Research Direction Our research activities involve interdisciplinary science dealing mainly
with nanoscale semiconductor materials and photo-electrochemistry. We aim
to develop platform techniques of efficient light-electricity (fuel) conversion
from the sun, an inexhaustible, clean energy source. In particular, we
focus on the chemical synthesis of a wide range of nanomaterials including
organic-inorganic and inorganic compounds, paving a new approach to create
high-performance photovoltaic devices (dye-sensitized and perovskite solar
cells) and artificial photosynthesis systems (water-splitting photocatalysts).
One of the key materials we pay attention to is titanium dioxide and their
thin-films whose microstructures and physicochemical properties can be
precisely controlled in order to produce the nanomaterials-based ‘mesoscopic’devices
as mentioned above. Studies on versatile photoenergy conversions are currently
underway in our Lab.
