Biography

Fuzong Xu is a Postdoctoral Researcher in the KPV_LAB at KAUST. His research focuses on high-efficiency and stable multi-architecture perovskite–silicon tandem solar cells. He pioneered four-terminal perovskite–perovskite/silicon tandem devices, achieving world-record efficiencies, and was the first to report perovskite/perovskite/silicon triple-junction solar cells exceeding the efficiency of equivalent-area perovskite/perovskite tandems. His work has appeared in Joule and ACS Energy Letters. He aims to translate tandem technologies into scalable applications and to address the fundamental instabilities of perovskite materials.

Research Interests

My research interests lie in the development of high-efficiency, high-stability, and multi-architecture perovskite–silicon tandem solar cells. I am particularly focused on understanding and mitigating degradation pathways in perovskite materials and interfaces, with the goal of achieving scalable and commercially viable tandem devices. Future directions include translating record-breaking device architectures into industrial production and exploring fundamental mechanisms underpinning perovskite instability.
