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
