The paper reports on the fabrication and characterization of dye sensitized solar cells using
ruthenium-stained and chlorine-stained titanium (iv) oxide. Copper metallated semisynthetic
chlorine dye was extracted from bahama grass. Thin films of ruthenium-stained and
chlorine-stained TiO2 were deposited on transparent conducting oxide glass using the blade method. Both electrodes were found to absorb solar radiation both in the UV and VIS region, but
the ruthenium-stained electrode showed a higher optical absorbance. The photoelectric energy
conversion efficiency was found to be 1.7% and 1.0% for the ruthenium and chlorine-stained
electrodes, respectively. The efficiency of the ruthenium-stained cell can be compared with
1.43% obtained by Suri et al.; 1.49%, 2.56%, and 3.26% obtained by Waita et al. and 1.5%
recorded by Law et al. The lower conversion efficiency of the chlorine-stained solar cell could be
attributed to lower injection efficiency due to less optical absorption. The values of maximum
power output obtained for the three days show that the local dye can make a good photo-
sensitizer but would require further treatment to improve on its optical absorbance and stability
under exposure to solar irradiation.
