Abstract

Nanostructured TiO2 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.
