We are an ultrafast spectroscopy group specializing in the development and application of two-dimensional infrared (2D IR) spectroscopy to study chemical processes in functional organic electronic materials. Ultrafast infrared spectroscopy is combined with electrochemical techniques to elucidate the structure and dynamics of charged defects and their involvement in electron transfer, charge carrier diffusion, and bimolecular charge recombination in emerging photovoltaic materials. Ultrafast and microsecond time scale infrared methods are also utilized to study the influence of the dielectric properties of materials on bimolecular charge recombination and charge transport processes.
