Major Research Areas
Dye-Sensitized Solar Cells
We have been doing researches on design and synthesis of nano materials, sensitizers and redox electrolytes for high efficiency dye-sensitized solar cells. In addition, device architecture engineering is under development for high efficiency dye-sensitized solar cells. To increase light harvesting, selective positioning of dyes in nanocrystalline oxide semiconductors is developed. Solid state dye-sensitized solar cell is also under development, where redox electrolyte is replaced by solid hole conductor. Transient photocurrent and photovoltage spectroscopy is used to understand electron behaviour in dye-sensitized solar cell.
Organic Polymer Solar Cells
Using p-type and n-type organic materials, efficient organic polymer solar cell is fabricated. We have been focusing on design and preparation of interlayer to block efficiently electrons or holes. Nano inorganic oxides are candidates for this purpose. We are also conducting researches on quantum dot incorporated organic polymer solar cells.

Quantum Dot Solar Cells
Various quantum dot materials for conversion of light to electricity are designed and synthesized for use in high efficiency solar cells. Recently, we developed quantum dot solar cell with efficiency as high as 6.5% that is by far the world highest efficiency. To enhance further the efficiency, plasmonic and up and down conversion technologies are in parallel under development.
