Bryon Larson

Researcher III-Chemistry

Bryon.Larson@nrel.gov | 303-384-6449

Dr. Larson received his Ph.D. 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.

At NREL, he studies charge-carrier transport, generation, and decay dynamics in thin-film flexible (PV) materials, including organic semiconductors, perovskites, and novel inorganic absorbers. In addition to spectroscopic characterization, his research includes solution-phase processing, device physics, chemical analysis, and material design to qualify and predict next-gen champion PV materials. His work is supported through the SuNLaMP initiative under DOE’s Solar Energy Technology Office, as well as through industry partnerships.
