Senior Sustainability Scientist Zachary Holman’s research spanning the full spectrum of solar cell technologies has made him shine as a leader in the photovoltaics community. The assistant professor of electrical engineering in the Ira A. Fulton Schools of Engineering at Arizona State University recently was recognized with the 2019 IEEE Stuart R. Wenham Young Professional Award for significant contributions to photovoltaic energy conversion science and technology. This award is given annually by the photovoltaic section of the Institute of Electrical and Electronics Engineers. Holman's notable achievements include making new scientific developments and advancing performance to record efficiencies in solar cells based on silicon, cadmium telluride, perovskites and III-V materials. His most significant contributions have been to silicon-based tandem solar cells. These types of cells stack a complementary semiconductor material on top of silicon for efficient conversion of broad-spectrum light from the sun into electricity.
