Abstract
This study evaluates the photovoltaic performance of Dye-Sensitized Solar Cells (DSSCs) for varied light conditions. The focus of this work is on exploring the experimental characteristics of a thin-film solar cell composed of ITO/TiO2/N3 Dye and BMII electrolyte molecules/Pt/ITO. A meticulous investigation is conducted to understand the impact of different illumination intensities on the efficiency of these solar cells. In the experiments, the power conversion efficiencies (PCE) of the device reached 7.61 % with a maximum open-circuit voltage (Voc) of 0.67 V under 100 mW/cm2 AM 1.5 solar irradiance. The morphology of the TiO2 nanopArticles that have been synthesized for the DSSC were analyzed by Ultraviolet-visible Spectrometry, X-Ray Diffractometry, as well as Scanning Electron Microscopy and Atomic Force Microscopy investigations. Electrochemical impedance spectroscopy (EIS) parameters and Nyquist plot showed that charge transfer and DSSC are important for the equivalent circuit structure. The results of this study allow optimizing the performance of future DSSCs for sustainable energy systems.
