Perovskite & QD LED

Device engineering of perovskite LEDs and QD LEDs is crucial for achieving high-efficiency and high-stability devices. Particularly, improving the low stability of perovskite LEDs and QD LEDs (particularly,  blue LEDs) is an essential task that must be completed to realize self-emissive displays based on perovskites and quantum dots.

Our group pursues a deep understanding of structure-property relationships to solve the problems. In other words, we are interested in analyzing how material parameters (such composition, shell, dimension, and ligands) affects device efficiency and stability. Also, we engineer the charge injection/transport layers to achieve better charge balance and suppress the material degradation at the interfaces, which would lead to high efficiency and stability.
