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.
