Abstract

Azra, M. R., Tamrin, T., Pratama, F., & Ramadhani, I. S. (2024). Efficiency evaluation of dye sensitized solar cell through the use of PEG electrolyte hydrogel and water hyacinth leaf extract dye. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 426–433).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The research that has been conducted is a study of the effect of the Use of PEG electrolyte hydrogels on the performance of Dye Sensitized Solar Cells with water hyacinth leaf dye extract. This research aimed to study and determine the performance of dye sensitized solar cells using a variety of electrolyte hydrogels based on PEG 4000 and PEG 6000 with concentrations of 5%, 10% and 15% respectively. This study measured the absorbance of water hyacinth leaf dyes using a UV-VIS spectrophotometer and to determine the performance DSSC itself measured using a multimeter which was carried out with a light source of the halogen lamp. The parameters observed in this study dye absorption, current and voltage, power calculation, fill factor, and DSSC efficiency. The results showed that the use of PEG-based electrolyte hydrogels in DSSC can increase the efficiency and stability of DSSC use. The best DSSC performance using water hyacinth dye extract with the use of PEG-based electrolyte hydrogel occurred in DSSC G with 15% PEG 6000. The electrical characters produced on the sample are Isc: 0.0133 mA, Voc: 0.698 mV, Imax: 0.0073 mA, Vmax: 0.534 mV, Pmax: 0.003898 mW, FF: 0.62856, and efficiency of 0.021%.

Abstract

Dye-sensitized solar cells (DSSC) are third-generation photovoltaic devices capable of using natural pigments as photosensitizers. This study aims to optimize the efficiency of DSSC by using formulations of a combination of natural dyes extracted from swamp vegetation: water hyacinth (Eichhornia crassipes), senduduk fruit (Melastoma malabathricum), and primrose willow (Ludwigia peruviana). These dyes, which are rich in chlorophyll, anthocyanins, and carotenoids, respectively, were formulated in different volume combinations using the Simplex Lattice Design (SLD) method. The experimental results show that the mixture of natural dyes can expand the absorption range of visible light wavelengths and enhance the performance of DSSC. The optimal dye combination, consisting of 1.827 mL water hyacinth and 3.173 mL senduduk fruit, yielded an efficiency of 0.050% with a desirability score of 1. This study highlights the potential of swamp vegetation as a sustainable and low-cost alternative for DSSC applications and demonstrates the effective use of statistical modeling to optimize dye formulations.
