In the present study, irregular needle-like TiO₂ nanotubes developed through anodization on Ti layer substrate deposited on the FTO by sputtering method and also TiO₂ nanoparticles coated by Dr.blade method which was deposited on the FTO were compared in the form off dye-sensetive solar cells (DSSCS). Ti deposition process was carried out by sputtering method for 6 hours for deposition of 2.200 µ thickness on FTO. Next Tio2 nanotube developed through anodiztion in 120 V voltage to produce irregular needle-like nanotube pattern. Then anodized samples were annealed in 450℃ temperature. Also Tio2 nanoparticle deposited on FTO by Dr.Blade method, weree annealed in final 550℃ temperature after several heating. In this research XRD, AFM and SEM analysis were used to evaluate thee samples.
