摘要

全聚合物太阳能电池(all-PSCs)由于其长期的稳定性和优异的薄膜拉伸性,近年来引起了广泛的关注并取得了重大进展。然而,由于聚合物链的高度纠缠,体积异质结(BHJ)薄膜的形貌控制问题阻碍了器件性能的进一步提高。在这项工作中,我们通过空间效应诱导的微观结构重建获得了微调的光活性层形态,从而实现了三元全pscs器件性能的提高。萘二亚胺-吲哚二噻吩基共聚物受体BL-102主链上的大四己基苯基取代基产生空间位阻效应,影响分子间相互作用。因此,共聚物BL-102具有抑制自聚集的特性,从而在共混膜中重建晶体特征和形态。三元装置倾向于通过抑制原始聚合物的聚集来减少过度相分离,但促进混合行为。因此,最佳的BHJ薄膜具有较大的π -π堆叠相干长度和有序的面朝分子取向,呈现出结构良好的双连续互穿纳米网络。因此,可以实现更快的电子转移(ET)和空穴转移(HT)过程,并结合平衡的载流子迁移率,从而提高器件的整体性能。本研究提供了一种通过结构位阻效应来调控全聚能干细胞光活性层形态的有效方法,并证明了三元共混策略诱导的纳米级形态调制对于制备高效全聚能干细胞的意义。

Crystallinity and phase separation induced morphological modulation for efficient ternary all-polymer solar cells
All-polymer solar cells (all-PSCs) have attracted enormous attention and achieved significant progress in recent years due to their long-term stability and excellent film stretchability. However, the problem of morphology control in bulk-heterojunction (BHJ) films due to highly entangled polymeric chains hinders the further improvement of device performance. In this work, we obtained fine-tuned photoactive layer morphology through reconstructed microstructure induced by steric effects to realize an improved device performance in ternary all-PSCs. The large tetrahexylphenyl substituents on the backbone of naphthalene diimide–indacenodithienothiophene based copolymer acceptor BL-102 bring forth the steric-hindrance effect and influence intermolecular interactions. Therefore, the copolymer BL-102 delivers the property of suppressed self-aggregation, causing reconstructed crystalline features and morphology in blending films. The ternary devices tended to reduce the excessive phase separation by suppressing the aggregation of original polymers but to promote intermixing behaviors. Therefore, the optimal BHJ film manifested a well-formed bi-continuous interpenetrating nanoscale network with a larger π–π stacking coherence length and ordered face-on molecular orientation. Hence, a faster electron transfer (ET) and hole transfer (HT) process combined with balanced charge carrier mobilities can be achieved to enhance the overall device performance. This work provides an effective method to regulate the photoactive layer morphology of all-PSCs through structurally steric hindrance effects and demonstrate the significance of ternary-blending strategy induced nanoscale morphology modulation for fabricating highly efficient all-PSCs.
