Abstract

The continues use of fossil fuels leads to their inevitable depletion and their use results in products harmful to the environment. Therefore, the development of new technologies for energy production is a major issue for society. As an alternative energy source, solar radiation can be used as it is abundant and does not produce waste during its converted to other forms of energy. This conversion is done through solar cells, but the commercial available ones cost of manufacture is quite high. Third-generation solar cells are manufactured with mild chemical processes, reducing not only their costs but also the time manufacturing. The most promising class of third-generation cells are perovskite solar cells. The main disadvantage of these cells is their short life span. The present thesis deals with the synthesis and characterization of porphyrin derivatives in order to introduce them into perovskite solar cells at two different layers of the cell. Two of the porphyrin derivatives were studied as intermediate layers between the electron transport layer (ETL) and the perovskite, improving the performance and lifetime of the device. In addition, porphyrins with different metal centers were synthesized and characterized, which are to be coated as an interlayer at the ETL / perovskite interface. Finally, the third family of compounds described in this thesis consists of porphyrins with known electron donor groups, which will be deposited as a hole transfer layer in these solar devices.
