报告题目：Research highlights on organic and perovskite photovoltaics at Swansea University
In this talk, I will first give a brief introduction to the photovoltaic (PV) team at SPECIFIC, Swansea University. After that, advanced Raman techniques to characterize stability (and homogeneity) of organic and perovskite solar cells will be introduced. Then, fullerene degradations including effect of aggregation, and its contribution to degradation of organic solar cells will be explained, followed by dark bias effect and interlayer effect to perovskite PV degradation and efficiency. Finally, several emerging/new applications including organic PV for indoor, semi-transparent, aviation/space applications will be discussed. The aim of this talk is to update the latest development (2017-18) of the PV team (focus on my group), and foster collaborations.
Dr Wing Chung Tsoi is a senior research officer at the SPECIFIC photovoltaic (PV) team (chaired by Prof. James Durrant from Imperial College London) at Swansea University (UK). He is currently leading a group with particular focus on developing advanced characterization for organic and perovskite PV cells, and investigating emerging/new applications of organic and perovskite PV cells. Dr Tsoi’s current research includes developing new/advanced Raman-based techniques, understand and improve stability of organic and perovskite PV, optimize performance of organic and perovskite PV for indoor, power generation window and aviation applications. He has particularly expertise in new/advanced characterization techniques to understand structure-property-performance relationship of printable SCs, particularly world-leading in Raman spectroscopy for organic and perovskite PV. Dr Tsoi is also leading the area of organic PV for indoor applications (achieved highest power conversion efficiency). He has published 45 papers.
