Four natural dyes obtained from Bixa orellana, Pterocarpus erinaceus, Sorghum candatum, and Zingber officinale, were used as dye-sensitizers in TiO2 coated plate of a dye sensitized solar cell. The natural dyes actually act as sensitizers. The movement of the electrons across the conduction band of TiO2 electrode produced a potential difference across the plates with an open circuit voltage (Voc) range from 0.2 -0.6 V, and photocurrent 1.7mA recorded. At the introduction of a series resistor of 10 W, the short-circuit voltage and current ranging from 0.18 - 0.56V and 0.06-0.13 mA respectively were obtained for the dyes. The use of mordant (CuSO4) increases the active period of the dyes for more detail measurements. Dye from Bixa orellana gave the best result.
