Background: This invention provides a new polymeric interlayer material that can greatly enhance the power conversion efficiency (PCE) of organic or polymer solar cells. Applications: 1) High performance organic/polymer solar cells 2) High performance organic/polymeric electronic materials such as polymeric light emitting materials
1) Enhances the PCE of polymer solar cells by more than three fold 2) Tolerant to variations in interlayer thickness 3) Maintains high PCE values for interlayer thickness exceeding 20 nm 4) Amenable to flexible electronics
