Ultra-high efficiency multijunction solar cells using monolithically integrated II/VI and III/V materials

Prof. Yong-Hang Zhang
Department of Electrical Engineering

Director
Center for Nanophotonics

Arizona State University, Tempe

Thursday, October 23, 2008 - 4:00 P.M., NSH 184

 

 I will first introduce the newly established Center for Nanophotonics at the Arizona Institute of Nanoelectronics and some of the research highlights of my group. Then, I will discuss our newly proposed idea to use lattice-matched II/VI (MgCdZn)(SeTe) and III/V (AlGaIn)(AsSb) materials grown on GaSb substrates for ultra-high efficiency solar cell applications. Detailed modeling and preliminary experimental results have shown great potential of this materials system.

 

 

Professor Zhang received his BS and MS in China and did his PhD research work at the Max Planck Institute for Solid States and received his degree in Physics from the University of Stuttgart in 1991. He then worked as an Assistant Research Engineer at UCSB before he joined Hughes Research Labs in 1993. In 1996, he became an Associate Professor in the Department of Electrical Engineering at ASU. He was promoted to full professor in 2000. He is the founding director of the Center for Nanophotonics at the newly established Arizona Institute for Nanoelectronics. His areas of research interest include multijunction solar cells, semiconductor lasers and photodetectors, optical properties of semiconductor quantum structures, and their applications.
