Member of Chinese Academy of Sciences

Yongfang Ligot his M.Sand Ph.D. degree from East China University of Science and Technology in 1982 and from Fudan University in 1986 respectively. Then he entered Institute of Chemistry, Chinese Academy of Sciences (ICCAS) as a postdoctoral researcher in 1986 and became a staff of ICCAS in 1988 after finishing his postdoc. research. He was promoted to professor in 1993 in ICCAS. He ever did his visiting research in Institute for Molecular Sciences, Japan, from 1988.10. to 1991.4. and in University of California at Santa Barbara, USA, from 1997.6. to 1998.6. He was invited to be a professor in Soochow University in 2012 and was elected as a member of Chinese Academy of Sciences in 2013, a fellow of Royal Society of Chemistry (RSC) and a member of the executive council of Chinese Chemical Society (CCS) in2014.

Yongfang Li’s main research fields are photovoltaic materials and devices for polymer solar cells, the electrochemistry of conducting polymers and semiconductor nano-materials. He has published more than 500 research papers and given more than 90 plenary and invited lectures in international and domestic academic meetings and conferences. His papers have been cited by others for more than 17000 times with a h-factor of 67. He was named as “Young and Middle-aged Specialist with Outstanding Contributions in Natural Science” by Chinese government in 1998, .awarded theSecond-Grade National Award of China on Natural Sciencesin 1995 and theFirst-Grade Award of Beijing City on Science and Technologyin 2005. In 2012, he won “Macro2012 Lecture Award” from American Chemical Society. According to the announcement of Thomson Reuters, he is one of the 21 hottest scientific researchers in 2013 and one of the 147 highly cited researchers in the field of materials science, based on the data from 2002 to 2013.
