Thermal and optical properties of P3HT:PC70BM:ZnO nanoparticles composite films

X-Ray diffraction

In order to examine the presence of ZnO-NPs in composite films, impact of thermal annealing and to determine the effect of the polymer molecular weight on the microstructure of composite films, we conducted detailed X-ray diffraction studies, which included powders of purchased materials and films obtained from their mixtures with an increasing number of individual components. Namely: ZnO nanoparticle powder and one-component P3HTi (i = 1–3) and PC70BM powders and films; two-component films P3HTi + PC70BM70 and P3HTi + ZnO-NPs; and ternary composite films…
