Research Interests

Photovoltaics are expected as future clean energy sources and have the potential to serve a variety of applications. High efficiency multi-junction solar cells, conventionally utilized for space satellites, are studied aiming at terrestrial usage as well. One of our research themes focuses on the technique called as "epitaxial lift-off", a method to separate the solar cell device layer from its semiconductor substrate, as one of the key technologies to make expensive high efficiency solar cells cheaper. Our research interests include dilute nitride (III-V-N) semiconductors and quantum dot systems for photovoltaics and optoelectronic devices.
