Abstract

This work investigates the structural, morphological, and compositional characteristics of PCDTBT : PC71BM blends with varying PC71BM ratios have been fabricated using co-solvent (chloroform and chlorobenzene) to optimize their performance in organic photovoltaic (OPV) applications. The samples were made by spin coater on a glass substrate that had been previously cleaned. The X-ray diffraction (XRD) patterns shows a broad peak around 23°, revealing the amorphous nature of the blends. Atomic force microscopy (AFM) of samples with varying concentrations of PC71BM reveals that an increase in PC71BM composition may cause aggregates to form on the blended film. Additionally, the elemental distribution throughout the blends was revealed by energy dispersive spectroscopy (EDS), which verified the aggregation of PC71BM at various concentrations. This thorough investigation shows that the PC71BM content significantly impacts the blend’s shape and composition.
