Electrical properties of dye sensitized solar cell with polyethylene glycol- based electrolyte and Senduduk fruit’s extract as photosensitizer

The study determined the electrical performance of dye sensitized solar cell by using electrolyte hydrogels of Polyethylene Glycol 4000 and Polyethylene Glycol 6000. The experimental work consisted of Dye Sensitized Solar Cell (DSSC) structure arrangement, assembly of DSSC layers, and measurement of DSSC. The resistances of TCO glass were 1.1 kΩ and 14.9 kΩ. The concentration of the thickening agents in the electrolyte solution were 5%, 10%, and 15%, and a control sample without the addition of hydrogel. The parameters included total anthocyanin content of senduduk fruit, voltage and current values, output and input power values, fill factor, and DSSC efficiency. The best DSSC performance was DSSC with the addition of PEG 6000 at a concentration of 15%, and its electrical characteristics were Isc: 0.0127 mA, Voc: 0.721 mV, Imax: 0.0102 mA, Vmax: 0.508 mV, Pmax: 0.00518 mW, FF: 0.5659, and an efficiency of 0.018%.
