年卷期:Jin-Wook Lee received his B.S. degree in Electronic and Electrical Engineering from Sungkyunkwan University in 2011. Since 2011, he has been in a Ph.D. course in the Department of Energy Science at Sungkyunkwan University under the supervision of Prof. Nam-Gyu Park. His research has been focused on dye or quantum dot sensitized solar cells. He devotes currently his research to perovskite solar cells since the first report on solid state perovskite solar cells developed in 2012 by Prof. Nam-Gyu Park’s group.Hui-Seon Kim is a Ph.D. student in the Department of Energy Science at Sungkyunkwan University, Korea. She received her B.S. degree in Chemical Engineering from Sungkyunkwan University in 2011. She has been working on perovskite-based solid-state solar cells under the supervision of Prof. Nam-Gyu Park.Nam-Gyu Park is professor and SKKU-Fellow of School of Chemical Engineering at Sungkyunkwan University. He received the B.S, M.S., and Ph.D. degrees in Chemistry from Seoul National University in 1988, 1992, and 1995, respectively. He worked at ICMCB-CNRS, France, from 1996 to 1997 and at NREL, USA, from 1997 to 1999 as a postdoctoral researcher. He worked as Director of Solar Cell Research Center at Korea Institute of Science and Technology from 2005 to 2009 and as a principal scientist at Electronics and Telecommunications Research Institute from 2000 to 2005 before joining Sungkyunkwan University in 2009. He has been doing researches on high efficiency mesoscopic solar cells including photoelectrochemical dye-sensitized solar cell since 1997. He is one of pioneers in perovskite solar cell, where he developed for the first time the long-term durable perovskite solar cell in 2012.
