Studies on the energy conversion of solar cells using pigments extracted from plants that grow in Ecuador which show good potential for these purposes

This project aims to continue research on dye-sensitized solar cells (DSSCs), also known as Grätzel cells, utilizing natural pigments extracted from Ecuadorian plants. The main objective is to optimize the energy conversion efficiency of these cells, building upon the manufacturing and characterization methodology established in a previous phase. DSSCs are attractive due to their low cost, ease of fabrication, and aesthetic qualities, mimicking photosynthesis. The proposed methodology includes an exhaustive literature review and experimental trials focused on the optimized deposition of titanium dioxide (TiO2) thin films onto conductive glass (FTO). Optical and electrical characterization will be performed on the films and the adsorbed pigments, including tests on adsorption time and different extraction solvents. Finally, the optimized cells will be assembled and electrically characterized to evaluate the impact of the implemented improvements on energy efficiency.<br/><br/><b>Goal</b>: <br/>To improve the energy conversion efficiency of solar cells sensitized by natural pigments extracted from Ecuadorian plants, optimizing the various manufacturing possibilities established in the project's baseline.<br/><br/><b>Research lines</b>: <br/>Solid waste and optimization of renewable energies
