| 英文摘要 | Three solution-processable small molecules of DPPT, DPPSe and DPPTT were synthesized by Stille coupling through attaching donor units of thiophene (T), selenophene (Se) and thieno[3,2-b] thiophene (TT) to the diketopyrrolopyrrole (DPP) core, respectively. Replacement of the T donors with the more polarized Se units results in a balance between the a and b direction packing and an obvious increase of the power conversion efficiency (PCE) from 1.90% to 2.33% with the increase of the short-circuit current (I-sc) from 5.59 to 5.81 mA cm(-2) and the open-circuit voltage (V-oc) from 0.78 V to 0.86 under the small molecule/acceptor ratio of 3:1. However, introduction of the conjugation-enlarged TT groups (versus the T units) leads to a decrease of the PCE, down to 1.70%, with a significant decrease of the fill factor (FF) (38% versus 44%), due to its poor film-forming characteristics. |
