The Lab for Efficient and Enduring Energy systems (LE3) at the University of Michigan (Department of Chemical Engineering) conducts research at the intersection of nanofabrication, energy conversion, and transport of light and heat. Our efforts are primarily aimed at developing materials and devices that improve the reliability and accessibility of renewable energy and help decarbonize industry. Current research areas include (i) photovoltaic conversion of thermal radiation and thermophotovoltaic batteries for long-duration energy storage, (ii) transparent aerogel materials for solar process heat, power, and fuels, and (iii) understanding light-matter interactions in nanoscale photo-catalysts for sustainable chemical production. The team applies theoretical and computational tools to material design, implements advanced techniques for fabrication and characterization, and assesses device properties using custom-built experimental stations.
Our research has been supported by the US Department of Energy, DARPA, US National Science Foundation, General Motors, Michigan Economic Development Corporation, 3M Foundation, Antora Energy, UofM’s Graham Sustainability Institute and Center for Socially Engaged Design.
