Matsui Laboratory

About Us

We develop future organic electronics materials and devices using computer physical chemistry and experiments.
Because organic semiconductor devices are thin, lightweight, flexible, and ecofriendly in manufacturing,
they are expected to find applications in healthcare sensors, robot skins, smart agriculture, displays, and photovoltaics.
Our recent focus is materials informatics to develop promising organic materials using material databases,
physical chemistry simulations, and machine learning.
