Dr. Ajeet Rohatgi is a Regents’ Professor and the John H. Weitnauer Jr. Chair in the School of Electrical and Computer Engineering at Georgia Tech. He is also a Georgia Research Alliance Eminent Scholar, the founding director of the University Center of Excellence for Photovoltaic Research and Education at the Georgia Institute of Technology, and the founder of Suniva Inc.
Dr. Rohatgi has conducted research in the areas of optical and electrical properties of semiconductors, gettering and passivation of impurities and defects in Silicon, modeling, design, and fabrication of low-cost high-efficiency cells on mono, multi, and ribbon silicon. His company, Suniva Inc., pioneered the use of ion implantation technology for the mass production of high-efficiency silicon solar cells. Dr. Rohatgi has produced several world-record high-efficiency silicon solar cells using innovative cell designs and technologies. His group designed and built the world’s largest rooftop grid-connected PV system (342 kW) on the 1996 Olympic Natatorium. Dr. Rohatgi is currently working on next-generation carrier-selective tunnel oxide passivating contact technologies that can lead to greater than 27% efficiency low-cost silicon solar cells and more than 35% efficient silicon-perovskite tandem cells to drive the cost of PV electricity well below fossil fuels.
Dr. Rohatgi’s industry-relevant research led to the establishment of the nation’s first University Center of Excellence in PV at Georgia Tech in 1992, followed by the foundation of Suniva Inc. in 2007. Dr. Rohatgi is an IEEE Fellow. He has published over six hundred technical papers and holds 19 U.S. patents. He served as General Chair for the 28th IEEE Photovoltaic Specialists Conference in Alaska in 2000. He received the Westinghouse Engineering Achievement Award, the Georgia Tech distinguished Professor Award, the IEEE PVSC William Cherry Award, the NREL/DOE Rappaport Award, and the EPA Climate Protection Award. He also received the Excellence in Renewable Energy Award for Industry Leadership and the Georgia Tech Award for Outstanding Achievement in Research, Innovation, and Technology Commercialization. In 2010, he was named Champion of PV by Renewable Energy World magazine. In 2013, he became a Georgia Research Alliance Eminent Scholar and was inducted as a Fellow of the National Academy of Inventors in 2016.
