This study focused on extracting natural dyes from fruits for use in Dye-sensitized solar cells (DSSC). Among the four dyes studied, ber dye showed the highest solar cell efficiency, making it a promising candidate for eco-friendly and cost-effective DSSC development.
Four natural dyes were extracted from different fruits used in the Dye-sensitized solar cell (DSSC). It includes ber, blackberry, black grapes, and blueberry by individual dye or combined with other dyes. The dye solution's absorption spectra were extended to the whole visible region 200-750 nm. FTIR spectroscopy was employed to identify the possible functional group vibrations responsible for the dyes' chemical activity and optical behaviour. The TIO2 powder was coated on the ITO conducting surface to form a thin film. The experimental results showed that the ber dye produces the highest solar cell efficiency (eta), (similar to)13%, among all four extracted anthocyanin studied. It also found that ber combination with other dyes is higher conversion efficiency than blackberry, black grapes, and blueberry with another and vice versa. Ber dye can be helpful in the development of more eco-friendly and cost-effective solar cells with commercially promising DSSC.
