This study investigates the enhancement of efficiency in dye-sensitized solar cells (DSSCs) through the addition of an oxidizing agent to the TiO2 paste used in the fabrication of the working electrode. The objective is to address the adverse effects of residual carbon from organic binders, which limits dye molecule adsorption and thereby reduces light absorption and energy conversion efficiency. The methodology involves the analysis of the influence of UVO3 treatment of TiO2 films on the efficiency of DSSCs. Results indicate a significant 10% increase in cell efficiency with UVO3-treated TiO2 in comparison to untreated samples, despite a reduction in open-circuit voltage. This finding underlines the importance of the electronic structure of TiO2 films in optimizing solar cell performance, and indicates that the reduction of organic residues can effectively enhance the light harvesting capabilities of DSSCs. By mitigating the limiting factors associated with TiO2 film preparation, this approach holds potential for advancing the practical application of dye-sensitized solar cells in renewable energy technologies.
