Jiangzhao Chen is currently a professor at College of Optoelectronic Engineering in Chongqing University. He is a member of the “100 People Plan” of Chongqing University. He received his B.S. and Ph.D. degrees in Applied Chemistry from Northeast Forestry University in July 2011 and in Optical Engineering from Huazhong University of Science and Technology in June 2016, respectively. From September 2016 to February 2019, he worked as a postdoctoral researcher in Prof. Nam-Gyu Park’s group at School of Chemical Engineering, Sungkyunkwan University. From March 2019 to November 2019, he worked as a postdoctoral researcher in Prof. Wallace C. H. Choy’s group at Department of Electrical and Electronic Engineering, the University of Hong Kong. He has long been engaged in the research of new thin film solar cells. Focusing on the key technical indicators of power conversion efficiency, stability, cost and other key scientific and technical issues faced by new thin film solar cells, the devices are systematically studied and explored from the aspects of material design and synthesis, device preparation and performance optimization, fine regulation of semiconductor physical properties, solvent engineering, additive molecular engineering, surface interface molecular engineering, mechanism analysis, etc. A series of technical bottlenecks faced by the commercial application of such solar cells have been broken through and a series of innovative and important research results have been achieved. Up to now, he has published 41 SCI academic papers in international well-known journals such as Science and Advanced Materials, which have been cited for more than 4000 times. h index is 19 and i10 index is 26. Among them, 35 SCI papers have been published as the first, co-first or corresponding author. 4 papers have been selected as ESI highly cited papers. 1 paper has been selected as ESI Hot Paper. The maximum number of citations in a single article exceeds 200. 9 papers have been cited more than 100 times. 19 papers have impact factors greater than 10, including Advanced Materials (4), Advanced Energy Materials (3), ACS Energy Letters (3), Nano Energy (1), Small Methods (2), Journal of Materials Chemistry A (2), Chemical Engineering Journal (3), and Green Chemistry (1). 5 invention patents have been applied. He presided over or participated in the National Natural Science Foundation of China, Chongqing Natural Science Foundation of China, Korea National Research Foundation, Fundamental Research Funds for Central Universities, Overseas Returnees Entrepreneurship and Innovation Support Plan, Chongqing University hundred Talents Plan research start-up fund and horizontal fund. He has made 10 invited reports in important academic conferences at home and abroad, such as China Materials Conference. As the chairman/co-chairman of the sub-conference, he successfully held the "National Conference on Energy Materials and Devices", "the third International Conference on Clean Energy Materials and Technology", "the third Western Conference on Materials" and other international and domestic academic conferences. He is a long-time reviewer of more than 10 international famous journals, mainly including Advanced Materials, Advanced Energy Materials, ACS Energy Letters, Advanced Functional Materials, Advanced Science, Chemical Engineering Journal, Journal of Energy Chemistry, etc. He currently serves on the editorial board of Science Frontiers and Chemistry and Chemical Research journals, guest editor of Materials Reports: Energy journal, standing member of expert Committee on Energy Materials and Devices, and project evaluation and consulting expert of Science and Technology Innovation Alliance of Chengdu and Chongqing Twin Cities Economic Circle.
