Recently, dye-sensitized solar cells based on natural pigments have been demonstrated. The performance of anthocyanin local dye as photosensitizer for dye-sensitized solar cell has been successfully studied. Anthocyanin dye is an extract from hibiscus sabdariffa which is an edible plant called zobo by Nigerians. Anthocyanin-stained TiO2 electrode showed an outstanding optical absorbance within wavelength range of 283 nm – 516 nm. Peak absorbance of 2.16A.U. 2.26A.U. and 2.38A.U. were recorded in the UV region at 324.45nm, 344.87nm and 369.35nm respectively. Appreciable absorbance was recorded in the visible region with two outstanding peaks; 2.26A.U. and 2.16A.U., occurring at 405.99nm and 426.47nm respectively. The photovoltaic parameters of a second cell fabricated with unstained TiO2 photo-electrode was studied for comparison of results. The overall conversion efficiency of the stained and unstained cells were 0.58% and 0.03% respectively. Copyright@ International Science Community Association
