Abstract
A polymeric ionic liquid (PIL) was synthesized from a small-molecule one (MIL, the monomer), and they were used as cathode interlayers in organic solar cells. Compared with the MIL, the PIL can form a more uniform film for full coverage of an active layer and efficient cathode modification, resulting in higher device efficiency and reproducibility.
