Professor Hyunho Lee (Electronic Engineering) and his research team developed high-efficiency top-emitting quantum dot light-emitting diodes using only solution processing

- Development of high-efficiency anode-hole injection layer through interface engineering

- Maximization of luminous efficiency and improvement of color purity through resonance condition optimization

The research team of Professor Hyunho Lee (Electronic Engineering) at Kwangwoon University, in collaboration with the research team of Professor Hyunkoo Lee at Sookmyung Women's University, succeeded in producing environmentally friendly top-emitting quantum dot light-emitting diodes using only solution processing by inserting a polyethyleneimine interface layer.

The research was supported by the National Research Foundation of Korea and the Institute of Information & communications Technology Planning & Evaluation. The research results were published in the renowned journal 'Advanced Electronic Materials' (IF: 6.2) by Wiley.
