For efficient charge injection and transportation, wide band gap nanostructured metal oxide semiconductor with dye adsorption surface and higher electron mobility are essential for photoanode in dye sensitized solar cells (DSSCs). In this study, TiO2 films with anatase phase are prepared by using simple precipitation-annealing followed by cost effective Doctor’s Blade method with titanium tetraisopropoxide as Ti-precursor. The influence of annealing temperature on structural, morphological, optical and photovoltaic properties is systematically investigated. The XRD and Raman spectroscopy characterization studies revealed the formation of pure single anatase phase TiO2 in resultant films. The better optical properties: indirect band gap, absorbance coefficient and transmittance are found to be 3.19 eV, 1.70 x 104/cm and 65.4 % respectively in resultant films. The better photovoltaic performance: open circuit voltage (Voc) = 0.564 V, current density (Jsc) = 4.80 mA/cm2, fill factor (FF) = 42.57 % and photo conversion efficiency = 1.03 % using Eosin-Y dye with polyiodide electrolyte is obtained for DSSC of nanocrystalline TiO2 films obtained at 400 oC
