Dean Levi

Dean Levi received his Ph.D. in physics from the University of Illinois at Urbana-Champaign in 1990. He joined the Solar Energy Research Institute (now the National Renewable Energy Laboratory) as a post-doctoral research associate applying ultrafast laser spectroscopy to study hot carrier relaxation in semiconductor quantum wells. Throughout the 1990s he utilized time-resolved photoluminescence to study carrier dynamics and material properties of various semiconductors for second- and third-generation photovoltaics. In 2000 he turned his attention to the use of in situ real-time spectroscopic ellipsometry to the analysis of thin film deposition for photovoltaics. He is currently a line manager and senior technical staff member in the National Center for Photovoltaics at the National Renewable Energy Laboratory.
