| Outline of Final Research Achievements |
A new technique for the fabrication of organic polycrystalline thin films by a thermal annealing of amorphous thin films was developed. Organic field effect transistors (OFETs) using the polycrystalline films showed ca. 70-times larger mobilities as compared with OFETs using the amorphous thin films. A new method for the fabrication of interpenetrating network (IPN)-like structures by using the fluidity of super-cooled liquids obtained by heating of amorphous solids above the glass-transition temperatures was developed. Implementation of the IPN-like structures in organic solar cells improved the short-circuit current densities and fill factors, thus improved the power conversion efficiencies.
