Abstract
The interest in using organic semiconductor thin films in electronic and optoelectronic applications has grown rapidly due to many technological advantages intrinsic to these unconventional semiconductors, such as low material cost, ease of processing, and compatibility with flexible substrates. Many organic-based devices, including organic light-emitting devices (OLEDs), photovoltaic (PV) cells, photodetectors, thin-film transistors, and memories, have been demonstrated over the last two decades, with OLEDs now available in commercial display products.
This talk is focused on the use of organic semiconductors to achieve high efficiency and low cost conversion between optical and electrical energies, examples of which include OLEDs as display or lighting devices and organic PV cells for the direct conversion of solar energy to electricity. After introducing the basic properties of organic semiconductors, I will present our recent work on high efficiency organic PV cells and deep-blue OLEDs. Key challenges for this field will also be identified.
Bio:
Prof. Jiangeng Xue obtained his Ph.D. in Electrical Engineering from Princeton University in Jan. 2005, working in the field of organic electronics with Prof. Stephen R. Forrest. He received a Solar Energy Innovation Award from Princeton University for part of his thesis work on high efficiency organic photovoltaic cells. After briefly working as a Research Scientist at Global Photonic Energy Corporation, he joined the Department of Materials Science and Engineering at the University of Florida in Gainesville, FL, as an Assistant Professor in Aug. 2005. He is a recipient of a Faculty Early Career Development (CAREER) Award from the National Science Foundation in 2007. His research interests are broadly on the physics and applications of organic and hybrid organic-inorganic electronic materials including nanostructures and energy materials. His work is currently funded by NSF, U.S. Department of Energy, DARPA, as well as industry.
