Author Bio:

Hengyang Xiang received his MS in Materials Science and Engineering from Soochow University in 2016 and PhD degree in Materials Physics and Chemistry from Sorbonne University in 2019. He is currently a lecturer at Nanjing University of Science and Technology. His research focuses on light-emitting diodes and photodetectors based on perovskites.

Chuantian Zuo received his PhD degree in 2018 from National Center for Nanoscience and Technology (CAS) under the supervision of Professor Liming Ding. Then he did postdoctoral research in CSIRO, Australia. Currently, he is an assistant professor in Liming Ding Group. His research focuses on innovative fabrication techniques for perovskite solar cells.

Haibo Zeng obtained his PhD in Materials Physics from Institute of Solid State Physics (CAS) in 2006. Following visiting scholar at University of Karlsruhe (with Prof. Claus Klingshirn and Prof. Heinz Kalt) and then postdoctoral work at National Institute for Materials Science (with Prof. Yoshio Bando and Prof. Dmitri Golberg), he joined the faculty at Nanjing University of Science and Technology in 2011 and initiated Institute of Optoelectronics & Nanomaterials in 2013. His research focuses on the exploratory design of semiconducting nanocrystals and 2D crystals, with an emphasis on optoelectronic applications.

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 Inganäs 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 functional materials and devices. He is RSC Fellow, the nominator for Xplorer Prize, and the Associate Editors for Science Bulletin and Journal of Semiconductors.
