| 英文摘要 | Two new non-fullerene acceptors, IDTC and IDTO, were designed and synthesized for the application in organic solar cells (OSCs). Compared with IDTC, the introduction of electron-donating alkoxy groups of IDTO leads to a higher LUMO level with a slightly blue-shifted absorption. Using the polymer PBDB-T as donor arid the two small molecules as acceptors in the conventional device structure, the IDTC-based OSC exhibits a power conversion efficiency (PCE) of 9.35% with an open-circuit voltage (V-oc ) of 0.917 V, a short-circuit current density (J(sc) ) of 16.56 mA cm(-2) , and a fill factor (FF) of 61.61%. For the OSC based on IDTO, a higher PCE of 10.02% with a V (oc) of 0.943 V, a J(sc) of 16.25 mA cm(-2) , and an FF of 65.41% are obtained. The more balanced mu(e)/mu(v) evident aggregation, and phase separation contribute to the higher FF for the device based on IDTO The increased J(sc) for the device based on PBDB-T:IDTC can be attributed to the red-shifted and stronger absorption of the PBDB- |
