Analysis of Natural Sensitizers to Enhance the Efficiency in Dye Sensitized Solar Cell

By S.Rajkumar and K.Suguna


Three vegetable dyes are used for the study: anthocyanin dye from pomegranate arils extract, betalain dye from\ud beet root extract and chlorophyll dye from tridax procumbens leaf. The anthocyanin and betalain, anthocyanin\ud and chlorophyll, betalain and chlorophyll dyes are blended in cocktail in equal proportions, by volume. This\ud study determines the effect of different extraction concentrations and different vegetable dyes on energy gap\ud using dye sensitized solar cells. The experimental results show that the cocktail dye blended using extracts of\ud pomegranate arils, beet root and tridax procumbens leaf, in the volumetric proportion 1:1, using an extraction at\ud room temperature the greatest energy gap (eg) of up to 1.87eV
