| Research Abstract |
(1) A grazing-incidence small-angle/wide-angle X-ray scattering (GISAXS/GIWAXS) measurement system was established for organic polymer thin films by using an undulator-type synchrotron light source and a small-angle optical scattering system as a nano-scale structure evaluation system. (2) In thin films of blends of a poly(3-alkylthiophene) (P3AT) and a fullerene derivative (FD), P3HT chains form crystals/amorphous and the FDs form nano clusters in the amorphous state. For the blend films having different photoelectric conversion efficiency, crystallite size of the edge-on type crystal and the in-plane interfacial topography of the blend films were evaluated on the basis of GISAXS patterns. As a result, it was indicated that the photoelectric conversion efficiency became larger with increasing the crystallite size. Also, it was suggested that the in-plane interface topography of the blend films might correlate with the photoelectric conversion efficiency.
