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

Saputri, R. A., Prayoga, A., Ramadhani, I. S., Pratama, F., & Tamrin, T. (2024). Evaluation of dye sensitized solar cells performance with continuous fiber tissue layer. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 344–357).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the factors that can affect DSSC performance are electrolytes. The addition of continuous fiber tissue can improve DSSC performance by maintaining electron continuity because electrolytes are always available. The fiber tissue used in this study was facial tissue. This research was studied the differences in the width of the continuous fiber tissue layer as an electrolyte provider on the performance of dye sensitized solar cells, especially efficiency and fill factor. This study used several series, namely: preparation of the DSSC structure, arrangement and assembly of the DSSC layer, and measurement of the DSSC. The variations in the width of the continuous fiber tissue layer used in this study were 1 cm, 1,5 cm, and 2 cm. The research parameters observed in this study were: current and voltage measurements, power calculations, Fill Factor measurements, and DSSC efficiency calculations. The results of the study showed that the performance of DSSC with the addition of continuous fiber tissue layers with variations in width had higher performance than DSSC without additional treatment. The best DSSC performance using the addition of continuous fiber tissue was found in experimental unit B with a width of 1,5 cm, namely Isc: 0,0269 mA, Voc: 731 mV, Imax: 0,0103 mA, Vmax: 472 mV, Pmax: 5,0504 µW, FF: 0,257, and an efficiency of 0,01912%.
