Obadiah Reid earned a PhD in Physical Chemistry from the University of Washington in 2010. While at UW, he worked under the guidance of Prof. David Ginger studying the optoelectronic properties of nanostructured organic photovoltaic composites. He contributed to the development and application of photoconductive atomic force microscopy (pcAFM), a unique tool for mapping local photocurrent collection in solar cells with nanoscale resolution. He also developed numerical models to describe conductive and photoconductive AFM experiments, resulting in quantitative local measurements of charge carrier mobility made using conductive AFM, and a method for measuring the local vertical composition in organic photovoltaic composites using pcAFM. His research interests include charge generation, transport, and recombination processes in organic semiconductors; development of new analytical tools and methods; and the convergent application of experimental and theoretical approaches.
