Study and construction of Grätzel-type solar cells with natural pigments extracted in Ecuador

This project focuses on the development and characterization of Dye-Sensitized Solar Cells (DSSC), a fourth-generation photovoltaic technology, as a viable alternative to conventional silicon cells whose costs remain high. The main focus is the substitution of expensive synthetic pigments (Ruthenium-based) with natural pigments sourced from local Ecuadorian plants, leveraging the hybrid (organic/inorganic) nature of DSSCs and their reasonably priced materials. The methodology involves literature review, material acquisition, and detailed cell construction. Electrodes will be prepared by depositing TiO2 films (using P25, PEG, and ethanol) onto FTO glass substrates, employing deposition techniques such as electrophoresis and pressure deposition. The counter-electrode will be prepared with a thin layer of Platinum (Pt). Finally, the cells will be assembled, the electrolyte (I3-/I2) injected under vacuum, and their performance characterized through current-voltage measurements under simulated sunlight. The resulting data will allow for the characterization of the natural pigment cell functionality and establish the groundwork for optimizing and adapting this technology to the Ecuadorian context.<br/><br/><b>Goal</b>: <br/>The main objective of this project is to construct Grätzel-type solar cells (DSSC) using natural pigments extracted from Ecuadorian plants and conduct a comparative study of their performance against standard cells based on synthetic pigments. This aims to establish the foundation for the successful adaptation of this alternative solar energy technology to local Ecuadorian conditions.<br/><br/><b>Research lines</b>: <br/>Study of weather and climate
