1st Runner-Up of the IEEE VIP Cup 2021

Supervised by Prof. Kenneth Lam, four BEng in EIE students, including Chang Chun-tzu, Chi Ziheng, Li Xinyue and Wang Shaozhi, teamed up with other students from the University of Technology Sydney won the First Runner-Up of the Video and Image Processing (VIP) Cup 2021 in the IEEE International Conference on Image Processing on 19 September 2021! The VIP Cup competition is sponsored by the IEEE Signal Processing Society. It encourages students to solve real-world problems by using video and image processing methods and techniques. The theme of the VIP Cup is "SLP Human Pose Estimation" this year. Contestants were asked to seek computer vision-based solutions for in-bed pose estimation under the covers. Our winning team presented a multi-level adaptation framework to progressively learn a well-generalized network for cross-domain human pose estimation in this competition. The experimental results demonstrate that the proposed framework can effectively generalize the learned knowledge from the uncovered source domain to the covered target domain for in-bed pose estimation.

World’s first ammonia-powered fuel-cell EV– Achievements by Professor Eric Cheng

Prof. Eric Cheng Ka-wai and his research team developed the world’s first ammonia-powered fuel-cell EV in just three months. The ammonia inside the fuel-cell system will be transformed into hydrogen to generate power. This new development is through the support from the University of Oxford and industry partners. The research team plans to develop an ammonia-powered fuel-cell mini-bus by October 2022 and hopes to collaborate with local mini-bus companies to promote zero-emission electric mini-buses.

Research Paper published in the Nature Photonics journal

A research team led by Prof. Gang Li published a paper “Stable and low-photovoltage-loss perovskite solar cells by multifunctional passivation” in the Nature Photonics journal in July 2021. Nature Photonics is a monthly journal dedicated to publish top-quality and peer-reviewed research in all areas of light generation, manipulation and detection. The journal covers research related to optoelectronics, laser science, imaging, communications and other aspects of photonics. It is regarded as a top-ranking journal in the field of photonics.  Metal halide perovskite solar cells have demonstrated a high power conversion efficiency (PCE), and further enhancement of the PCE requires a reduction of the bandgap-voltage offset (WOC) and the non-radiative recombination photovoltage loss (ΔVOC,nr). In this paper, the research team reported an effective approach for reducing the photovoltage loss through the simultaneous passivation of internal bulk defects and dimensionally graded two-dimensional perovskite interface defects. Through this dimensionally graded perovskite formation approach, an open-circuit voltage (VOC) of 1.24 V was obtained with a champion PCE of 21.54% in a 1.63 eV perovskite system (maximum VOC = 1.25 V, WOC = 0.38 V and ΔVOC,nr = 0.10 V); the team further decreased the WOC to 0.326 V in a 1.53 eV perovskite system with a VOC of 1.21 V and a PCE of 23.78% (certified 23.09%). This approach is equally effective in achieving a low WOC (ΔVOC,nr) in 1.56 eV and 1.73 eV perovskite solar cell systems, and further leads to the substantially improved operational stability of perovskite solar cells. The paper is available at https://www.nature.com/articles/s41566-021-00829-4.

2020 China’s Top Ten Optical Breakthroughs

Professor W Jin and his research team has worked on the “gas sensing research” which is honoured as “2020 China’s Top Ten Optical Breakthroughs” by China Laser Press.   In the applied research category, Professor Jin Wei, Chair Professor of Photonic Instrumentation, and his team developed a novel method of gas sensing called the Mode-phase-difference Photothermal Spectroscopy. The method was hailed as “a landmark technique in fibre-optic gas sensing” by a reviewer in Nature Communications, where the research results were published.  The innovation significantly outperforms state-of-the-art electrochemical and semiconductor gas sensors, and enables multi-component gas detection with a single sensing element. It paves the way for ultra-precision gas sensing for applications such as harmful gas detection in a space station and high voltage transformer condition monitoring.
