About

Professor Wing Chung Tsoi's research interests are mainly focus on third generation photovoltaic/solar cells, including organic photovoltaic cells, perovskite photovoltaic cells, and quantum dots photovoltaic cells. He is particularly interested in characterization and development of the third generation photovoltaic materials for emerging applications. Professor Tsoi had made pioneering and critical contributions to the application of third generation photovoltaic materials for indoor, aerospace and power biomedical electronic implants applications. His contributions were recognized by the nomination for the 2024 Eni Award by the Eni committee (Italy). Besides, he also interested in non-traditional photovoltaic materials/devices for emerging applications.

Furthermore, Prof. Tsoi also interested in understanding the structure-property-performance relationship of the photovoltaic/solar cells, in order to understand the fundamentals and to improve the performance, particularly the stability and efficiency of the photovoltaic/solar cells. His expertise is on developing/applying advanced (nano-) characterization methods to probe the structures/morphology and functionality of the photovoltaic thin films, and correlate it to the properties and performances. His particularly expertise is on advanced Raman spectroscopy and functional atomic force microscopy.

Professor Wing Chung Tsoi obtained his higher diploma in Applied Physics from The Hong Kong Polytechnic University. He then obtained BSc in Physics from The University of Hull. He obtained his PhD in Physics under supervision of Prof. Mary O'Neill at The University of Hull in 2006. During his PhD, he discovered novel light absorbing, charge transporting liquid crystals can be used as photovoltaic materials and to fine tune its nano-morphology to significantly improve the efficiency of the PV. He then took a postdoctoral position under Prof. David Lidzey at The University of Sheffield, working on organic semiconducting materials for novel ultrafast optical switching. During the period, he discovered that an interesting and special phase, so called "beta-phase" can be formed with fluorene oligomers. In 2009-2014, he was a research associate/fellow at Imperial College London and National Physical Laboratory worked on advanced characterization of organic photovoltaic devices.
