Sigurd Wagner

My work involves the development of devices, processes, and materials for large-area electronics and solar cells. I am helping to lay the groundwork for the direct printing of electronic circuits. Printed electronic products like digital wallpaper, smart structures, and electronic barcodes will open the new industry of macroelectronics. 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 coinvented 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 Center for Photonics and Optoelectronic Materials reflects my interest in displays and solar cells. 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 was born and raised in Austria, have held visiting appointments at the Electrotechnical Laboratory, Tsukuba, Japan, 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, and am a fellow of the American Physical Society. I am the author of over 300 publications and coinventor in eleven U.S. patents.
