第三组分在聚合物太阳能电池(PSCs)中发挥着越来越重要的作用，尤其是对形态的影响。在这里，我们使用三元聚合物施主(TBFCl50-BDD)和有机小分子受体(BTP-4F)作为主要材料，并引入第三组分(PC71BM)来增强光活性层的形貌，从而改善器件的性能。基于TBFCl50-BDD：BTP-4F的PSCs的效率仅为10.58%，而三元器件(TBFCl50-BDD：BTP-4F：PC71BM)的功率转换效率达到13.15%。重要的是，PC71BM的引入不仅可以改善活性层的形貌，促进激子更有效的传输，而且还可以影响分子的排列，从而获得更好的结晶性能。本工作为优化PSCs的形貌以提高其性能提供了一种有效的方法。
The third component played an increasingly significant role in polymer solar cells (PSCs), especially for the morphological impact. Here, we use a ternary polymer donor (TBFCl50-BDD) and organic small molecule acceptor (BTP-4F) as the main material and introduce a third component (PC71BM) to enhance the morphology of the photoactive layer and result in improved device performance. The TBFCl50-BDD:BTP-4F based PSCs only exhibited an efficiency of 10.58%, while The power conversion efficiency of ternary device (TBFCl50-BDD:BTP-4F:PC71BM) reached 13.15%. Importantly, the introduction of PC71BM can not only improve the morphology of the active layer and promote more efficient exciton transport, but also influence the molecular arrangement for better crystallization performance. This work offers an effective method for optimization of the morphology to enhance the properties of PSCs.
