ABSTRACT

The frontier in solar energy conversion utilizing molecular and nanostructured building blocks now lies in learning how to integrate functional entities across multiple length scales to create optimal devices. To address this new frontier, I will discuss our recent efforts on elucidating multi-scale energy transfer, migration, and dissipation processes with simultaneous femtosecond temporal resolution and nanometer spatial resolution. We have combined/correlated ultrafast spectroscopy with high spatial resolution techniques such as optical microscopy and X-ray crystallography to achieve high-resolution spatial mapping of energy flow in nanostructures and solar energy harvesting systems.
