Quantum dot solar cells

Nano-sized semiconducting crystals (quantum dots) demonstrate unique features distinguished from their bulk counterparts such as quantum confinement effect and multi-exciton generation. Owing to the unique optoelectronic properties, quantum dot solar cells are considered as a next-generation device for solar energy harvesting that can possibly surpass the Schockley-Queisser limit. Our group tailor crystal structure and synthetic processes of the semiconducting quantum dots to demonstrate high-performance quantum dot solar cells.

Flexible/stretchable devices

The electronic devices are becoming ubiqutous in our life in the form of wearable and IoT (internet of things) devices for various applications such as diagnosis, therapy, entertainment, and information devices. Accordingly, a demand for light and flexible/stretchable devices are gradually increasing as a platform to achieve these applications. We interested in development of stretchable/flexible electronic materials and devices. These devices can be potentially integrated into wearable devices or e-skin for health care and robots with artificial intelligence (AI).

Tandem devices & Neuromorphic devices

We are also interested in emerging devices such as tandem devices and neuromorphic devices.
