Principal Scientist

Ingrid.Repins@nrel.gov | 303-384-7678

Dr. Repins is a principal scientist in the Reliability group at NREL. She has worked for more than 20 years in state-of-the-art device and module characterization, process research, and manufacture. She brings an in-depth understanding of materials science and device physics, with thin-film emphasis.

She is a member of the U.S. Technical Advisory Group for Photovoltaics, International Electric International Electrotechnical Commission Working Group for Photovoltaic Modules, and UL standards technical panel 1703.

Dr. Repins has been honored to work with outstanding teams to achieve a 2004 R&D 100 Award for “Lightweight Flexible Thin-Film CIGS PV Modules,” the world’s first 20.0%-efficient thin-film photovoltaic device, and the most highly cited 2008–2009 paper in the field of energy research.

Prior to joining NREL in 2008, Dr. Repins performed research and manufacturing support in the private sector.
