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.

Abstract

Firdaus, M., Tamrin, T., Ramadhani, I. S, & Pratama, F. (2025). The Combination of Senduduk Fruit (Melastoma malabathricum) and Telang Flower (Clitoria ternatea) in Dye Sensitized Solar Cells. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Dye Sensitized Solar Cell is a solar cell technology composed of a TiO₂ semiconductor, dye as a light absorber, an electrolyte as an electron donor, and a counter electrode, arranged in a sandwich-like structure. One of the main factors influencing the efficiency of DSSC is the type of dye used, as each dye can only absorb light within a specific wavelength range. This limitation can be overcome by mixing two or more types of dye with different absorption spectra, thereby broadening the light absorption range and enhancing the performance of the solar cell. This study aimed to investigate the effect of combining natural dyes derived from anthocyanins in senduduk fruit and butterfly pea flower at various ratios 1:1, 1:3, and 3:1 on DSSC efficiency. The research process consists of three main stages: DSSC structure preparation, DSSC layer assembly, and electrical characteristic measurements. The observed parameters include the generated voltage and current, maximum power output, Fill factor, and cell efficiency. The results show that the use of mixed dyes yields better performance than a single dye, with the best result achieved at a 1:3 ratio, producing Voc of 611 mV, Isc of 67,7 µA, Vmax of 275 mV, Imax of 0.0547 mA, Pmax of 15,0425 µW, and an efficiency of 0.0541%.

Abstract

Etria, E., Tamrin, T., Ramadhani, I. S., & Pratama, F. (2025). The use of Parchment Paper as an Electrolyte Absorption Medium to Enhance the Efficiency of Dye-Sensitized Solar Cells. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This paper aimed to study the addition of parchment paper layers as an electrolyte absorbent medium to achieve maximum efficiency of dye-sensitized solar cells (DSSC). Dye-sensitized solar cells are environmentally friendly, but still face challenges with the stability of liquid electrolytes, which easily evaporate. To address this issue, an innovation was carried out by adding parchment paper layers, which have relatively water-resistant characteristics and are able to gradually absorb liquids. The research was conducted using variations of one to six parchment paper layers. The results showed that the highest efficiency was achieved with the use of five parchment paper layers, reaching 0.0797%. The addition of layers increased electrolyte absorption and stability up to the optimal number of layers. However, excessive layering reduced efficiency due to ion transfer resistance. In conclusion, the addition of parchment paper layers can improve DSSC efficiency up to a certain number of layers (five layers) and has potential as an effective electrolyte retention solution.

Abstract

Hasimi, I., Tamrin, T., Ramadhani, I. S., & Pratama, F. (2025). The Variation of Fiber tissue Hole Area as an Electrolyte Absorption Medium in Dye Sensitized Solar Cell. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Dye sensitized solar cell (DSSC) is a third-generation solar cell based on photoelectrochemical processes that can convert solar energy into electrical energy with the help of a sensitized as a light absorber and TiO₂ as a charge separator.  The electrolyte is one of the components of DSSC in the form of a liquid containing an iodide/triiodide redox couple.  A weakness of DSSC is that the electrolyte easily evaporates, resulting in low performance and durability.  The addition of a fiber tissue layer between the working electrode and the counter electrode as an absorbent medium can reduce the evaporation rate of the electrolyte and improve the performance of the DSSC. This study aimed to investigate the performance of DSSC with the addition of a fiber tissue layer with varying hole sizes as an electrolyte-absorbing medium.  The research consisted of three stages: DSSC structure preparation, DSSC layer arrangement and assembly, and DSSC measurement.  The fiber tissue added in this study has square holes with varying sizes: 0 cm × 0 cm, 0.5 cm × 0.5 cm, 0.75 cm × 0.75 cm, 1 cm × 1 cm, 1.25 cm × 1.25 cm, 1.5 cm × 1.5 cm, and a control sample without fiber tissue.  The parameters observed in this study include current and voltage characteristics, power calculation, fill factor, and DSSC efficiency.  Based on the results, DSSCs with fiber tissue layers of varying hole sizes generally showed better performance compared to the control DSSC.  The best performance was obtained from the DSSC with a fiber tissue layer having 1 cm × 1 cm hole size.  The electrical characteristics obtained were: Voc: 608 mV, Isc: 96,4 µA, Vmax: 288 mV, Imax: 0.0634 mA, Pmax: 18,26 µW, Fill factor (FF): 0.3115, and Efficiency: 0.0673%.
