An Arizona State University research team led by engineering professor Yong-Hang Zhang is striving to develop new solar cells that can achieve record levels of efficiency in converting sunlight into electrical energy.

Recent progress by the team is spotlighted in the current e-newsletter of the AVS (American Vacuum Society), an international organization of professionals working in the areas of materials technology, interfaces and processing.

Zhang’s research group in the Center for Photonics Innovation is building solar cell materials by layering monocrystalline cadmium telluride and magnesium cadmium telluride. The project is showing promise for revealing how the characteristics of these materials could produce much improved solar energy conversion efficiency – particularly for achieving conversion at a lower cost.

Zhang is on the faculty of the School of Electrical, Computer and Energy Engineering, one of ASU’s Ira A. Fulton Schools of Engineering, and is the Fulton Schools’ associate dean for research.

The report on his team’s research is under “Publication Highlights” with the title “Optical Study Helping Researchers Find Ways to Improve Solar Cell Efficiency” in the AVS e-newsletter.
