Outline of Final Research Achievements

We studied titanium dioxide electrodes of dye-sensitized solar cells which is expected as a new solar cell. By using original titanium complexes as starting materials, needle-like titanium dioxide was synthesized and an electrode was fabricated using this sample, showed higher energy conversion efficiency than random shaped titanium dioxide. In addition, various polymorphs of titanium dioxide were prepared, and the properties as electrodes were investigated. Compared with the anatase type which is most frequently used, the brookite type was found to have a low current value but a high voltage can be taken out.
