Dr. Yang received his PhD degree in Microelectronics and Solid State Electronics from Wuhan University, China, in 2019. From 2019 to 2023, he worked as a Postdoctoral Research Fellow in the Department of Applied Physical Science at The University of North Carolina at Chapel Hill. Then, Dr. Yang joined The Hong Kong Polytechnic University as an Assistant Professor.

Dr. Yang has published over 50 peer-reviewed papers, including several high-impact papers in prestigious journals such as Nature, Nature Photonics, Nature Energy, and Joule, etc. As of August 2024, Dr. Yang’s H-index is 43 with over 8400 citations (https://scholar.google.com/citations?user=OnfZfzsAAAAJ&hl=zh-CN). His current work focuses on the optoelectronic characteristics of perovskite materials and their applications in optoelectronics, such as high throughput fabrication of perovskite modules and perovskite-based tandem devices as well as device physics.

Our specific research topics are listed below:

1. Perovskite-based tandem solar cells (Perovskite-Silicon, All-Perovskite, Perovskite-OPV)

2. High-throughput scalable manufacturing of perovskite modules and tandem modules

3. Device physics in optoelectronic devices and their characterizations

4. Photovoltaic applications: Floating solar desalination and Solar hydrogen generation

Openings

We are recruiting self-motivated Ph.D. students, Research Assistants, and Postdoctoral Research Fellows with a strong background in material science, microelectronics, physics, and chemistry for research in the field of optoelectronics, perovskite solar modules, and printable tandem photovoltaics. If you are interested, please send your CV (transcript) to guang.yg.yang@polyu.edu.hk.
