Shenghan Wu received his BS degree from Henan University in 2023. Currently, he is a PhD candidate under the supervision of Prof. Dewei Zhao in College of Materials Science and Engineering, Sichuan University. His research focuses on wide-bandgap perovskite solar cells and perovskite/silicon tandem solar cells.
Dewei Zhao received his PhD degree from Nanyang Technological University, Singapore, in 2011. Since 2012, he has worked as a postdoc at University of Michigan and University of Florida and as a research assistant professor in Prof. Yanfa Yan's group at the University of Toledo. Currently, he is a professor at College of Materials Science and Engineering, Sichuan University. His research focuses on organic/inorganic hybrid optoelectronic devices, such as thin-film solar cells, light-emitting diodes, and photodetectors.
