We fabricated highly-oriented thin films of 3,4,9,10- perylenetetracarboxylic-bis-benzimidazole (PTCBI), poly(9,9-dioctyl-fluorene) (PFO) and regioregular poly(3-hexylthiophene) (P3HT). Each material was aligned by the rubbing process, and high dichroic ratio of 4-6 was achieved. We also investigated application for organic p-n heterojunction type photovoltaic devices, which include the aligned layer. Aligned-PTCBI (n-type) stacked with unaligned-TiOPc (p-type) showed good photovoltaic performance equal to the conventional unaligned stacked devices. High power conversion efficiency of 0.8% was achieved.
