时间： 2015年5月28日 (星期四) 上午9:30-10:30The research of organometal trihalide perovskite solar cells continues to boom with device power conversion efficiency approaching that of single crystal solar cells. One critical step in understanding why hybrid perovskite solar cells work so well is to determine the carrier diffusion length in them. I will present the advance in discovering the scaling of carrier diffusion length, which varies from nanometer to centimeter scales, in the hybrid perovskites with respect to material morphology and fabrication methods. I will also introduce our progress of using low temperature solution processes to achieve high device efficiency to 19% in planar heterojunction architecture devicesProf. Jinsong Huang received his PhD degree from the UCLA in 2007. After working in Agiltron Inc., he joined the University of Nebraska-Lincoln (UNL) in 2009 as an assistant professor, and was promoted to associate professor in 2014. His current research interests include solution processed electronic materials for applications in sensing, energy and consumer electronics. He is the coauthors of over 70 publications, including Science, Nature Materials, Nature Nanotechnology, etc. He was elected as William E. Brooks Engineering Leadership Fellow in 2014. He serves as an associate editor for Scientific Reports. He has received several prestigious awards such as NSF CAREER Award (2013).联 系 人 朱 瑞 (62750853)
