Principal Investigator

Assistant Prof. HOU Yi

Yi Hou is a Presidential Young Professor in the Department of Chemical and Biomolecular Engineering at the National University of Singapore (NUS). He was appointed the Head of the Perovskite-based Multijunction Solar Cell Group at the Solar Energy Research Institute of Singapore (SERIS) in September 2020. Yi obtained his Ph.D. degree (SAOT scholarship) in Materials Science and Engineering at the University of Erlangen-Nuremberg in Germany. His postdoctoral training in the Department of Electrical and Computer Engineering at the University of Toronto was mainly focused on photophysics and transport properties of the hybrid semiconductor in photovoltaics. He has several visiting scholar experiences at various universities overseas, such as the University of Oxford, UK; Swiss Federal Institute of Technology Lausanne (EPFL), Switzerland; Australia National University (ANU), Australia; and Stanford University, US.

Yi was recognized as one of the Innovators Under 35 (Asia Pacific) by MIT Tech Review due to his contributions to advancing perovskite-based tandem solar cell technology. In 2022, his achievement in setting a world record for the efficiency of a perovskite/organic tandem solar cell was documented in the “Solar cell efficiency tables (Version 60)”. Furthermore, in the same year, Clarivate Analytics honored him as a Highly Cited Researchers in the field of Cross-Field category. Moving forward to 2023, the Hou Group established yet another benchmark by achieving a world record efficiency for a single-junction perovskite solar cell (1 cm2), a feat acknowledged in the “Solar cell efficiency tables (Version 62)”.
