Sigurd Wagner

Professor of Electrical Engineering
Ph.D. 1968, University of Vienna

I am working on devices, processes, and materials for large-area electronics, which is also called macroelectronics or giant electronics. Macroelectronics includes flat panel displays, rigid, flexible or foldable, electronics shaped to cover irregular surfaces, electronic skin and e-textiles. My active device technology is based on thin-film silicon. My research interests stem from a career that began at the Bell Telephone Laboratories in 1970, where I worked first within the 1 Kb RAM project, and then on new device applications for ternary chalcopyrite-type compound semiconductors and other novel electronic materials. In the course of this research I co-invented several new solar cells, of which the CuInSe2/CdS cell is in industrial production. As branch chief, I established between 1978 and 1980 the photovoltaic laboratory of the newly founded Solar Energy Research Institute at Golden, Colorado. In 1980 I joined Princeton University as professor of electrical engineering.

My appointment in Princeton's Institute for the Science and Technology of Materials reflects my interest in electronic materials. I also hold an appointment in the Program in Plasma Science and Technology because of my work in plasma-enhanced deposition of silicon films. My participation in the Princeton Environmental Institute arises from an interest in environmental aspects of electrical engineering. I also am an associate of the Liechtenstein Institute on Self-Determination. I was born and raised in Austria, have held visiting appointments at the Electrotechnical Laboratory, Tsukuba, Japan, the University of Linz, Austria, and was a senior fellow of the Humboldt Foundation at the University of Constance, Germany. I have been active in the IEEE, the Materials Research Society, and the Electrochemical Society, am a fellow of the American Physical Society, of the Institute of Electrical and Electronic Engineers, and a Corresponding Member of the Austrian Academy of Sciences. I am the author of over 450 publications and coinventor in thirteen U.S. patents.
