在有机太阳能电池（OSC）领域，串联结构器件在提高功率转换效率（PCE）方面表现出非常有吸引力的优势。除了不同子电池中经过充分研究的新型有源层对之外，互连层（ICL）的构造在实现高性能串联器件中也发挥着关键作用。在这项工作中，采用一种新的方法来实现环境友好的溶剂处理聚合物 ICL 聚[(9,9-双(3'-(N,N-二甲基氨基)丙基)-2,7-芴)-alt-5,5'-双(2,2'-噻吩)-2,6-萘-1,4,5,8-四羧基-N,N'-二(2-乙基己基)亚胺] 据报道，（PNDIT-F3N）与聚（乙烯亚胺）（PEI）共混作为电子传输层（ETL）和PEDOT：PSS作为空穴传输层。研究发现，PNDIT-F3N 对 PEDOT 的修饰能力可以通过 PEI 的掺入进行线性调节，这为研究 ICL 中的电荷复合行为提供了机会。最终实现了最高 PCE 为 12.6% 的串联 OSC，这是迄今为止报道的最好的串联 OSC 之一。这些结果为在高性能串联OSC中构建高效ICL提供了新的选择，并指导了用于ICL构建的新型ETL材料的设计方法，甚至可以集成到未来的印刷柔性大面积模块器件制造中，具有环保溶剂处理和厚度不敏感的优点。
In the field of organic solar cells (OSCs), tandem structure devices exhibit very attractive advantages for improving power conversion efficiency (PCE). In addition to the well researched novel pair of active layers in different subcells, the construction of interconnecting layer (ICL) also plays a critical role in achieving high performance tandem devices. In this work, a new way of achieving environmentally friendly solvent processed polymeric ICL by adopting poly[(9,9‐bis(3′‐(N,N‐dimethylamino)propyl)‐2,7‐fluorene)‐alt‐5,5′‐bis(2,2′‐thiophene)‐2,6‐naphthalene‐1,4,5,8‐tetracaboxylic‐N,N′‐di(2‐ethylhexyl)imide] (PNDIT‐F3N) blended with poly(ethyleneimine) (PEI) as the electron transport layer (ETL) and PEDOT:PSS as the hole transport layer is reported. It is found that the modification ability of PNDIT‐F3N on PEDOT can be linearly tuned by the incorporation of PEI, which offers the opportunity to study the charge recombination behavior in ICL. At last, tandem OSC with highest PCE of 12.6% is achieved, which is one of the best tandem OSCs reported till now. These results offer a new selection for constructing efficient ICL in high performance tandem OSCs and guide the way of design new ETL materials for ICL construction, and may even be integrated in future printed flexible large area module device fabrication with the advantages of environmentally friendly solvent processing and thickness insensitivity.
