Bryon Larson earned his doctorate in inorganic chemistry from Colorado State University under the supervision of Professors Steven H. Strauss and Garry Rumbles (NREL). His research focused on the synthesis, purification, and characterization of libraries of fullerene derivatives for fundamental and applied organic photovoltaics (PV) investigations. As a postdoctoral researcher with Nikos Kopidakis at NREL, he studied how certain molecular properties in PV-relevant compounds and polymers are expressed as bulk properties in a working device, by combining his training in chemistry, spectroscopy, and device physics.
He currently studies photoinduced charge carrier generation, transport, and decay dynamics in emergent thin-film and flexible PV materials, including organic semiconductors, metal-halide perovskites, and novel organometallic absorbers. In addition to spectroscopic characterization, his research includes solution-phase processing, solar cell fabrication, device physics, chemical analysis, X-ray crystallography, and material design to qualify and predict next-gen champion PV materials. His work also includes metrology solutions and scaling techniques for roll-to-roll manufacturing of photovoltaic modules. These efforts are supported through research grants from the Solar Energy Technology Office, Advanced Research Projects Agency–Energy, and Basic Energy Sciences within the U.S. Department of Energy as well as through industry partnerships.
