Prof. Angus H L YIP

Prof. Angus Yip joined the Department of Materials Science and Engineering (MSE) and the School of Energy and Environmental (SEE) at CityU as a Professor in 2021. He started his academic career as a Professor in the State Key Laboratory of Luminescent Materials and Devices (SKLLMD) and the School of Materials Science and Engineering at South China University of Technology (SCUT), Guangzhou in 2013. Since 2017, he has also been serving as the Director of the Innovation Center for Printed Organic Photovoltaics in the South China Institute of Collaborative Innovation, Dongguan, which aims to promote technology transfer and commercialization of new photovoltaic technologies. He received his BSc and MPhil degrees in Materials Science from the Chinese University of Hong Kong, and completed his PhD degree studies in MSE at the University of Washington, Seattle in 2008.

Prof. Yip’s research is in the general area of solution processed optoelectronic materials and devices for energy generation and energy saving. His research focuses on understanding the structure-property relationships, device physics and photophysics, and device optimization of 1) organic solar cells, 2) perovskite solar cells and 3) perovskite LEDs. His research group is highly interdisciplinary, with research scientists, post-docs and students from various backgrounds including Materials Science, Environmental Science, Physics, Chemistry and Engineering. He has published over 220 papers in top journals such as Nature (1), Science (1), Nat. Photonics (1), Nat. Commun. (5), Adv. Mater. (26), Adv. Energy Mater. (22), Adv. Funct. Mater. (11), Energy Environ. Sci. (6), J Am. Chem. Soc. (6), Joule (6), etc., with a total number of citations at ~25000 and an H-index of 80 (as of Jan 2021). He was named 7 times consecutively as a “Highly Cited Researcher” between 2014 and 2020. He received over 10 national and provincial grants, with a total funding scale of over 50 million RMB. In addition to fundamental research, he also dedicated a significant amount of effort to promote translational research, targeting for the commercialization of new generation of solar cell technology.

Prof. Yip’s research group is seeking highly motivated graduates and postdoc candidates who have solid backgrounds in Environmental Science, Materials Science, Chemistry, Physics, Engineering or other related fields. The research group provides opportunities to all members to explore their interests and be involved in both fundamental research and technology translation in the energy field. Interested applicants with strong motivation to perform cutting-edge research are highly encouraged to join Prof. Yip’s research group. Qualified candidates are welcome to submit their applications with CV and copies of transcripts via email to Prof. Yip.
