Organic photovoltaic (OPV) devices and related thin-film photovoltaic technologies such as organic light-emitting diodes (OLEDs) are typically based on photoactive molecular semiconductors, semiconducting polymers, and/or hybrids of these materials with semiconducting oxide and low work function metal contacts. These dissimilar materials must form chemically and physically robust interfaces for efficient charge harvesting or charge injection. Dramatic improvements in efficiency and lifetime of these devices will not be possible without optimization of interfacial charge transfer events that is founded on a molecular-level understanding of the physical and chemical interactions that control these interfaces. This seminar will consider specific examples of fundamental optical and electron spectroscopic studies designed to illuminate the chemical and physical details of critical interfaces in these devices with a special focus on interfaces formed between low work functional metal contacts and organic semiconductors.

Jeanne E. Pemberton is a Regents’ Professor and the John and Helen Schaefer Professor of Chemistry at the University of Arizona. Her research interests lie in the area broadly defined as interfacial chemistry where she works on the development and use of a variety of molecular spectroscopic probes to understand the chemistry within interfaces that are important in optoelectronic devices, self-assembling systems, and biosurfactants and bio-inspired surfactants. She completed her undergraduate education at the University of Delaware where she received a B.S. with Distinction in Chemistry and a B.A. in Biology in 1977. She received her Ph.D. at the University of North Carolina at Chapel Hill in 1981 and started as an Assistant Professor of Chemistry at the University of Arizona later that year, rising through the ranks to the level of Professor. She was appointed as the John and Helen Schaefer Professor of Chemistry in 2001 and as a Regents’ Professor in 2005. Her work has been recognized with multiple awards including the American Chemical Society Award in Analytical Chemistry in 2004, and she has received multiple Awards for Special Creativity from the National Science Foundation for her work. She is a Fellow of the American Chemical Society and of the American Association for the Advancement Science. She is an Associate Editor of the American Chemical Society journal Analytical Chemistry and co-Editor of Annual Review of Analytical Chemistry. She has served on the National Research Council Board on Chemical Sciences and Technology and the NSF Directorate for Mathematical and Physical Sciences Advisory Committee, which she chaired in 2004.
