Efficient TiO₂ nanoparticle-ruthenium sensitizers with high open-circuit voltage (Voc) for high-performance dye-sensitized solar cells

Abstract

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.

“…The UV-Vis spectrum is very useful for quantitative measurements. The concentration of the analyte in the solution can be determined by measuring the absorbance at a certain wavelength using the Lambert-Beer law [24].…”
