))　of　6.70　mA/cm(2)　and　open　circuit　voltage　(V-oc)　of　0.57　V.
