Yang Yang, the Carol and Lawrence E. Tannas, Jr., Chair in Engineering and a professor of materials science and engineering at the UCLA Henry Samueli School of Engineering and Applied Science, has been named a fellow of the American Physical Society.

Yang was cited by the society for “extraordinary contributions in organic and hybrid electronic materials, interfacial engineering, and novel device design that have led to highly efficient organic and hybrid solar cells, digital memory devices, vertical transistors and organic LEDs.”

Among the most highly cited researchers in the world in chemistry and materials science, according to Thomson Reuters, Yang joined the UCLA faculty in 1997. His work has led to greater understanding of polymer morphology and its influence on device performance; the invention of the inverted organic solar cells; and the invention of transparent organic photovoltaic devices. Along with fellow researchers, his lab has helped set several world records for power conversion efficiency in solar devices.

His recent work includes development of perovskite solar cells and photodetectors.

Yang, who received his Ph.D. from the University of Massachusetts Lowell, has more than 60 patents and has published more than 290 peer-reviewed papers.
