Resumen:
This thesis is based on a type of photovoltaic devices; the dye sensitized solar cells (DSCs). In the last two decades, the study of these devices has been increased and currently results with over 13% efficiency have been published. The first chapter discusses the various components of this kind of device, its function and its components. It is also explained how these cells work and all the reactions and physical phenomena that take place. The second chapter explains how to prepare these devices and how are characterized. And the third, fourth, fifth and sixth chapters are based on diverse articles published and the difference between them is the kind of dye. In chapter 3, the dyes used are porphyrins, chapter 4 is based on phthalocyanines, chapter 5 is centred on organic dyes that have a structure called donor-acceptor with a π-bridge type in between and chapter 6 studies two ruthenium complexes.
