In the present investigation, TiO2 nanotube arrays were grown on the Titanium (Ti) films deposited on transparent conducting FTO (fluorine doped tin oxide) glasses for the application of dye sensitized solar cells (DSSCs). Highly adhesive Ti films were deposited on FTO substrates using the sputtering technique with the thickness of about 2.200 &mum at the sputtering durations of 6 h.Subsequently, TiO2 nanotubes were fabricated on the sputtered Ti film by the electrochemical anodization method at an anodization voltage of 60 V for design Vertical array nanotubes and 120 V design Grass .after annealing at 450 °C. Difference in surface morphology by AFM images and SEM images were taken.
