He is the manager of the High Efficiency Crystalline Photovoltaics Group at the National Renewable Energy Laboratory (NREL). His interests at NREL have been in the development of next-generation multi-junction high-efficiency solar cells for concentrator systems and the transfer of this technology to industry. One of his early focuses after joining the group was to adapt the GaInP/GaAs multi-junction cell technology for concentrator operation, developing the first monolithic two-terminal solar cell to have a verified efficiency with more than 30%. More recently, he has studied novel semiconductor materials for photovoltaics, such as GaInNAs for potential application in a 1-eV-bandgap device on conventional GaAs or Ge substrates, as well as developing concepts for junctions suitable for fabrication on Si. His current work centers on development of future generations of lattice-mismatched multi-junction cell structures for ultrahigh-efficiency operation under concentration. He received his bachelor’s in physics from Princeton University and his doctorate in applied physics from Stanford University. He joined NREL in 1990.
He came to the National Renewable Energy Laboratory (NREL) in late 2007 after spending 5 years with ZettaCore, Inc., a venture-backed company focused on integrating electrochemical charge storage into memory devices. He was the company's initial technical hire and successfully led several efforts that moved company technologies from academic laboratories into large-scale semiconductor fabrication facilities. While he maintains solid industry/business relationships, he also has a strong interest in fundamental issues regarding new materials for improved electrochemical devices, in particular electrochromic windows and lithium-ion batteries. At NREL, his research focuses on development of cost-effective, manufacturing friendly methods for the production of materials for both energy generation (photovoltaic) and efficiency (smart windows). He received his doctorate in chemistry with a specialization in electrochemistry from Mississippi State University in 2000 under the direction of Dr. David Wipf. His doctoral work focused on modification and characterization of carbon electrode surfaces using electrochemical microscopy techniques.
She is a materials engineer for the National Renewable Energy Laboratory in charge of determining new fluid formulations (molten salts, liquid metals, supercritical) for thermal applications. She is researching in corrosion mitigation to control degradation at high temperature under extreme conditions (mechanical, chemical, and thermal). She has become a material’s expert in solar thermal applications. She successfully managed complex, multimillion dollar projects, including coordinating multiple partners and professional scientists and engineers. Her understanding of the interaction of materials with the surrounding environment is key for selecting the appropriate materials used in thermal energy storage and heat transfer fluid systems. She has a patent, multiple publications in molten-salt utilization and characterization with applications as sensible heat fluid and phase-change materials, and other publications on corrosion evaluation of ceramics, alloys and surface treatments for high-temperature applications in harsh environments. She earned a bachelor’s and master’s in materials engineering from Simon Bolivar University and a doctorate from Colorado School of Mines in metallurgical and materials engineering. She also holds a research assistant professor appointment in the Metallurgical & Materials Engineering Department at the Colorado School of Mines. She has accumulated over 25 years of experience in materials science and engineering.
Robert Baldwin is a Principal Scientist in the National Bioenergy Center at the National Renewable Energy Laboratory in Golden, Colorado; he has worked at NREL since 2008. Dr. Baldwin holds the degrees Bachelor of Science and Master of Science in Chemical Engineering from Iowa State University (USA) and the PhD degree in Chemical Engineering from the Colorado School of Mines. Prior to joining NREL Bob spent 30 years as a faculty member at the Colorado School of Mines including 10 years as Head of the Chemical Engineering department and retired as Professor Emeritus in 2005. Bob is a member of the project team that founded the Petroleum Institute (PI) in Abu Dhabi, United Arab Emirates, and served as Program Director in Chemical Engineering
