文章亮点

  • (1) 合成了两种具有不同长度侧链的非对称的六元稠环小分子受体，BP4F-HU和BP4F-UU。
  • (2) 基于PM6:BP4F-UU的器件相较于PM6:BP4F-HU（0.863 V）表现出0.878 V的高开路电压。
  • (3) 合成了一种新的宽带隙小分子受体，BTP-TA，三元器件PM6:BP4F-UU:BTP-TA达到了17.83％的最佳光电转化效率。
  • 有机太阳能电池(OSCs)作为一种新型清洁光伏技术，因其具有质量轻、柔性和可溶液法加工等优点受到广泛关注。精细分子设计与器件工艺优化之间的协同作用为实现OSCs中开路电压（Voc）、短路电流密度（Jsc）和填充因子（FF）之间的平衡提供了可能途径，从而进一步推动高效有机光伏器件的发展。在此，合成了两种非对称的六元稠环小分子受体（SMAs），命名为BP4F-HU和BP4F-UU。BP4F-UU分子中外侧烷基链的延伸限制了其末端基团的旋转，降低了混合薄膜中的能量失序，进而减少了器件中的能量损失。同时，BP4F-UU分子中π–π堆积的增强提高了薄膜的电荷迁移率。基于PM6:BP4F-UU的器件相较于PM6:BP4F-HU（0.863 V）表现出0.878 V的高Voc。此外，设计合成了一种与PM6:BP4F-UU二元体系具有互补吸收的新的宽带隙SMA，命名为BTP-TA。由于BTP-TA的光致发光（PL）光谱与BP4F-UU的吸收光谱之间有良好的重叠，BTP-TA与BP4F-UU之间可以通过荧光共振能量转移（FRET）途径实现有效的分子间能量转移。宽带隙第三组分BTP-TA的加入进一步提高了器件的Voc。最终，含有15wt％BTP-TA的三元器件PM6:BP4F-UU:BTP-TA实现了Voc（0.905 V）、Jsc（26.14 mA/cm2）和FF（75.38％）的同时提高，达到了17.83％的最佳PCE。这项工作表明，分子结构设计与器件工艺优化的协同策略是提高有机太阳能器件光伏性能的有效方法。

    Alkyl chain modulation of asymmetric hexacyclic fused acceptor synergistically with wide bandgap third component for high efficiency ternary organic solar cells

      Abstract
    • Herein, two asymmetric hexacyclic fused small molecule acceptors (SMAs), namely BP4F-HU and BP4F-UU, were synthesized. The elongated outside chains in the BP4F-UU molecule played a crucial role in optimizing the morphology of blend film, thereby improving charge mobility and reducing energy loss within the corresponding film. Notably, the PM6:BP4F-UU device exhibited a higher open-circuit voltage (Voc) of 0.878 V compared to the PM6:BP4F-HU device with a Voc of 0.863 V. Further, a new wide bandgap SMA named BTP-TA was designed and synthesized as the third component to the PM6:BP4F-UU host binary devices, which showed an ideal complementary absorption spectrum in PM6:BP4F-UU system. In addition, BTP-TA can achieve efficient intermolecular energy transfer to BP4F-UU by fluorescence resonance energy transfer (FRET) pathway, due to the good overlap between the photoluminescence (PL) spectrum of BTP-TA and the absorption region of BP4F-UU. Consequently, ternary devices with 15wt% BTP-TA exhibits broader photon utilization, optimal blend morphology, and reduced charge recombination compared to the corresponding binary devices. Consequently, PM6:BP4F-UU:BTP-TA ternary device achieved an optimal power conversion efficiency (PCE) of 17.83% with simultaneously increased Voc of 0.905 V, short-circuit current density (Jsc) of 26.14 mA/cm2, and fill factor (FF) of 75.38%.
