报告内容摘要：
The structure and architecture of polymer solar cells on scales from nm to mm have crucial impact for the device performance. With standard X-ray scattering techniques, we may determine donor and acceptor domain sizes in polymer solar cells, crystalline structure and characterize the dimensionality of the interface, but to quantify the capability of the nanostructure for separating electron-hole pairs and for transporting free charges, we need access to the 3D structure on the nm scale. X-ray ptychography has the potential to allow these investigations, and has the further advantage that it is a reasonably “mild” technique, due to the weak interaction of X-rays with the material. We have carried out very promising feasibility studies, where we with reasonable ease approach a 100 nm spatial resolution, and with clear pathways for improving resolution below 10 nm. |
