electron transfer

Chemists in Arts & Sciences have re-engineered one of nature’s solar cells to drive electrons down an alternate path. This work advances the understanding of the earliest light-driven events of photosynthesis and is published in the Proceedings of the National Academy of Sciences.

Researchers at Washington University in St. Louis have shed light on a basic process that could improve future solar cells. Dewey Holten, Ph.D., professor of chemistry in Arts & Sciences and graduate student Hee-eun Song have directly measured the rate of hole transfer between identical porphyrin compounds in their ground states. These results are key to understanding the fundamental processes underlying charge separation in this sort of structure and have applications for improving the efficiency of solar cells.
