Abstract: In present work indium Tin oxide/titanium Dioxide (ITO/TiO2) based thin films prepared on glass substrate by chemical spray pyrolysis (CSP) method at 300 oC, 350 oC, 400 oC and 450 oC annealing temperatures. From X-ray diffraction (XRD) the amorphous and crystalline nature of ITO/TiO2 structure was analysed at all the temperatures. As the grain size becomes larger, indirectly it develops the crystalline quality of the TiO2 films studied from Atomic Force Microscopy (AFM). The surface of TiO2 films and the crystallite size of the sample are increased gradually with respect to temperature which is observed in Scanning electron microscopy (SEM). The elemental compositions of thin films are determined by the energy dispersive analysis of X-ray (EDAX) showed that TiO2 thin films were highly stoichiometric. The TiO2 is promising material for relatively low cost; manufacturing is so simple and high-efficiency in present generation of solar cells. In dye-sensitized solar cells (DSSCs) the presence of a TiO2 is necessary to avoid short circuits in between electrodes, this layer determines by fact that compared with surface having in flat, the DSSCs absorbent surface area is increase the absorption and hence conduct to the rise of solar cells performance. In this paper we are presented samples by using spray method and ITO/TiO2 structure was investigated, and deferent annealing measurements are acted and showed most useful differences in between annealing temperatures (300 oC, 350 oC, 400 oC and 450 oC). And the noise is also affected the efficiency of the cells, the 1/f noise analyses are achieving the impartiality at all the samples, the results proved that this work is most useful for recent trend of solar cell applications.
