| Outline of Final Research Achievements |
In this project, nanocarbon materials such as graphene and single-walled carbon nanotube (SWNT) were utilized as electron-acceptors (A), which were covalently linked with electron-donating photoactive molecules (D) such as porphyrin and pyrene. Photophysical properties of the D-A linked systems were investigated in detail. Time-resolved spectroscopic measurements of the D-A linked systems with systematically tuned linker lengths or dimerized D units revealed that the exciplex state plays a pivotal role in determining the photodynamics of these composites. In addition, we found that the incorporation of nanocarbon materials such as graphene and fullerene into an electron-transporting layer of perovskite solar cells improved the device performance.
