Abstract

Dye Sensitized Solar Cell (DSSC) can convert solar energy into electrical energy using dye as a sensitizer. The dyes used in this study were chlorophyll from the extract of bungur leaves and anthocyanins from the extract of bungur flowers which were treated with various concentrations of 2, 4, 6, 8, and 10% in methanol solvent. The purpose of this study was to study the effect of different dye concentrations on the performance of DSSC. This research was conducted from October 2021 to February 2022 at the Biosystem Laboratory and Chemical Laboratory of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. The research method used is descriptive method with research stages including preparation of DSSC structure, DSSC preparation and assembly, and DSSC testing. The parameters observed were the chlorophyll content of the leaves and the anthocyanin of the curcas, the current and voltage, the power, the fill factor, and the efficiency of the DSSC. In the calculation of dye pigment levels, the highest chlorophyll content was found in the 10% concentration of bungur leaf sample, which was 7.16 mg/L, while the highest anthocyanin level was found in the 10% bungur flower sample, which was 0.58 mg/L. The highest efficiency value of the DSSC sample of bungur leaf is at a concentration of 8% of 0.0114%, with the value of the electrical performance produced is Isc : 0,0114 mA, Voc : 0,556 V, Imax : 0,0085 mA, Vmax : 0,440 V, Poutput : 0,00374 mW, and FF : 0,5901. In the flower DSSC sample, the highest efficiency is in the 10% concentration sample of 0.0151%, with the resulting electrical performance value is Isc : 0,0126 mA, Voc : 0,723 V, Imax : 0,0102 mA, Vmax : 0,528 V, Poutput : 0,00539 mW, and FF : 0,5912. Keywords: DSSC, efficiency, pigment content, electrical performance, dye concentration
