| Outline of Final Research Achievements |
In this study, a series of ruthenium-complex sensitizers have been synthesized by introducing a functional group, which can serve as a sensitizer for the wavelength range below 500 nm, to the terpyridine ligand for the development of an efficient ruthenium-complex sensitizer showing a self-cosensitization effect. 2-hexylthienyl unit was found to be the most suitable and effective functional group, and the 4-position of the terpyridine derivative ligand was also found to be the most effective position to improve the cosensitization effect. Novel ruthenium sensitizer with a terpyridine derivative ligand having a 2-hexylthionyl unit at the 4-position (TUS-38) showed an effective cosensitization effect, and 11.9% conversion efficiency, which is much higher than that obtained in the photovoltaic devices based on a well-known highly efficient ruthenium sensitizer, was obtained in the photovoltaic devices based on TUS-38.
