Dr. Charlie Gay, Director

CharlieGay-web.jpgDr. Charlie Gay is the Solar Energy Technologies Office Director for the Office of Energy Efficiency and Renewable Energy (EERE) of the U.S. Department of Energy (DOE). In this position he is leading the SunShot Initiative, a team that is dedicated to research, manufacturing and market solutions to make solar energy cost competitive with other forms of energy by the end of the decade.

Dr. Gay is an internationally recognized pioneer in photovoltaics. After starting his career in 1975 designing solar power system components for communications satellites at Spectrolab, he later joined ARCO Solar, where he established the research and development program and led the commercialization of crystalline silicon and thin film technologies.

In 1990, he became president and chief operating officer of Siemens Solar Industries, and from 1994 to 1997, he served as director of DOE’s National Renewable Energy Laboratory. In 1997, he was named president and chief executive officer of ASE Americas, and from 2001 to 2005 served as founding chairman of the technical advisory board at SunPower Corporation.  He joined Applied Materials in 2006 as corporate vice president and general manager of the Solar Business Group. He served as president of Applied Solar and chairman of the Applied Solar Council from 2009-2013. As president, Dr. Gay was responsible for positioning Applied Materials and its solar efforts with important stakeholders in the energy industry, technical community and governments around the world.

He earned a Ph.D. from the University of California, Riverside and was elected a member of the U.S. National Academy of Engineering in 2013. He established the Greenstar Foundation in 1997 to demonstrate an economically sustainable model that delivers solar power and internet access for health, education and microenterprise projects to developing world villages.

Dr. Jones-Albertus has spent her career advancing solar cell materials and devices, from research and development to manufacturing. Previously, Dr. Jones-Albertus was the characterization and design manager at Solar Junction, where she led work contributing to the development of the company's breakthrough dilute nitride solar cells, their two-time world record triple junction solar cells, and then the successful transfer of that technology to a high-volume manufacturing toolset. She has 35 technical publications and 8 patents.

Dr. Jones-Albertus graduated magna cum laude from Princeton University with a B.S. in electrical engineering, and also holds a M.S. and Ph.D. in materials science and engineering from the University of California, Berkeley.

Dr. Paul Basore,  Chief Engineer

Paul Basore 2013 hires.JPGDr. Paul Basore’s thirty years in photovoltaics have spanned university, government and industrial positions across three continents. Dr. Basore is probably best known as the principal developer of PC1D and other software tools for device characterization and cost modeling that have found widespread use within the photovoltaics community.

Since receiving his PhD in electrical engineering from MIT for a thesis in the field of electromechanical energy storage for PV systems, he has managed the establishment of five PV R&D facilities. The first of these, at Sandia National Labs, fabricated the world’s first 15% multicrystalline-silicon module: a record that was not eclipsed until 15 years later. His next facility was a thin-film start-up in Australia that led to the establishment of a factory in Germany, where Paul served as the founding CTO. After moving to the San Francisco Bay Area in 2007, he established R&D labs for two of the world’s leading PV manufacturers: the Renewable Energy Corporation of Norway and Hanwha Q Cells of Korea. He was subsequently a Center Director at NREL in Golden, Colorado before joining the SunShot team. 

Caroline McCgregor, Acting Soft Costs Program Manager

Caroline McGregor is a senior policy analyst at the U.S. Department of Energy, where she is currently on detail from International Affairs to EERE’s SunShot program, leading the soft costs team. Prior to this, she led two initiatives for the Office of International Climate and Clean Energy, within the framework of the Clean Energy Ministerial, which is a forum of energy ministers from 24 major economy governments: the C3E Women in Clean Energy Initiative and the Global Lighting and Energy Access Partnership (Global LEAP). Prior to government service, she worked as a journalist in Russia for The Moscow Times. She received her BA from Wellesley College and an MPA from Columbia University’s School of International and Public Affairs.

Dr. Avi Shultz, Acting Concentrating Solar Power Program Manager

avi-headshot-cropped.jpgDr. Avi Shultz is the acting program manager for SunShot's Concentrating Solar Power (CSP) team, which supports research, development, and demonstration of solar thermal components and systems that can enable wide-spread deployment of low-cost CSP with thermal energy storage. Dr. Shultz has been with SunShot since 2013, where he started as a policy fellow and was hired as a federal technology manager, supporting the CSP subprogram on a wide variety of topics, including thermochemical energy storage, CSP systems and cost analysis, and non-electricity applications of solar thermal process heat. 

Prior to joining SunShot, Dr. Shultz was a Rubicon Post-Doctoral Fellow at the University of Amsterdam, where his research focused on developing supramolecular approaches to catalysts for artificial photosynthesis. Dr. Shultz holds a B.A. from Columbia University and a Ph.D. in chemistry from Northwestern University, performing his thesis research on the synthesis of catalytically active porous materials.

Dr. Lenny Tinker, Acting Photovoltaics Program Manager

Lenny_Head_Shot_resize.pngDr. Lenny Tinker has been at the U.S. Department of Energy Solar Energy Technologies Office (SETO) since September 2011 and started as an AAAS Science and Technology Policy Fellow on the Photovoltaics team working on Incubator Round 6.
