Professor Hou Yi is a Presidential Young Professor in the Department of Chemical and Biomolecular Engineering at the National University of Singapore (NUS), Head of the Solar Energy Research Institute of Singapore (SERIS), and Editor of IEEE Journal of Photovoltaics. His research focuses on perovskite-based tandem photovoltaics, spanning device physics, materials engineering, and scalable manufacturing for next-generation energy applications. He has broken the world record for solar cell efficiency more than four times, published in leading journals including Science, Nature, and Nature Energy, and is recognized as a top 1 percent Clarivate Highly Cited Researcher worldwide. He is also an MIT Technology Review Innovators Under 35 (Asia Pacific) honouree, and major media outlets such as CNA and DW have featured his work. Professor Hou founded Singfilm Solar, a deep-tech spin-off that translates high-efficiency perovskite technologies into commercial products for aerospace and emerging space platforms. His work bridges fundamental innovation with industrial impact, advancing lightweight, high-efficiency perovskite tandem photovoltaics as a transformative alternative to GaAs-based space power systems, enabling future large-scale space activities and orbital data infrastructure.
