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.

Next-Generation Tandem Perovskite Solar Cells: High-Efficiency, Flexible, and Scalable Solutions for Diverse Applications

讚詞

本項目致力研發新一代高效全鈣鈦礦三結疊層太陽能電池，旨在實現光電轉換效率超過33%，超越現有傳統太陽能電池約27%的效率上限。此項突破將帶來重大技術躍進，能在同等光照條件下產生更多清潔能源，提升成本效益，推動其長遠發展。

鈣鈦礦材料具備輕質、吸光波段可調及低成本印刷加工等優勢，因此特別適合構建高效疊層電池。然而，該技術仍面臨幾大關鍵挑戰，包括部分材料組成穩定性不足、容易分解或氧化；迭層電池中的中間連接層需要同時具備優異的電荷複合與保護功能；以及可靠的封裝技術對確保器件穩定性及實現柔性應用至關重要。研究團隊將通過材料組分優化、界面鈍化技術、新型沉積工藝開發及多物理場電池模擬，系統性提升電池穩定性。同步開發的高效中間連接層結構與抗老化封裝方案，將促進實驗室成果轉化為具規模化的實用技術。最終實現高效、輕巧、多功能太陽能電池，不但有機會取代傳統太陽能電池，更可廣泛應用於建築光伏一體化幕牆、航空航天器供電系統、海上光伏平臺及便攜電子設備。

此項突破不僅為香港2050碳中和目標提供關鍵技術支撐，更能為高密度城市提供分布式清潔能源解決方案，加速全球可持續轉型。
