Garry Rumbles: NREL takes on challenges in the development of organic photovoltaics

As OPV efficiency improves, many mysteries still remain to be solved.
26 October 2012, SPIE Newsroom. DOI: 10.1117/2.3201210.06

Garry Rumbles works in the Solar Photochemistry program for the United States Department of Energy, at the National Renewable Energy Lab (NREL) in Golden, Colorado. His research focuses on the basic science of solar photoconversion and photoinduced electron transfer processes in polymer-based nanostructured interfaces, and increasing understanding of how charges are generated in organic polymers. Work in organic photovoltaics over the last decade has progressed to an efficiency of more than 10%,

Rumbles is a Research Fellow at NREL. He joined the lab in 2000 and is widely recognized for his research in photochemistry and photophysics of conjugated molecular systems, energy conversion in organic light emitting diodes and organic photovoltaic devices, and nanoscale morphology. He is a Professor Adjoint in the Department of Chemistry and Biochemistry at CU Boulder; and in 2009 he became a Fellow of the joint CU/NREL adventure: Renewable and Sustainable Energy Institute (RASEI). In 2004, he was made a Fellow of the Royal Society of Chemistry.

He presented a plenary talk at SPIE Optics + Photonics 2012 in San Diego:
