報(bào)告人簡介：

Alex Jen is currently serving as the Provost and Chair Professor of the City University of Hong Kong. Before his current post, he was the Boeing-Johnson Chair Professor and Chair of the Department of Materials Science & Engineering at the University of Washington. He was also the Chief Scientist for the Clean Energy Institute endowed by the Washington State Governor. His research interest is focused on utilizing molecular, polymeric and biomacromolecular self-assembly to create ordered arrangement of organic and inorganic functional materials for photonics, opto-electronics, nanomedicine, and nanotechnology. He has co-authored more than 820 publications, given over 550 invited lectures. His work is well cited with more than 48,000 citations and a h-index of 112. He is also a co-inventor of more than 50 patents and invention disclosures.

For his pioneering contributions in organic photonics and electronics, he was elected as Fellow for AAAS, MRS, ACS, PMSE, OSA, and SPIE. He has also been appointed as the 1000 Talent Chair Professor by Zhejiang University, the Changjiang Chair Professor by the Chinese Ministry of Education, as the World Class University Professor by the Korean National Research Foundation, and as the Distinguished Chair Professor by the National Taiwan University. He has been recently appointed as the Honorary Professor by the National Chiao-Tung University and elected as an Academician by the Washington State Academy of Sciences.

報(bào)告摘要：

Advances in controlled synthesis, processing, and tuning of the properties of non-fullerene acceptors and perovskites have enabled significantly enhanced performance of organic and organic- perovskite hybrid solar cells. The performance of hybrid perovskite solar cells is strongly dependent on their efficiency in harvesting light, charge transport, and charge collection at the organic bulk-heterojunction and perovskite interfaces. In this talk, an integrated approach of combining material design, interface, and device engineering to significantly improve the performance and stability of organic and hybrid perovskite photovoltaic cells (PCE of >21%) will be discussed. At the end, several new device architectures and optical engineering strategies to make tandem cells and semitransparent solar cells will be discussed to explore the full promise of these solar cells.
