Abstract: Nanostructured TiO$_2$ thin films were prepared for various thicknesses on fluorine – doped tin oxide (FTO) conductive glass by the spin coating method. Anthocyanin dye was used to sensitize the sample. The structural characterization was done by XRD. The bandgaps from UV-Vis and photoluminescence measurements are in the range of 2.41 to 2.59 eV. The photocurrent and photovoltage of the cells was measured using Keithley source meter. A maximum conversion efficiency of 0.27 % was observed and the results were discussed.

Keywords: Dye sensitized solar cells, natural dyes, TiO$_2$ film.
