Speaker: Prof. Ching W. Tang
Doris Johns Cherry Professor,
Professor of Chemical Engineering,
University of Rochester, USA
Abstract: Organic solar cell has been studied since 1970s and in the last decade it has attracted a lot of scientific and technological interests due to the prospect of very low-cost solar cells on flexible substrate (employing printing or roll-to-roll processes). Prof. Ching W. Tang invented the heterojunction organic solar cell (so called, \"Tang\" Cell) in late 1970s in Eastman Kodak, USA. In this talk, he will review the history and recent development of the organic solar cells and provide his insights on the future development of organic solar cells.
Biography: Prof. Ching W. Tang was born in Hong Kong in 1947, and received his BS in chemistry from the University of British Columbia, Canada in 1970. He earned his Ph.D. in physical chemistry from Cornell University, USA in 1975. He joined Eastman Kodak in 1975 as a Research Scientist, was promoted to Senior Research Scientist in 1981, to Research Associate in 1990, and to Senior Research Associate in 1998. In 2003 he was named Distinguished Fellow of the Kodak Research Laboratories, Eastman Kodak Company. In 2006 he joined the University of Rochester as the Doris Johns Cherry Professor in the Department of Chemical Engineering. He also has joint appointments in the Department of Chemistry and the Department of Physics and Astronomy. He also became an Honorary Professor of Shanghai University and South China University of Technology, China (2002) and received an Honorary Doctorate Degree from Shanghai University, China (2010).
Prof. Ching W. Tang is the inventor of several ground-breaking electronic devices, including the organic light-emitting diode (OLED), and the heterojunction organic solar cell (\"Tang\" Cell). Efficient OLEDs were first developed by Prof. Tang at the research department of Eastman Kodak Company in the 1970s. He is widely recognized as one of the leaders in the organic electronics industry and in photovoltaics. He was elected to the National Academy of Engineering in 2006 for \"the invention of the organic light-emitting device and organic bilayer solar cell, the bases of modern organic electronics\". He also became a fellow of the American Physical Society (1998) and the Society for Information Display (2002). He received many awards such as Eastman Innovation Award from the Eastman Kodak Company (2000), Jan Rajchman Prize from the Society for Information Display (2001), Carothers Award from the American Chemical Society (2001), Humboldt Research Award from the Alexander von Humboldt Foundation, Germany (2005), Daniel E. Noble Award from the IEEE (2007), and Wolf Prize in Chemistry from the Wolf Foundation (2011).
