Peter Rupnowski develops novel in-line, nondestructive techniques for quality control and monitoring of advanced materials used in the low- and high-temperature fuel cells and Li-ion batteries. The methods investigated include hyper-spectral, high-resolution optical and thermal imaging for webs conveyed through roll-to-roll system, and active thermography for detection of electrolyte shorts and fatal cracks in ceramic parts.

In his previous assignment at Dow Corning and NREL, Rupnowski worked on the development of novel crystal growth techniques, and on electro-optical, fracture, and defect characterization for silicon wafers and solar cells. Rupnowski is a corecipient of an R&D 100 Award in 2011 and has authored a few U.S. patents,and numerous journal and conference publications, which were cited more than 550 times.
