Our research aims to achieve titanium dioxide layer 3D printing using print　technology, and a new titanium dioxide particle creation process through accurate control of titanium dioxide layers in highly efficient dye-sensitized solar cells. The novel titanium dioxide nanoparticle creation method and the static inkjet method are unique and innovative technologies.
Additionally, we are also tackling the creation of flexible photovoltaic cells and better design in photovoltaic cell development.

In recent years, the call has been rising for a new energy source independent of nuclear and fossil fuel sources. Our research aims to take water and sunlight, abundantly available worldwide, and separate the water into hydrogen and oxygen to use the hydrogen in a new energy producing system. The keys to our research lie in synthesis of photocatalyst by solution processes and in understanding the mechanism behind the photocatalytic water-splitting reaction. This has led us to develop a concrete objective plan that will lead to reactions of higher efficiency.

A current lead is a conductor that delivers a current from an electrical power source at room temperature to an ultra-low-temperature superconductor. Copper and copper alloys have been conventionally used, but when a current is applied the thermal conductance caused the heat load on the refrigeration system in the superconducting device. Our research and development has produced an ideal current lead that allows current to flow while making it difficult to transmit heat, using an extremely low thermal-conductivity Y-based superconducting tape made of oxidized ceramics that allows a high critical current at liquid nitrogen temperatures.
