Organic Photovoltaics Based on Plasmonic Nanostructures
Zakya H Kafafi
Former Director of NSF Division of Materials Research and Optical Sciences Division at the Naval Research Laboratory, Adjunct Professor of Lehigh University
Recent progress in organic photovoltaics (OPVs) revealed the realization of 10% power conversion efficiency (PCE) putting them in direct competition with PVs based on amorphous silicon. Incorporation of plasmonic nanostructures in these thin-film devices for light trapping offers an attractive solution to realize ultrahigh-efficiency OPVs with PCE>>10%. In this talk, I will review recent progress on plasmonic-enhanced OPV devices using metallic nanoparticles, and one-, two- and three-dimensional (1-D, 2-D and 3-D) patterned periodic nanostructures.1,2 A discussion will be given on the benefits of using various plasmonic nanostructures for broad band, polarization insensitive and angular independent absorption enhancement, and their integration with one or two electrode(s) of an OPV device.

Dr. Kafafi received her B.Sc. (cum laude) from University of Houston with a major in chemistry and a minor in mathematics. Three years later she got her M.A. and Ph.D. in Chemistry from Rice University. She then crossed the Atlantic ocean and moved to Cairo where she pursued her academic career as an Assistant Professor for a few years before returning back to Houston on a sabbatical leave as a Visiting Professor at Rice University. She then decided to combine her chemical expertise and training with research in optics, and joined the Optical Sciences Division at the Naval Research Laboratory in Washington, DC where she established and led an interdisciplinary research team, and a section on Organic Optoelectronics. Her work has been motivated by newly emerging technologies based on organic electronics and photonics, spanning a wide spectrum of disciplines photonics and electronics including the chemistry and physics of organic and nanostructured materials, organic nonlinear optics, light-emitting materials and devices, and photovoltaics. More recently, she joined the National Science Foundation as the Director of the Division of Materials Research. She was the first woman to lead the largest and unarguably the most complex Division in the Mathematical and Physical Sciences Directorate. During her 3-year tenure, she managed a budget portfolio close to one billion dollar, and oversaw the funding of single and group investigators, interdisciplinary research teams and centers, instrumentation and major facilities. In 2011, she took a sabbatical leave and was a Visiting Scholar/Professor in the Departments of Electrical & Systems Engineering at UPenn and, Chemistry and Material Sciences & Engineering at Northwestern working with the groups of Professor Chérie Kagan and Tobin Marks, respectively. Dr. Kafafi has been an Adjunct Professor in the Department of Electrical and Computer Engineering at Lehigh University for the last five years. She is the Founding Editor-in-Chief of the Journal of Photonics for Energy. She serves on the Advisory Board of IEEE Photonics. She chairs the annual SPIE Symposium on Organic Photonics and Electronics, and the Conference on Organic Photovoltaics. She is a member of the American Chemical Society, the Materials Research Society, and Sigma Xi. She is a Fellow of the American Association for the Advancement of Science, the Optical Society of America, and the International Society for Optics and Photonics.
