In an Age of Obesity, Why Do Some Remain Thin?
The tale of two rats, in short, is the story of why some rats (and people) do not gain weight while others do. It suggests a “chicken and egg” question of which comes first – obesity or inactivity.read more
Kent State College of Arts and Sciences Holds Symposium on Advances in Organic PhotovoltaicsPosted March 24, 2014
Researchers will present findings on new flexible solar-powered materials
Kent State University will host its third annual Symposium on Advances in Organic Photovoltaics (OPVs) on April 16 from 9 a.m. to 6 p.m. in the Moulton Hall Ballroom on the Kent Campus. The symposium is free and open to the public and serves as a platform for discussions about OPV research, opportunities and development. A poster session and reception will follow the presentations starting at 4:30 p.m.
OPVs are specialized, carbon-based materials used in solar cells and unlike typical solar cells that are silicon or thin-film-based. They are flexible and have the potential to be produced at much lower costs than conventional solar cells using processes such as jet-printing, spray painting and roll-to-roll manufacturing.
The symposium’s morning keynote speaker is Zhenan Bao, Ph.D., professor of chemical engineering at Stanford University. Prior to joining Stanford in 2004, she was a Distinguished Member of Technical Staff in Bell Labs, Lucent Technologies from 1995-2004.
Bao’s presentation, "Molecular Design and Solution Shearing to Manipulate Molecular Packing, Morphology and Electronic Properties of Organic Semiconductors," will shed light on polymer and small molecule semiconductor materials as alternatives to inorganic semiconductors in applications where low-cost, flexible or transparent substrates, and large area format is required.
The afternoon keynote speakers are Peter Green and Lars Müller-Meskamp. Green is the Vincent T. and Gloria M. Gorguze Professor of Engineering and chair of the Materials Science and Engineering department at the University of Michigan, Ann Arbor. He also is the director of the Center for Solar and Thermal Energy Conversion (CSTEC), a Department of Energy-sponsored Energy Frontier Research Center (EFRC). His presentation, “Morphological Design, Transport Processes and Device Performance of Organic Solar Cells,” will discuss research on carrier transport processes (carrier mobilities recombination, charge generation) in specific morphologies for the poly(3-hexylthiophene):phenyl-C61 butyric acid methyl ester (P3HT:PCBM) system, engineered to possess different morphologies, and the effect on device performance parameters.
Müller-Meskamp heads a research group for alternative transparent electrodes and encapsulation for organic optoelectronic devices at Institut für Angewandte Photophysik, Technische Universität Dresden (IAPP). Before joining the IAPP, he worked at Qimonda Dresden in the development of flash memory technology. His presentation, "Alternative Transparent Electrode Technologies and Encapsulation for Organic Photovoltaics," will discuss a number of materials and technologies for transparent electrodes.
Kent State’s initiative on OPVs started in 2009 when a group of its faculty members from the Departments of Physics, Chemistry, Chemical Physics, and the College of Technology (now the College of Applied Engineering, Sustainability and Technology) developed a proposal under the Coordinated Research Hiring Initiative to create three new faculty positions.
The symposium features invited presentations from professionals in the region, including Paul Lane, Ph.D., of the Naval Research Laboratory; Quan Li, Ph.D., senior research fellow, Liquid Crystal Institute at Kent State; Björn Lüssem, Ph.D., assistant professor of physics, Kent State; Kenneth D. Singer, Ph.D., of Case Western Reserve University; and Wei You, Ph.D., of University of North Carolina at Chapel Hill.
