How Nature harvests solar light

Towards physical-chemical analogs of the photosynthetic systems inspired by natural mechanisms of excitation energy transfer and charge separation.

The success of photosynthesis relies on two ultrafast processes: excitation energy transfer in the light-harvesting antenna followed by charge separation in the reaction center. Both processes occur with a quantum efficiency close to one, the natural system is highly adaptable, and self-protected. Crystal structure of a variety of light-harvesting complexes have become available over the last 15 years and many have been studied in great detail using ultrafast lasers and other advanced spectroscopic techniques.

In this talk I will illustrate which design lessons we have learned from nature that could inspire engineers to improve photosynthesis or in the construction of physical-chemical analogs.
