| Outline of Final Research Achievements |
In this research, we tried to elucidate how interface structure impacts energy structure at organic heterojunctions. We found at first that the orientation of side chain f PC61BM, which is the acceptor material for organic photovotalics (OPVs), drastically changes upon crystallization of PC61M thin film. 6T film on the PC61BM exhibits wider terraces that that on as-coated PC61BM film due to the increased surface energy. We also found that F16CuPc/6T interface, where both materials are crystalline, has significant disordering/intermixing upon the interface formation, which revealed by X-ray diffraction and scanning tunneling microscopy. That observation reasonably explains the origin of the complex energy level alignment at the donor/acceptor interface.
