Effect of Polyviologen Derivatives as the Buffer Layer on the Photovoltaic Properties of Polymer Solar Cells |
| 초록 |
Highly efficient and stable polymer solar cells (PSCs) have been fabricated by introducing interface dipoles at the cathode interface as a cathode buffer, which can greatly improve device performance by influencing the strength of interfacial dipoles in PSCs. By choosing suitable interfacial materials, the energetic barrier height at the interface could be reduced to form an ohmic contact with less series resistance, inducing high charge collection efficiency of the corresponding electrodes for holes or electrons. In this paper, we investigated the different types counteranions (CAs) on conjugated polymer electrolytes (CPEs) or polyelectrolytes based on a cationic polyviologen (PV) derivative as cathode buffer layer. The strength of interfacial dipoles in PSCs is affected by changing the CAs in PV derivatives. |
