Joseph Berry is a senior scientist at the National Renewable Energy Laboratory working on halide perovskite solar cells. His PhD for work was on spin transport and physics in semiconductor heterostructures from Penn State University. His efforts at NREL emphasize relating basic interfacial properties to technologically relevant device level behaviors in traditional and novel semiconductor heterostructures including oxides, organics and most recently hybrid semiconducting materials. He leads the US Department of Energy (DOE) Solar Energy Technology Office’s SETO core technology program, “De-risking Halide Perovskite Solar Cells” at NREL. He is also a principle investigator on the NREL lead Department of Energy, Center for Hybrid Organic Inorganic Semiconductors for Energy (CHOISE) Energy Frontier Research Center, exploring basic aspect of hybrid materials.
