In the present course of work, we have successfully prepared a dye sensitized solar cell  (DSSC) based on TiO2 film coated ITO (indium doped tin oxide) glass photo anode, N719 dye as sensitizer, iodine as redox couple electrolytes and a counter electrode with graphite film coated ITO glass. Powder of TiO2 was synthesized by sol gel route technique. The XRD pattern confirms the anatase and rutile phase of TiO2. Crystallite size of TiO2 powder is 75.5nm. The TiO2 paste was coated on ITO by doctor blade technique. The FTIR spectrum shows a main peak corresponding to 495cm-1. However, UV-Visible absorbance of graphite/ITO glass and platinum/ITO glass were obtained as 20-25% and 7-17% respectively in the wavelength range of 300-800nm. The open circuit voltage of DSSC has been observed to be maximum 690.1mV and 619.5mV for platinum and graphite counter electrode respectively. The OCV decay shows the non linear nature. The fill factor values were obtained as 0.60 and 0.50 for platinum and graphite based electrode of DSSCs respectively. The efficiencies of DSSC with platinum/ITO and graphite/ITO electrodes were found to be 1.63% and 0.89% respectively.
