Our research group is interested in
using first row transition metal-based chromophores in order to lower the cost
and improve the efficiency of dye
sensitized solar cells (DSSCs). My
research involves the synthesis of Cu(I)
polypyridyl complexes that can then be used as sensitizers in DSSCs. While the reasons for choosing copper are
many, the abundancy of the metal plays a large role in the decision. Copper is >104 more abundant
than ruthenium, which is the metal that is most commonly used in DSSCs today. I am synthesizing
various Cu(I) polypyridyl complexes with the intent to carry out time-resolved
spectroscopic studies of these systems in 1) solution, 2) on an inert substrate
and 3) on TiO2 under operational conditions. These studies will allow me to determine the
relative rates of the various processes underpinning the overall efficiencies,
which will give insights into how to better design sensitizers for more
efficient DSSCs.
