Team Led by Prof. Jen Received Green Tech Fund (HK$5.03 Million)

The project led by Professor Alex Jen Kwan-yue, Director of Hong Kong Institute for Clean Energy and Lee Shau Kee Chair Professor of Materials Science, received funding worth HK$5.03 million. His team will develop highly efficient printable perovskite solar cells (PSCs) to help Hong Kong become a leading city in developing technologies for solar energy. 

Named Chair Professorship Scheme

Prof. Jen was awarded the first session of the named chair professorship scheme. The first-ever inauguration ceremony for Named Chair Professorships at City University of Hong Kong (CityU) on 11 October honored distinguished scholars for their outstanding achievements and paid tribute to our generous donors. 



Prof. Jen won the 2021 Outstanding Research Award (senior faculty). The Outstanding Research Award recognizes the outstanding researchers for their eminent performance and work. 


Prof. Jen's research work was published on Nature Nanotech. This achievement is noted as a major technological breakthrough and innovatively proposed the “dilution effect” concept as the fundamental working mechanism of multiple-component organic solar cells (MC-OSC).
