Dr. Peter Rupnowski, as a scientist in NREL’s Chemistry and Nanoscience Center, develops novel, high-speed, high-resolution, inline-compatible, nondestructive techniques for diagnostic and monitoring applications that focus on advanced energy materials used in low- and high-temperature fuel cells and Li-ion batteries. The techniques include hyper-spectral and thermal imaging for web-lines conveyed through roll-to-roll systems and active thermography for detection of electrolyte shorts and fatal cracks in ceramic parts.

In his previous assignment at Dow Corning and NREL, Peter worked on developing novel crystal growth techniques and led electro-optical and defect characterization activities for novel experimental silicon wafers and solar cells.

Dr. Rupnowski is co-recipient of a 2011 R&D 100 award and has co-authored two issued U.S. patents, 15 journal articles, and 44 conference publications.
