The Department of the Built Environment is delighted to share that the dissertation work by Hiew Jia Yee, Joey Tan titled “Performance Degradation of Photovoltaic Systems on Vegetated and Concrete Roofs in a Tropical Climate” was selected for an oral presentation at the 54th IEEE Photovoltaic Specialists Conference (IEEE PVSC) 2026 after a rigorous review by an international panel of expert reviewers. The panel of experts arrived at the decision based on the outstanding quality of the work. This research was conducted in collaboration with the KAJIMA Technical Research Institute Singapore (KaTRIS). The findings reveal that the co-location of PV and greenery reduces degradation across different PV technologies. Congratulations Joey!
