3D structured small molecule acceptors with imide-linked perylene diimides on a 9,9’-spirobifluorene core for non-fullerene organic solar cells |
| 초록 |
Three-dimensional (3D) propeller-shaped small molecule acceptors containing imide-linked perylene diimides (iPDI) on a 9,9'-spirobi[9Hfluorene] core were designed, synthesized and characterized for non-fullerene solar cells. The best power conversion efficiency of 5.31% and 4.68% were obtained using SF-iPDI2 and SF-iPDI4, respectively, in a solution-processed bulk heterojunction solar cell when blended with the conjugated donor polymer PTB7-Th. These results demonstrate that PDI derivatives with 3D molecular structures could serve as high-performance electron acceptors in non-fullerene solar cells. |
