Fig. 6: Morphology evolution of BHJ films.
From: Lifetime over 10000 hours for organic solar cells with Ir/IrOx electron-transporting layer
The two-dimensional (2D) grazing incidence wide-angle X-ray diffraction (GIWAXS) patterns of fresh (a) and aged (b) PM6:Y6 film on ZnO; fresh (c) and aged (d) PM6:Y6 film on Ir/IrOx. The comparison of coherence length (CCL) (e), Flory-Huggins parameters (χ), and ___domain size (d) (f) of fresh and aged BHJ films on ZnO and Ir/IrOx electron-transporting materials. In f, the bars correspond to the χ parameters and the dots correspond to the d parameters extracted from the grazing incidence small angle X-ray scattering (GISAXS).
