  • Publication number: 20210043842
    Abstract: An electrode interface layer material is generated by using a modifier to react with polyethyleneimine, and the amine group on the polyethyleneimine is converted into an ammonium group by reacting with the modifier to form a zwitterionic polyethyleneimine. When an active layer containing a non-fullerene material is formed on the surface of the electrode interface layer, or when the surface of the electrode interface layer is contacted with a non-fullerene material, the possibility that the non-fullerene material is destroyed by the amine groups in the electrode interface layer can be reduced. In addition, the aforementioned electrode interface layer material or zwitterionic polymer is used for an organic photovoltaic device.
