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.
