Solar cell performance and morphology characterization of a diketopyrrolopyrrole-based low bandgap polymer is reported. The polymer adopts an H-type aggregation and solvent mixture processing gives a better morphology. The morphology evolution is characterized by combined GIXD and GISAXS experiments and a four step morphology development mechanism is proposed.
报道了一种基于二酮吡咯并吡咯的低带隙聚合物的太阳能电池性能和形貌表征。该聚合物采用 H 型聚集，溶剂混合处理可获得更好的形貌。通过结合 GIXD 和 GISAXS 实验对形貌演变进行了表征，并提出了一个四步形貌发展机制。
