"Lessons from Nature on Solar Light Harvesting"

Abstract:

The sun is a dilute energy source and natural photosynthesis concentrates the solar excitation by means of large "antenna" systems connected to a reaction center which initiates the conversion of solar energy to chemical energy. The understanding of the design principles at work in natural photosynthetic light harvesting has advanced substantially in recent years. Progress has been made at the microscopic level, in particular revealing the existence of long-lived quantum coherence and, at the system level, in constructing a microscopically based model for the regulation of light harvesting in response to variations in solar flux. In this talk, I will summarize the recent progress and briefly suggest ideas for applications to synthetic systems.

"Multidimensional Ultrafast Spectroscopy: Materials, Molecules and Biosystems"

Abstract:

Over the past years, the technique of two‐dimensional spectroscopy has developed from the infrared spectral regime to the optical (visible) region of the spectrum. Most recently two‐dimensional visible---infrared spectroscopy has been implemented in my laboratory. In this talk, I will describe some of the applications and insights that these newly developed Spectroscopies have enabled on quantum---confined materials, molecular systems and biological systems, especially photosynthetic complexes.
