| Outline of Final Research Achievements |
In this research, new types of solar cells have been studied to improve their performance. The solar cells have sensitized material for light absorption, which are call "sensitized solar cell (SSC)." It is necessary to utilize the photo-excited carriers to improve the performance, but there are several loss processes for the photo-excited carriers, which is called as "recombination processes." We focus on these processes for reducing these loss processes. We have developed time-resolved microscopic techniques to study the recombination processes in terms of the time and structure relevant to the processes. We clarified the reason why the cobalt redox species have not worked for the SSCs with ruthenium dyes, and the reason why the TEMPO redox did not show a good efficiency for SSCs. Furthermore, we have developed a new phase microscope in which the refractive index image can be obtained for the photoexcited carriers in photo-devices.
