HOME Introduction


I pursue the innovation of photovoltaic materials and devices technologies to achieve carbon neutrality and make the Earth sustainable.

Since I joined the Korea Institute of Energy Research in 2003, a government-funded institute specializing in energy technology, I have studied photovoltaic technologies consisting of solar cells, modules, and systems. I have developed the world’s best flexible thin-film solar cells and transferred these technologies to domestic industries through conducting various projects and research. I also founded several research-based spin-off companies.

Currently, I am a professor in the KENTECH Institute for Energy Materials and Devices at the Korea Institute of Energy Technology (KENTECH) in South Korea. I foresee developing high-efficiency flexible tandem solar cells, and establishing lab-ventures on next-generation solar cells and PV systems for the distributed renewable energy system.
