Dr. Ajeet Rohatgi received the B.S.T.(E.E.) degree from the Indian Institute of Technology in 1971, the M.S.(Materials Engineering) degree from the Virginia Polytechnic Institute and State University in 1973, and the Ph.D. (Metallurgy and Materials Science) degree from Lehigh University in 1977. He was a Fellow Engineer for the Westinghouse Research and Development Center, Pittsburgh. He worked on impurity effects on silicon solar cells, on semiconductor and device characterization, on impurity-induced recombination centers in semiconductors by deep level transient spectroscopy, in design and fabrication of photovoltaic and MOS devices, on physics and modeling of high efficiency solar cells, and high-energy particle radiation effects on power devices.
Professor Rohatgi's current research interests include modeling, design, fabrication and characterization of high efficiency silicon solar cells; materials for high performance photovoltaic and power devices; basic understanding of carrier lifetime limiting mechanisms in semiconductors; and materials for VLSI circuits.
Dr. Rohatgi is the director of the University Center of Excellence for Photovoltaic Research and Education (UCEP) at Georgia Tech. The UCEP is a Department of Energy center established to advance the science of photovoltaic devices and systems, to increase the availability of education in the area of photovoltaics, and to improve university-industry collaboration.
