The past two decades Titanium Dioxide (TiO2) based Dye sensitized solar cells (DSSC) has received more and more attentions from academia and industry because it is widely studied material for the safe and reliable energy supply due to its low fabrication cost, eco-friendly production and competitive efficiency. The present review deals with recent advances made through the semiconductor nanoparticles sensitization on well aligned DSSC, which is combining to form a photo conversion device, are the conducting substrate, dye, photo anode, catalyst and electrolyte. Among this various component photo anode is probability the main component which determines the energy conversion efficiency and TiO2 is widely recognized component for photo anode from the researchers. This review also deals with the efficient fabricate methods for TiO2 preparation and characterization to improve the efficiency of TiO2 photo anode for DSSC. Here reviewed photoelectric conversion efficiency of DSSC has exceeded 11% for cell using TiO2 but still it is two times lower than silicon cell technology. To overcome this limitation, the vast research studies developed highly efficient DSSCs by the material break through and have a current record of 15% efficiency.
