Design and development of dye-sensitized organic semi conductor based photo electric system utilizing nanotechnology for low cost and efficient conversion of solar energy to electricity

Abstract

Preliminary investigations on the identification of natural pigments in the dye-sensitization of Nano crystalline n-type TiO2 were carried out. Fresh extracts of Mangoostein, Rabutan, Mango, Tomato, Carrot, King coconut, Pumpkin, Red Bannana, and Beet root were employed as sensitizers in thin-layer sandwich-type photoelectrochemical solar cells. The dye extract obtained from the Mangoostein fruit showed better performances than the others.
