The 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 mangosteen skin pigment (Garcinia mangostana) with a variety of coating technique of Spin Coating and Slip Casting. 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 mangosteen fruit skin pigment (Garcinia mangostana). 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 0.084% for the mangosteen skin dye by slip casting technique and 0.092% for the mangosteen skin dye by spin coating technique.
The study aims to characterize Ruthenium as a photosensitizer in Dye-Sensitized Solar Cells (DSSC). Samples are made in the structure of the working electrode pair Sandwich and the opponent electrode. Sample absorbance test using UV-Visible LAMBDA 25 spectrophotometer and test current and voltage characterization (I-V) using Keithley 2602A. The results of the study showed that the maximum absorbance in the high dye ruthenium appeared at the two peaks at 448 nm and 580 nm. While I-V curve measurements showed great efficiency that resulted in ruthenium dye with concentrations of 0.1, 0.5, and 1 in a row were 0, 12%, 0.186%, and 0.26%. These results show that higher concentrations of ruthenium dye can increase the value of the resulting efficiency.
Energy derived from fossils is diminishing and cannot be renewed. Therefore many experts are looking for other alternatives to create new renewable energy, and Dye-sensitized solar cells (DSSC) are one of them. This study aims to know the characterization of the electrical properties of dye cosmos caudatus material. The research was conducted at the UNS FMIPA Materials Laboratory. This research uses the TiO2 deposition method with the spin coating technique. Absorbance test using PC UV Visible Spectrophotometer 1601 and Current and voltage test (I-V) using Keithley. The efficiency produced by the Cosmos caudatus chlorophyll dye was 8.3 × 10−3 %. These results show that some natural dyes from natural organic material extraction have an absorbance spectrum range of 300-800 nm, which has the potential as DSSC.
