Outline of Final Research Achievements |
P-type lod-shape molecules were deposited in vacuum on conductive polymer films, in which polymer chains were oriented parallel to the substrate planes formed by the friction transfer method, resulting in the formation of the oriented lod-shape molecular films parallel to the direction of the oriented polymer chains. Then, n-type lod-shape molecules were deposited on the oriented p-type lod-shape molecules, p-n and p-i junction layers, in which both n-type and p-type lod-shape molecules were oriented parallel to the substrate planes, were fabricated. Organic photovoltaic device performance based on these oriented layers as active layers was higher than that based on non-oriented layers parallel to the substrate planes, showing that orientation control of both p-type and n-type lod-shape molecules in these layers parallel to the substrate planes leads to anisotropic electronic physical properties of these layers.
