Head and shoulders shot of Garrett Nilsen

Garrett Nilsen is the acting director for the U.S. Department of Energy Solar Energy Technologies Office, which advances research and development in solar energy technologies. Garrett has managed over a hundred research and development projects covering all technology spaces in the office. Multiple technologies from projects he managed are now actively used in the solar energy industry. In addition, Garrett has been involved in the development of prize programming, technical assistance efforts, and data analysis. Garrett specializes in the transition of research and knowledge to stakeholders across the solar energy industry.

Garrett joined the office in 2012, and has had led both the Manufacturing and Competitiveness team and the Balance of Systems Soft Costs team. He has worked with businesses of all sizes focusing on the development of innovative products and manufacturing technologies to help drive down costs and increase the deployment of solar energy. He has helped innovators in the solar energy space de-risk their research, products and processes to make them attractive to private investment along with helping them access the resources and develop the skills needed to make an impact on solar energy.

He has also worked on the other side of government contracting—from 2007-2009, he worked as an optical engineer for Technologies Solutions and Invention, a small business in Connecticut that was an awardee on government contracts to develop optics-based devices for various government customers.

Garrett has a B.S. in physics from Union College in New York and an M.S. in solar energy engineering from Hogskolan Dalarna (Dalarna University) in Sweden.

Dr. Paul Basore, Chief Scientist

Paul Basore SETO Portrait

Dr. Paul Basore is the chief scientist for the U.S. Department of Energy’s (DOE) Solar Energy Technologies Office (SETO). In this role, he provides guidance for strategic planning, program evaluation, techno-economic analysis, and scientific methodology. His four decades in solar power technology span industrial, academic, and government positions on three continents, including positions within DOE's National Laboratory solar programs at Sandia National Laboratories and the National Renewable Energy Laboratory and a previous role in SETO. Since assuming his current position in January 2021, he has been stationed in San Diego, California.

After receiving a Ph.D. in electrical engineering from Massachusetts Institute of Technology in energy storage technology to support solar power, Paul focused his attention on crystalline-silicon photovoltaics (PV). He led the development of PC1D, a program for personal computers to simulate the internal operation of silicon solar cells, which became the most widely-cited PV cell simulation program for more than 25 years. He then developed a method for extracting the internal electrical and optical properties of solar cells from their response to monochromatic light of varying wavelength. He subsequently led the scale-up of a thin-film crystalline-silicon PV technology from laboratory to commercial production and led the advanced research and development labs in two tier-one silicon module manufacturing companies. Nine U.S.-issued patents list him as the inventor. Paul has published papers in forward-looking techno-economic analysis and the future evolution of PV manufacturing. He chaired the IEEE Photovoltaic Specialists Conference in 1997 and received the outstanding paper award for silicon PV in 2003.
