To enhance the efficiency of polymer solar cells (PSCs), interfacial layer materials have been investigated for the introducing interface dipoles at the cathode interface, which reduces the electron injection/collection barrier between the active layer and the cathode. Polyviologen (PV) derivatives are one of the most promising candidates as interfacial layer materials. Therefore, we investigated the effects of different types counteranions (CAs) on conjugated polymer electrolyres (CPEs) or polyelectrolytes based on a cationic PV derivative as cathode buffer layer. Herein, our results show that the changing CAs in PV derivatives affected the device performance by influencing the strength of interfacial dipoles in PSCs. |
