提出了一种制备聚合物太阳电池有源层的新方法，该方法无需热后处理即可获得最佳性能。聚(3-己基噻吩基)(P3HT)纳米纤维是在高浓度溶液中得到的，这使得在不同的衬底上制备纳米结构薄膜成为可能。在这里，详细介绍了这些纤维的制备以及它们在溶液和固态中的表征。通过将这些纳米纤维与分子受体如[6，6]-苯基C-61-丁酸甲酯(PCBM)混合在溶液中，可以在简单的工艺中获得用于有机太阳能电池的高效有源层，其功率转换效率(PCE)高达3.6%。这里开发的室温工艺与常用塑料衬底的兼容性可能导致诸如开发大面积柔性太阳能电池的应用。
A new method for the preparation of active layers of polymeric solar cells without the need for thermal post-treatment to obtain optimal performance is presented. Poly (3-hexylthiophene) (P3HT) nanofibers are obtained in highly concentrated solutions, which enables the fabrication of nanostructured films on various substrates. Here, the preparation of these fibers along with their characterization in solution and in the solid state is detailed. By mixing these nanofibers with a molecular acceptor such as [6,6]-phenyl C-61-butyric acid methyl ester (PCBM) in solution, it is possible to obtain in a simple process a highly efficient active layer for organic solar cells with a demonstrated power conversion efficiency (PCE) of up to 3.6%. The compatibility of the room-temperature process developed herein with commonly used plastic substrates may lead to applications such as the development of large-area flexible solar cells.
