Abstract |
| Dye-sensitized solar cell fabrication procedure has been employed using natural dye extracts from Mucuna flagellipes and Zeamaize comb as natural sensitizer of TiO2 films. The dye yielding materials were dried to invariant weight in the laboratory and the dye extracted using simple laboratory technique. Photovoltages and photocurrents of 0.11 and 0.25mV, 6.44 and 5.34mA were obtained for Mucuna flagellipes and Zeamaize comb dye extracts, respectively. Similarly, overall solar energy conversion efficiencies and fill factors of these cells obtained Am1.5 under irradiation were 0.33 and 0.47 0.43 and 0.32 for Mucuna flagellipes and Zeamaize comb dye extracts, respectively. Among the natural dye sensitizers studied, the Zeamaize comb gave the best photosensitizing effect which can be used as an environmental friendly low cost alternative solar power conversion system.
