TiO2 films were prepared on FTO glass using the sol-gel process for a dye-sensitized solar cell application. The TiO2 sol was prepared by the hydrolysis/polycondensation. Titanium tetraispropoxide was used as a precursor, and Nitric acid (HNO3) was used as a catalyst for the peptisation. The crystalline and particle sizes were controlled by adjusting the catalyst concentration and the calcination temperature. The crystal structure and morphology were measured by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The TiO2 sol calcinated at low temperatures had an anatase phase, and they were grown rutile phase increased as calcination temperature. The properties of the TiO2 sol was adjusted by a concentration of catalyst. The prepared TiO2 sol were coated on FTO glass by spin coating method. The transmittance of the TiO2 films was investigated.
