| Outline of Final Research Achievements |
Carrier highway films, i.e., single crystalline films of high hole-mobility organic semiconductor and a high electron-mobility organic semiconductor were fabricated. Lateral extraction of photogenerated holes and electrons of the order of 1 mm was demonstrated in the hole and electron highway. Operation of super-bulkheterojunction cells combining the hole and electron highway, which can be regarded as a new type of organic tandem solar cell, was demonstrated. Hall effect measurements of the doped organic single crystals were succeeded for the first time. The present results have the meaning of dawn of organic single crystal electronics such as high performance organic single crystal solar cells.
