Probing molecular orientation of donors and acceptors in all-polymer blend films by near-edge x-ray absorption fine structure spectroscopy

open access: yesJPhys Materials
The molecular orientation is crucial for the efficiency of organic solar cells. A face-on orientation, in which the $\pi - \pi $ stacking direction is oriented perpendicular to the substrate, is typically preferred because it enhances vertical charge ...
