| Outline of Final Research Achievements |
The purpose of this research is to develop new class of near-infrared absorbing materials, which are beneficial for efficient organic solar cells. In this study, new quinoid-type materials have been synthesized, and were found to be efficient near-infrared absorbing materials (absorption wavelength: ~890 nm). By applying these materials to donor layers of organic solar cells, a photocurrent conversion at near-infrared region has been achieved.
As a new class of the longer wavelength absorbing materials, donor-acceptor type boron complexes has been designed and synthesized. These boron complexes showed longer wavelength absorptions up to 1050 nm, which are essential for absorbing the sunlight.
