Outline of Final Research Achievements

We studied the improvement of dye sensitizers containing organoboron complexes as chromophores. In this study, we focused on the light absorption and the charge transfer properties of dyes, and synthesized new organoboron dyes for dye-sensitized solar cells. Study of these photovoltaic characteristics suggested that the process of light absorption → excitation → electron injection in solar cells occurred smoothly. Thus, we successfully observed maximum external quantum efficiencies of 80% range. As the result, the conversion efficiency reached 5.2%, which was a good value among the power conversion efficiencies of organoboron dyes. These results are significant information in the development of organoboron dyes for dye-sensitized solar cells.
