“…This study aims to analyze the optical properties and to know the electrical properties of the melinjo peel pigment consisting of 3 stages: the extraction of the melinjo peel pigment, the measurement of the absorption of the spectrum, and the measurement of the conductivity of the extraction results. The novelty of previous research conducted by Nurussaniah et al [12] is still in research using the method of deposition soak but in my research using the method of deposition drops and soaking.…”

It has been successfully identified and characterized by dye Melinjo peel (Gnetum gnemon) as an active material for Dye Sensitized Solar Cells (DSSC). The sample is formed in the structure of a working pair of electrode sandwiches and opposing electrodes. The dye extraction process (Dye) of the melinjo was stirred for 1 hour and then left to stand for 24 hours but there were only differences in how to doping dye into TiO2.Dye-sensitized solar cell (DSSC) is one of the photochemical electrical cells consisting of a photoelectrode, dye, electrolyte, and counter electrode. The purpose of using dyes in the DSSC is to extend the absorption spectrum to visible light because visible light has about 96% energy from sunlight. This article presents some experimental data on the nature of absorbance and the conductivity of natural dyes extracted from the plant as an application in the DSSC. Absorbance test using Spectrophotometer UV Visible 1601 PC and electrical properties test using Elkahfi 100 / Meter I-V. DSSC fabrication has been done using dye extract of melinjo (Gnetum gnemon) with a variety of immersion technique of drops and soak. The results show that natural dyes from natural material extraction have an absorbance spectrum of 380-520 nm range and the greatest conductivity is owned by melinjo (Gnetum gnemon). From the results of the test using AM Simulator 1.5G (100 mW / cm2) diesel simulator, it was found that the volume of TiO2 precursors affected the performance of DSSC solar cells and the overall conversion efficiency was 0.03% for the melinjo (Gnetum gnemon) dye by drops technique and 0.009% for the melinjo (Gnetum gnemon) dye by soak technique.

“…Photosensitizers can come from chlorophyll, carotene, anthocyanin, tannin, and flavonoid pigments obtained from plant parts, such as leaves, flowers, fruits, roots, stems, seeds, and skin [13]. One of the flowers that can be used as a photosensitizer is the butterfly pea (Clitoria ternatea), which has a characteristic single petal in blue, purple, white, and pink [14].…”

Stability is the main challenge in developing electrical energy made from sunlight, namely Dye-Sensitized Solar Cell (DSSC). The DSSC system comprises a photoanode, electrolyte, comparison electrode, and dye sensitizer with a photoelectrochemical working principle. Dye sensitizer and electrolyte are the main components that determine the stability of DSSC, with problems such as solvent evaporation leakage in liquid electrolytes and dye desorption. In overcoming these problems, the polymer electrolyte of Polysulfone/Polyethylene Glycol (PSf/PEG) is a solution to the problem by increasing the mobility of I-/I3- ions in the electrolyte. Polymer composition and porogen (pore formers) affect the ionic conductivity, which impacts the electron flow of the DSSC system. Therefore, this study optimized the composition of PSf/PEG polymer electrolyte, namely 18/0, 17/1, 16/2, 15/3, 14/4, and 13/5. This research was carried out using quantitative methods with data processed in a quantitative descriptive manner to determine the performance of DSSC based on PSf/PEG membrane electrolyte. The wavelength absorption of the dye was characterized using a Spectrophotometer UV-Vis instrument, and the specific wavelength was obtained at 573 nm, which indicates anthocyanin absorption. Electrochemical characterization of the dye using voltammetry yielded a resulting energy bandgap value of 0.5132 eV with the touch plot method. Testing the performance and stability of DSSC, voltage, and current measurements were carried out using a multimeter, and fill factor and efficiency calculations were carried out. The performance of DSSC with liquid electrolytes was 1.66%, while that of DSSC with membrane electrolytes of the best composition (16/2) was 1.38% at 0 hours. In addition, the performance test was carried out at 72 hours of exposure time, resulting in an efficiency of 0.77%, while the DSSC with the best composition of membrane electrolyte (16/2) was 1.11%. This shows a decrease in the efficiency of DSSC with liquid electrolytes by 53.43%, while the membrane electrolyte efficiency of DSSC is 19.33-20.17%.
