Author Bio:

Erming Feng got his BS and MS from Shijiazhuang Tiedao University and Shandong Normal University, respectively. Now he is a PhD student at Central South University under the supervision of Prof. Junliang Yang. His work focuses on organic solar cells.

Liming Ding got his PhD from University of Science and Technology of China (was a joint student at Changchun Institute of Applied Chemistry, CAS). He started his research on OSCs and PLEDs in Olle Ingan?s Lab in 1998. Later on, he worked at National Center for Polymer Research, Wright-Patterson Air Force Base and Argonne National Lab (USA). He joined Konarka as a Senior Scientist in 2008. In 2010, he joined National Center for Nanoscience and Technology as a full professor. His research focuses on innovative materials and devices. He is RSC Fellow, the nominator for Xplorer Prize, and the Associate Editor for Journal of Semiconductors.

Junliang Yang received his PhD in 2008 from CIAC, CAS. He then joined Tim S. Jones Group at the University of Warwick. In April 2011, he moved to Australia and joined Andrew B. Holmes Group at the University of Melbourne and CSIRO. In 2012, he was appointed as a professor in School of Physics and Electronics at Central South University. His research focuses on perovskite solar cells, organic solar cells, flexible and printed electronics.
