Researcher's Profile

In Japan, it is greatly to be hoped that photovoltaic power generation systems will come into wide use as soon as possible. To achieve the aim, a drastic reduction in the power generation cost is absolutely essential issue. Molecular-based solar cells such as dye-sensitized solar cells and organic thin-film solar cells have received much attention as potential low-cost solar cells. Our objective is the efficiency enhancement of the molecular-based solar cells via the development of novel materials for near-infrared light absorption. We previously discovered several materials with panchromatic absorption by charge-transfer transitions, and we have successfully prepared a novel type of solar cells. Additionally, we are developing an energy-storable dye-sensitized solar cell.
