摘要
由于聚合物太阳能电池的光活性层通常采用溶液旋涂的方式进行加工,溶剂的合理选择对于获得理想形貌以及较高的能量转化效率至关重要。我们率先使用新型非卤溶剂邻甲基苯甲醚制备聚合物太阳能电池。对于给受体为PBDT-TS1/PC_(71)BM聚合物太阳能电池,在无需添加剂和其他后处理的情况下,使用邻甲基苯甲醚制备的器件可获得高达9.67%的能量转换效率。这一结果不仅与该材料在传统二元体系(二氯苯/1,8-二碘辛烷)下所得结果相当。此外,将这种加工方法应用于另一种经典的PTB7-Th材料上,也获得了同二元体系下相当的效率。原子力显微镜和透射电镜对薄膜形貌的研究结果表明,使用邻甲基苯甲醚可以获得与传统二元体系相似的活性层形貌。这项研究表明完全可以使用绿色的单一溶剂代替传统的二元体系制备高效聚合物太阳能电池,这为寻找新型加工溶剂及简化加工工艺提供了新的思路。
The development toward simplifying processing method and reducing the toxic in production is of significance in promoting the application of polymer solar cells(PSCs). In this study, we firstly proposed a novel environment-friendly processing solvent 2-methylanisole(MA) to fabricated PBDT-TS1:PC_(71)BM-based PSCs, and then a power conversion efficiency(PCE) as high as 9.67% was realized under the additive- and posttreatment-free circumstance, which is similar as the reported results obtained from the PSCs processed by the halogenated DCB/DIO processing system. As far as we known, it is the record PCE among PSCs fabricated from single-solvent system. Atomic force microscopy and transmission electron microscopy images suggested that an ideal morphology similar to those of binary-solvent-processed films can be obtained via MA, which resulted in the high PCE. This work reveals a possibility of replacing binary halogenated system with single halogen-free solvent to fabricate highly efficient PSCs.
