Professor in Department of Materials Science and Engineering at City University of Hong Kong
Research focuses on understanding photophysics and optimizing organic and hybrid perovskite devices
SRFS project — aims to develop a new generation of solar cells with higher efficiency, stability, and adaptability. Specifically, the project is creating all-perovskite triple-junction tandem solar cells, which can achieve power conversion efficiencies above 33%. The outcome will be solar devices that are not only highly efficient but also thin, light, and versatile. They can be integrated into building façades and windows, applied in aerospace and marine environments, and used as portable energy sources. This innovation will support Hong Kong’s 2050 carbon neutrality target and contribute globally to advancing renewable energy technologies.

赞词

本项目致力研发新一代高效全钙钛矿三结迭层太阳能电池，旨在实现光电转换效率超过33%，超越现有传统太阳能电池约27%的效率上限。此项突破将带来重大技术跃进，能在同等光照条件下产生更多清洁能源，提升成本效益，推动其长远发展。

钙钛矿材料具备轻质、吸光波段可调及低成本印刷加工等优势，因此特别适合构建高效迭层电池。然而，该技术仍面临几大关键挑战，包括部分材料组成稳定性不足、容易分解或氧化；迭层电池中的中间连接层需要同时具备优异的电荷复合与保护功能；以及可靠的封装技术对确保器件稳定性及实现柔性应用至关重要。研究团队将通过材料组分优化、界面钝化技术、新型沈积工艺开发及多物理场电池模拟，系统性提升电池稳定性。同步开发的高效中间连接层结构与抗老化封装方案，将促进实验室成果转化为具规模化的实用技术。最终实现高效、轻巧、多功能太阳能电池，不但有机会取代传统太阳能电池，更可广泛应用于建筑光伏一体化幕墙、航空航天器供电系统、海上光伏平台及便携电子设备。

此项突破不仅为香港2050碳中和目标提供关键技术支撑，更能为高密度城市提供分布式清洁能源解决方案，加速全球可持续转型。
