| 제목 | Design and Synthesis of a Non-fullerene Acceptors Introducing Rhodanine-derivate End Group for High Performance Organic Solar Cells |
| 초록 | Nowadays, Organic Solar Cells (OSCs) based on non-fullerene acceptors (NFAs) have achieved rapid development, with outstanding power conversion efficiencies (PCEs) of over 18%. To further improve the performance of the OSCs, it is one of the most effective ways to fabricate a ternary OSCs (TOSCs) that currently records a high PCEs from many advantages such as high charge mobility, broadened light absorption spectrum and improved morphology property. In this study, we designed and synthesized two non-fullerene acceptors introducing rhodanine-derivates as end group to enhance performance of TOSCs. By adding third components to the binary active layer composed of the PM6:Y6 blend, it was possible to adjust optical absorption spectrum and energy level. The devices which introduced a newly designed acceptors achieved excellent short circuit current density, fill factor, open-circuit voltage. As a result, we approached higher PCEs from TOSCs devices compared to binary ones. |
