Abstract

A natural grape juice has been extracted from grape fruits, purified and successfully applied as a dye on nanocrystalline TiO₂ photoelectrode for the fabrication of dye-sensitized solar cell (DSC). The KI/I₂ based electrolyte and carbon counter electrode were the other components in this DSC. The extracted grape-dye showed much similar photovoltaic performance to the previously studied natural dyes. The photoelectric conversion efficiency of 0.4 % (photocurrent density, JSC = 1.71 mA/cm²; open circuit voltage, Voc = 0.516 V, fill factor, FF = 46%) was achieved under irradiation with 100 mW/cm² white light. in price.
