Abstract

Dye Sensitized Solar Cell is a set of photoelectrochemical-based solar cells that can convert solar energy into electrical energy by utilizing plant-derived dyes as a sensitizer. One of factor that can affect the performance of a DSSC is the fast drying of electrolyte; therefore, thickening agents of xhantan and arabic gums were added in the electrolyte to slow down the evaporation of electrolyte. The electrolyte solution used in this study was iodine with a concentration of 0.1 N and thickening agents of xhantan and arabic gums. This study aimed to determine the performance of Dye Sensitized Solar Cell with Water Hyacinth Leaf Extract as a Light Sensitizer with the addition of Xhantan Gum and Gum Arabic. This research was carried out from March 2022 to August 2022 at the Energy Electrification Laboratory and Chemical Laboratory of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. This study consisted of three stages, namely DSSC structure, arrangement and assembly of DSSC layers, and measurement of DSSC. The TCO glass used has a resistance between 0.9 Ω to 15.1 Ω DSSC. The concentration of thickening agents in the electrolyte solution were 1%, 3%, 5% and control samples without concentration. The parameters observed in this study were the measurement of chlorophyll absorbance at 649 nm and 665 nm wavelenght, current and voltage, power calculation, fill factor, and DSSC efficiency. The best DSSC performance was using water hyacinth dye with the addition of a thickening agent in the xhantan gum electrolyte solution is a thickening agent concentration of 5%. The electrical characteristics generated in the sample are Isc: 0.0138 mA, Voc: 0.743 mV, Imax: 0.0103 mA, Vmax: 0.519 mV, Pmax: 0.00535 mW, FF: 0.5214, and an efficiency of 0. 0185%.
