Paper Abstract

A study on dye-sensitized solar cells (DSSCs) with extracts of Syzygium guineense as sensitizer is reported for the first time. DSSCs were assembled using natural dye extracted from Syzygium guineense as sensitizer. The photoelectrochemical performance of the quasi-solid state DSSCs based on the ethanol extract dye showed VOC of 0.506 V and JSC of 2.03  mAcm−2; and a power conversion efficiency of 0.51%. UV-vis spectroscopy studies of light absorption of the natural dye were done. Furthermore, the ethanol extract obtained from Syzygium guineense was further purified stepwise through solvent-solvent extraction. The photoelectrochemical performance for the extracts with different solvents indicated that the individual components have synergistic effect in the performance of the DSSC.
