Abstract

The dye-sensitised solar cell is a photoelectrochemical-based solar cell that uses a natural dye as the photosensitizer and an electrolyte as the charge transport medium. The volatility of the electrolyte is one of the causes of instability; therefore, a thickening agent was added to reduce the volatility. The aim of this study was to determine the electrical performance of a dye-sensitised solar cell using an extract of water hyacinth leaves as a photosensitizer and xanthan gum (XG) as a thickening agent in the electrolyte. Extraction of the dye from water hyacinth leaves using ultrasonic waves and deposition of TiO2 films on TCO using the squeegee method. The extracted dye contained 10.74 mg/L chlorophyll. The concentrations of XG were 1, 3 and 5 % (w/v). The highest efficiency (0.017%) was found with the addition of 5% GX, with the electrical output of Voc 0.721 V, Isc 0.0127 mA, Vmax 0.508 V, Imax 0.0102 mA, Pinput 29.7 mW, Poutput 0.005182 mV, FF 0.56588.
