XianKai Chen

Research Scientists & Postdocs

XianKai Chen earned his Ph.D. d at Jilin University in 2015 and his major was theoretical chemistry. During Sep. 2012 ~ Mar. 2014, XianKai joined the Bredas group at Georgia Institute of Technology and mainly focused on the polaron models related to the electron-transfer problem. After XianKai obtained his Ph.D. degree, he performed the postdoc research in the Bredas group in King Abdullah University of Science and Technology and mainly focused on the non-radiative recombination loss in organic solar cells and molecular design of thermally activated delayed fluorescence emitters.

Research Interests

  1. Optical and electronic processes in organic and organic-inorganic hybrid materials
  2. Density functional theory (DFT) and time-dependent DFT
