Outline of Final Research Achievements |
To improve the vertical carrier mobilities of organic semiconductor films, which are the key for higher performances of organic light-emitting diodes and organic solar cells, a promising molecular orientation control method was developed and relationship between film structure and electrical properties was elucidated. Reduced graphene oxide was first employed for molecular orientation control, resulting in controlling molecular orientation of organic semiconductor films such as oligo thiophenes. They achieved very high carrier mobilities in the vertical direction. Also, these orientation-controlled films were applied to organic solar cells and their performances were improved.
