Abstract: Abstract Nowadays, more than the 80% of the world energy produced and consumed comes from non-renewable energy sources. These sources are usually concentrated in specific areas and their extraction and exploitation for many years has developed a critical situation of unsustainability and serious contamination problems. Therefore, the obtainment of energy from more accessible and cleaner sources, which also have the ability to regenerate themselves, is the key point for the maintenance of our standard of living and the economic growth of our current economy. Among all the studied renewable energies, solar energy is a hot topic. The optimization to collect, store and get electricity from this source is a much investigated issue, and thanks to that investigation the fabrication and commercialization of several devices which a significant efficiency has been already possible. However, in order to make the price of these devices able to compete with that from fossil fuels, the improvement of solar device systems and thereby the increase of their global efficiency is highly needed. Therefore, the investigation on this camp has to keep improving. The aim of this work is to make a little contribution to this investigation and consists in the synthesis of a nobel molecule that can improve the function of a perovskite solar cell, a solar device very new and promising, and consequently its global efficiency. This work includes basic fundamentals of these solar cells, to make possible to understand how they operate and how they are characterized, an experimental section, where a detailed of the synthesis of the new molecule and the devices fabrication is explained, and finally a description of the results obtained Abstract Nowadays, more than the 80% of the world energy produced and consumed comes from non-renewable energy sources.

Estas fuentes a menudo se encuentran en puntos localizados del planeta, y su extracción y explotación durante años ha provocado hoy en día un serio problema de sostenibilidad y varios problemas grabes de contaminación. Por consiguiente, la obtención de energía a partir de otras fuentes, más limpias, accesibles y renovables, es hoy en día un punto clave para el mantenimiento de nuestro nivel de vida y el crecimiento económico de nuestra economía. De entre todas las fuentes de energía renovables una de las más estudiadas es la solar. La optimización para poder recolectar, almacenar y aprovechar esta energía es un tema de investigación candente, y gracias a esto ya se han fabricado y comercializado dispositivos con una eficiencia significativa. Sin embargo, con el objetivo de seguir aumentando la eficiencia de estos dispositivos para que su precio de mercado pueda competir con el de las energías no renovables, es muy importante que esta investigación se siga desarrollando. En este trabajo se hace una pequeña aportación a esta investigación, ya que se basa en la síntesis de una nueva molécula que permita mejorar la función de una parte de una celda solar de perovskita, un tipo de dispositivos muy nuevos y prometedores, y en consecuencia aumente su eficiencia. El trabajo incluye un fundamento teórico básico y necesario para entender el funcionamiento de estas celdas solares y su caracterización, una parte experimental donde se describe la síntesis de la molécula objetivo y la fabricación de dispositivos, y finalmente una descripción de los resultados obtenidos.
