Beschreibung
Zusammenfassung:	A zwitterionic electrode interface layer material, a zwitterionic polymer, and an organic photovoltaic device comprising the zwitterionic electrode interface layer material or the zwitterionic polymer are disclosed. The zwitterionic electrode interface layer material of the present invention comprises a cation group and an anion group. The cationic group is secondary ammonium, tertiary ammonium, or quaternary ammonium, and is formed from polyethyleneimine grafted and modified by fullerene derivatives. The polyethyleneimine grafted and modified by fullerene derivatives is prepared by reacting a fullerene derivative, a modifier, and polyethyleneimine. The zwitterionic electrode interface layer material (zwitterionic polymer) of the present invention can improve the power conversion efficiency (PCE) of the organic photovoltaic device.
