Dr Wing Chung Tsoi is a Lecturer. His research interests are mainly focus on solution-process photovoltaic/solar cells, including organic solar cells, and perovskite solar cells.
He is particularly 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 of the photovoltaic/solar cells.
His expertise is on developing/applying advanced (nano-) characterization methods to probe the structures/morphology 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 (AFM) as well as photovoltaic cells for indoor, power generation window and aerospace applications.
Dr Wing Chung Tsoi obtained his higher diploma in Applied Physics from The Hong Kong Polytechnic University. He then obtained BSc in Physics with Lasers and Photonics from The University of Hull. He obtained his PhD in Physics (Title of Thesis: Polymerisable Liquid Crystals for Organic Photovoltaics) 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 PV 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.
