Joel Jean is a co-founder and CEO of Swift Solar, a US start-up developing high-efficiency, lightweight, and flexible perovskite photovoltaics. Joel previously served as the founding executive director of the Tata-MIT GridEdge Solar research program, focusing on scale-up of new solar photovoltaic technologies for India and other developing countries. As a researcher and NSF Fellow at MIT, he developed ultra-lightweight and flexible solar cells that were recognized by the 2017 Katerva Award, and he was named a Forbes 30 Under 30 Fellow in energy. He co-authored the MIT Future of Solar Energy Study and has worked extensively on emerging PV materials and devices, techno-economic analysis, and energy and climate policy. Joel holds a PhD and a SM in electrical engineering from MIT and a BS with distinction from Stanford University.  Patrick Richard Brown is a postdoctoral researcher at the MIT Energy Initiative. His research focuses on quantifying the near-term competitiveness of photovoltaics, wind, and energy storage across the US electricity system and on technical strategies for integrating high levels of renewable energy into electric power systems. He completed his PhD in physics at MIT, where his thesis research explored the use of colloidal nanocrystals as light-absorbing active materials in thin film solar cells, and his BS in physics and chemistry from the University of Notre Dame. He was a co-author of the MIT Future of Solar Energy study and received a graduate certificate in science, technology, and policy for work on the implications of technological advancement in solar and wind technologies for international climate policy.
