The Hong Kong Polytechnic University (PolyU) is dedicated to spearheading world-leading research and innovation for societal benefits. To recognise outstanding achievements with far-reaching impact locally and globally, PolyU has launched the inaugural “PolyU Top 10 Research & Innovation Stories of the Year” selection and voting campaign. From 20 remarkable research and technology translation stories announced in 2025, more than 7,700 members of the public and the PolyU community cast their votes. Combined with the scores of a professional judging panel, ten stories were selected as the final awardees. Among them, one is led by RISUD member:
| Principal Investigator | Research Topic | Research Focus |
|---|---|---|
| Prof. LI Gang Sir Sze-yuen Chung Professor in Renewable Energy, Chair Professor of Energy Conversion Technology of Department of Electrical and Electronic Engineering, Associate Director of Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE), Management Committee Member of Photonics Research Institute (PRI), Member of RI-IWEAR and Research Institute for Sustainable Urban Development (RISUD) Prof. YANG Guang Assistant Professor of Department of Electrical and Electronic Engineering, Member of RIAM, PRI and RISE |
Driving the commercialisation of energy-efficient solar cell technology towards a 40% efficiency milestone | Third-generation solar cell technology is advancing rapidly. The research team has reported a breakthrough in their review of perovskite/silicon tandem solar cells, addressing challenges in efficiency, stability and scalability. Their study aims to raise the energy conversion efficiency from the current maximum of about 34% to 40%. |
