Abstract
ABSTRACTIn this paper, two efficient dye-sensitized solar cells (DSSCs) are prepared using natural dyes extracted from Acalypha Godseffia and Epipremnum Aureum plant leaves. Characterization of these two dyes using UV visible spectroscopy and the study on surface morphology of ITO plates coated with dyes is carried out. DSSC prepared with a dye extracted from Epipremnum Aureum under standard irradiation conditions showed the electrical characteristics: VOC = 0.77 V, JSC = 7.58 A/cm2, Jm = 6 mA/cm2, Vm = 0.56 V, ff = 0.576, and ɳ = 3.362%. The extract from Acalypha Godseffia showed interesting performance: VOC = 0.77 V, JSC = 9.21 mA/cm2, Jm = 7.95 mA/cm2, Vm = 0.55 V, ff = 0.61656, and ɳ = 4.372%.
