Excited-state properties of Ruthenium-based black absorbing dyes

Within my PhD studies I am investigating the excited-state properties of a new family of Ruthenium polypyridine dyes. These dyes are capable of absorbing light over a wide range of the visible spectrum what makes them interesting for light-harvesting applications, e.g. as sensitizers in dye-sensitized solar cells.

Combining the results of experimental techniques as resonance Raman and ultra-fast transient absorption spectroscopy with results from TD-DFTTime-dependend density functional theory calculations, the photophysical properties of these systems are investigated.
