Nam-Gyu Park is a Lifetime Distinguished University Professor in the School of Chemical Engineering and Director of the SKKU Institute of Energy Science and Technology (SIEST) at Sungkyunkwan University (SKKU). He received his B.S. degree in chemical education in 1988 and his M.S. and Ph.D. degrees in chemistry from Seoul National University in 1992 and 1995, respectively. He conducted postdoctoral research at ICMCB-CNRS, France (1996–1997), and at the National Renewable Energy Laboratory (NREL), USA (1997–1999). Prior to joining SKKU as a full professor in 2009, he served as a senior researcher at the Electronics and Telecommunications Research Institute (ETRI) from 2000 to 2005 and as director of the Solar Cell Research Center at the Korea Institute of Science and Technology (KIST) from 2005 to 2009. He is an elected Fellow of the Korean Academy of Science and Technology (KAST). His research centers on photovoltaic materials and devices, with nearly three decades of contributions to solar energy science. In 2012, he reported the first long-term stable solid-state perovskite solar cell, lauching the modern era of perovskite photovoltaics. His subsequent work has advanced the understanding of perovskite materials, device physics, crystallization control, and interface engineering, supporting the rapid development of high-efficiency perovskite solar cells. In recognition of his scientific impact, Prof. Park was named a Citation Laureate (top 0.01% scientist) in 2017 and has been included in Clarivate’s Highly Cited Researchers list (top 1%) from 2017 to 2025. His honors include the Samsung Ho-Am Prize (2018), the Rank Prize (2022, UK), the National Academy of Engineering of Korea Grand Award (2024), Korea’s Top Scientist and Technologist Award (2024), the Eni Award (2024, Italy), the Humboldt Research Award (2025, Germany), and the NIMS Award (2025, Japan). He also serves the scientific community as Senior Editor of ACS Energy Letters.
