Joseph Luther is a senior research fellow within the Materials, Chemical, and Computational Science directorate at NREL. He began his research career studying III-V light-emitting diodes and multijunction solar cells at North Carolina State University, and then moved to NREL during his graduate studies to study defects within various photovoltaic technologies. Under the direction of Arthur Nozik, while working on his doctorate through the Colorado School of Mines, he developed solar cells from colloidal nanocrystals, which exploit a phenomenon where multiple excitons are generated and harvested per incident photon. Luther then became a postdoctoral scholar in Paul Alivisatos’ group at the University of California, Berkeley, and Lawrence Berkeley National Laboratory. In 2009, he rejoined NREL as a senior research scientist.
Luther’s research interests focus on developing clean energy technologies through the frontiers of nanoscience and low-cost advanced processing. His research is funded by Basic Energy Sciences Energy Frontier Research Centers, the U.S. Department of Energy’s Solar Energy Technologies Office, the U.S. Department of Defense, strategic partnerships with industry, and NASA.
