The first solar cells based on the p-n junction technology appeared in the late 1950s, but they were very expensive to produce. In 1991, based on work from Goodenough, Memming, Kirsch-De Mesmaeker and Gerischer, amongst other, M. Grätzel and B. O'Regan developed a new type of photovoltaic cell: Dye-Sensitized Solar Cell (DSSC). In 1999, T. J. Meyer designed the first Dye-Sensitized PhotoElectrochemical Cells (DSPEC). This was a significant scientific breakthrough where, on the one hand, interfacial electron transfer was used to generate a photocurrent and, on the other hand, the oxidized photosensitizer was regenerated by a catalyst that could, in turn, perform a chemical transformation. A decade later, T. E. Mallouk reported a water splitting DSPEC using an IrOx catalyst and the field has continued to evolve with several innovations in catalysis and chemical transformations. In this master thesis project, the synthesis of various heteroleptic Ruthenium(II) terpyridine complexes is reported for their use as photosensitizers in the development of photoanodes in DSPECs. The complexes were anchored via their phosphonic acid function on various metal oxide surfaces (TiO2, SnO2, nanoITO) prepared and characterized in the laboratory. Finally, the influence of the bridge (phenyl, tolyl or xylyl) between the metal center and the semiconductor was studied using time-resolved UV-Visible spectroscopy.photochemistryinterfacesmetal oxideselectron transferDSPECRuthenium complexeswater splittingmechanism investigationsolartext::thesis::master thesisthesis:46226
