Abstract: (7085 Views)
In this study by using sol-gel Pechini method, the nano-porous TiO2 layer was fabricated as a photoanode of dye sensitized solar cell. In this method by adding TiO2 nanoparticles to sol that obtained by mixing citric acid, ethylenglycol and titanium alkoxide, TiO2 paste was obtained and this layer was applied by doctor-blade method on a conductive substrate. I-V curve of the cell was measured under the Xenon lamp irradiation. The results of this cell were compared with the results of cell obtained from TiO2 layer that was made by conventional method and significant improvement was observed in the pechini cell behavior. Also it was observed that by increasing the TiO2 of the paste the wettability of paste was improved.
