<p><P>PROBLEM TO BE SOLVED: To provide an organic thin film solar battery in which a photoelectric conversion layer where a high mobility organic semiconductor material excellent in carrier transport property and fullerene are uniformly blended can be formed, and which is superior in conversion efficiency and durability. <P>SOLUTION: In the organic thin film solar battery, the photoelectric conversion layer 3 where a p-type organic semiconductor and an n-type organic semiconductor are blended is arranged between two electrodes 4 and 5 either of which is optically transparent. In the photoelectric conversion layer 3, the p-type organic semiconductor is formed of oligothiophene, the n-type organic semiconductor is formed of fullerene, and a volume rate of fullerene is 60% or more. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
