DSSCs were fabricated using conventionally prepared and pre dye treated Tio2 sensitized successfully with the new natural dye rich in xanthophyll pigment. The light to electron conversion efficiency of conventionally prepared TiO2 based DSSC is 0.49% and the efficiency is significantly improved to 1.05% in pre dye treated Tio2 based DSSC. The modified sol-gel process yielding pre dye treated TiO2 nano particles is a promising methodology in terms of more dye adsorption, less dye aggregation and improved And the natural dye extract of P marsupium stem bark is a potential dye sensitizer for environmental friendly DSscs for harvesting solar energy. Therefore, this can be effectively adopted for the fabrication of DSSCs with higher efficiency
