Dr. Brad MacLeod obtained his bachelor's degree in electrical engineering from the University of Alaska, Fairbanks, in 2005. His interest in renewable energy led him to study organic photovoltaics (OPVs) under advisement of Professor David S. Ginger in the Chemistry Department at the University of Washington in Seattle. Utilizing surface science techniques and custom-built bulk spectroscopies, his thesis focused on interface and electrode effects on the performance of organic semiconductor active layers in OPV devices. Upon obtaining a dual doctorate in chemistry and nanotechnology, he came to NREL to continue working in the area of contacts and interfaces in OPVs as a postdoctoral researcher under the supervision of Dr. Dana C. Olson. MacLeod's main contributions to the field have been in solution-processed ZnO-based electrodes used in OPVs for electron collection, where he utilized MgZnO alloys, self-assembling molecular surface modification, and alternative solution precursors to improve device efficiencies and stability under extended-duration testing conditions. He is interested in applying his knowledge of interfaces in OPVs to other energy devices and technologies, such as inorganic PV, batteries, solar fuels, etc.
