제목 Nano-Confinement Effect on Conductive Polymers and Its Application to Organic Solar Cells
초록 In the present study, we employed scalable nano-imprinting lithography as a method to change the molecular orientation by exploiting nano-confinement and also studied its application to organic solar cells. We fabricated nanorods of conductive polymers with different chemical structure, dimension, and crystallinity based on patterning with AAO templates. GIWAXS measurements showed different chain orientation and crystallinity different from bulk crystallinity. We adopted P3HT nanorods with face-on orientation for the ordered heterojunction organic solar cell architecture. We were able to control both chain orientation and domain size of organic solar cells with patterned nano-imprinted of P3HT nanorods coupled with thermal annealing to control the mutual diffusion between P3HT and PCBM. Finally, we optimized the morphology of ordered organic solar cells and obtained more than 5 times higher power conversion efficiency than bilayer organic solar cells.
