Synthesis and characterization of fullerene-free acceptors for organic solar cells |
| 초록 |
Perylene diimide (PDI) based three acceptors are synthesized for use in fullerene-free organic solar cells. The two PDI rings are connected to the end of the n-type core, forming a PDI-n-type core-PDI structure. The introduction of alkyl side chains onto the n-type core structure weakened the intermolecular interaction, whereas fluorination of the n-type core structure improved the backbone planarity and intermolecular ordering. The planar core structure without bulky alkyl chains yielded the best power conversion efficiency, 4.41%, when mixed with PTB7-Th donor. The n-type core structure was beneficial in terms of increasing the electron accepting properties and the absorption in the high bandgap region of non-fullerene acceptors. |
