Outline of Final Research Achievements |
In this study, we carried out the following fundamental researches on organic devices. Cyclic- and star-shaped polymers with short-wavelength absorptions were successfully synthesized. Power conversion efficiencies (PCEs) of organic solar cells (OSCs) using cyclic-shaped polymers were higher than those using conventional linear polymers. On the basis of solid-state NMR analysis, short-wavelength absorption type OSCs with high PCEs were successfully fabricated using a new polymer, especially without using halogenated solvents. These results will contribute greatly for the developments of environmentally-friendly tandem-type OSCs. In addition, we carried out device fabrications by a slot-die coater, whose PCEs were almost the same or slightly higher than those by the conventional spin-coating method. We also carried out studies on device degradation analysis, multiscale charge transport calculations, and organic light-emitting diodes. The progress of this study is beyond the expected.
