Improvement of Dye-Sensitized Solar Cells

Dye-Senitized Solar Cells(DSSCs) have simple structure but the electrical efficiency is less than that of silicon type cells. We improve the efficiency by dispersing fluorescent pigment powder in electrolyte solution and changing the wavelength of light to be adsorbed to the dye.

Improvement and Application of Reversible Gel

Nanosilica suspended in polymer aqueous solution gelates by shaking and regains the fluidity by stopping. We study this "reversible gel" about improvement of long-term stability and application.









The repulsive force of the road surface with the reversible gel bag at gel state under the wood chip pavement became higher than sol state. This road adsorbs shocks when we walk slowly and becomes harder when we run fast.

Electro-Hydro Dynamics（EHD）

When high voltage is applied to insulating liquid directly, high-speed jet flow appears. We studied this "Electro-hydro Dynamics (EHD)" under various conditions - fluids and electrode marerials.

Molphology Control by Heterogeneous Electric Field

When high voltage is applied to some particle suspensions, particle aligns between two electrolytes and forms column structure (Electrorheology, ER effect). We try to control the microstructure (molphology) of materials by heterogeneous electric field using various types of electrodes.
