About Inventor

Ching W. Tang, widely considered the father of organic electronics, built the first organic solarcell and the fi rst organic light-emitting diode (OLED) in the 1980s. The enabling innovation for both devices was made possible by an organic heterojunction—a bilayer structure of an electron donor and an electron acceptor. This structure can be used to fabricate exceptionally effi cient OLEDs and organic solar cells. Tang’s insights unleashed a torrent of activity in the fi eld and eventually sparked an industry. His seminal articles on organic photovoltaics and OLEDs were published in Applied Physics Letters 48 (1986) p. 183 and 51 (1987) p. 913, respectively. Now a professor at the University of Rochester, Tang discussed with MRS Bulletin his days at Kodak.

Tang's Life and Career

Tang attended secondary school at King's College and Yuen Long Public Secondary School in Hong Kong. Later Tang graduated with a BS in chemistry from the University of British Columbia, British Columbia, Canada in 1970. He subsequently earned his PhD in physical chemistry from Cornell University, NY, 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.

Tang is the inventor of several groundbreaking electronic devices, including the organic light-emitting diode (OLED),and the hetero-junction organic photovoltaic cell (OPV).Efficient OLEDs of small molecules were first developed by Tang at the research department of Eastman Kodak Company in the 1970s. Tang is widely recognized as one of the leaders in the organic electronic industry and in photovoltaics.Tang 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".

In addition to his pioneer research on the OLED and OPV, Tang made a number of critical innovations resulting in the commercialization of a new flat-panel display technology. These innovations include "the development of robust transport and luminescent materials, improved device architectures, novel color pixilation methods, and fabrication processes for the manufacture of passive-matrix OLED displays; and the adaptation of active-matrix backplane technology for high-definition OLED displays".

On 15 February 2011, Tang was awarded the Wolf Prize in Chemistry. He shared the prize with Professor Stuart A. Rice of the University of Chicago, and Professor Krzysztof Matyjaszewski of Carnegie Mellon University. The official citation for the three professors from the Wolf Foundation reads: "For deep creative contributions to the chemical sciences in the field of synthesis, properties and an understanding of organic materials; for exploring the nature of organic solids and their energy profiles, structure and dynamics and for creating new ways to make organic materials, ranging from polymers, to organic-based devices that capture energy from the sun, and light our way in the dark; and for groundbreaking conceptual and experimental advances that have helped to create the research field of organic materials."
