Jung Hwan Kim

Jung Hwan Kim is a Professor in the Department of Energy Resources and Geosystems Engineering at Sejong University. He holds a Ph.D. in Chemical Physics from the University of Maryland at College Park (2001), M.S. (1992) and B.S. (1990) in Physics from Yonsei University. His academic career includes positions as Assistant Research Scientist (2004-2010) and Research Associate (2001-2004) at the University of Maryland/Laboratory for Physical Sciences before joining Sejong University in 2010.

• Education:
  • Ph.D., University of Maryland at College Park (Chemical Physics, 2001)
  • M.S., Yonsei University (Physics, 1992)
  • B.S., Yonsei University (Physics, 1990)

His research focuses on compound semiconductor photovoltaic cells, energy-efficient photonic devices, and high-speed semiconductor devices. Recent work spans battery recycling (closed-loop cathode resynthesis), electrochemical energy systems (CO2 reduction, fuel cells), and advanced photovoltaic device engineering. Articles show trends in semiconductor heterostructures, electrochemical modeling, and sustainable energy materials.

Scientific contributions include:

• Developing heterojunction photovoltaic cells with quantum well structures in GaP
• 60 GHz optical gain cutoff frequency and 20dB up-conversion gain in phototransistors
• Monolithic distributed traveling wave photodetectors integrated with polymer waveguides
• Leading Li-ion battery recycling technologies
• Developing prototype fuel cell systems

He has received multiple Research Excellence Awards (2011-2024) and the Sejong Merit Award (2015). His Electrochemical Energy Conversion & Storage Lab at Sejong University advances energy system technologies, with significant contributions to UN Sustainable Development Goals 7 (Affordable and Clean Energy) and 13 (Climate Action).
