A Solution-Processed Cathode Interfacial Layer for Efficient Energy Level Alignment in Organic Photovoltaics: Synthesis and Characterization |
| 초록 |
We synthesized a small-molecule interfacial material and used it as a cathode interfacial material in organic photovoltaics (OPVs). The new small-molecule interfacial material was designed to induce strong interface dipole and to have chelations with metal electrodes. It can be dissolved in various organic solvents for solution processing. We used isopropanol as environmentally benign solvent to dissolve the small-molecule interfacial material and spin coated the solution on photoactive layers. Therefore, the interfacial material led to ohmic contacts between the electron acceptor materials and cathode in OPVs. The promising photovoltaic performances of OPVs indicates that this material can be a promising candidate for the photovoltaic applications. |
