UNIST MSE
Optoelectronic Nanomaterials Engineering Lab (ONEL)
Research Objective
Our mission is to establish novel systems for solar-to-fuel energy conversion using organic semiconductors.
ONEL focuses on "solar fuel production," which involves converting solar energy into chemical energy at molecular level. One prominent example of solar fuel production is the reduction of water to produce hydrogen (green hydrogen) or the reduction of carbon dioxide to produce methanol, ethanol, and other compounds under illumination.
ONEL is developing various organic semiconductors (OSs) that can efficiently convert solar energy and aims to demonstrate practical systems for solar fuel production using these newly developed OSs. Through this integrated research, ONEL ultimately aims to achieve the circular economy.
