摘要合成了两种新的非富勒烯受体（nfa），用于有机太阳能电池（OSC）。Isatin相关的弱吸电子部分与吲哚二噻吩偶联，得到了能量水平升高的新nfa，特别是LUMO水平。nfa被设计成与宽带隙给体聚合物配对，以减少能量损失（loss），从而在有机太阳能电池中实现高开路电压（Voc）。以新NFAs为受体的OSC器件的Voc高达1.18 V。高开路电压是通过小损耗实现的。
Abstract Two new non-fullerene acceptors (NFAs) have been synthesized for organic solar cell (OSC) applications. Isatin related weak electron withdrawing moieties were coupled with indacenodithiophene to give new NFAs with elevated energy levels, especially the LUMO levels. The NFAs were designed to pair with wide band-gap donor polymers for reducing energy loss (Eloss) and therefore achieving high open circuit voltages (Voc) in organic solar cells. The OSC devices with the new NFAs as acceptors showed the Voc as high as 1.18 V. The high open circuit voltages were achieved via small Eloss.
