3D electron diffraction—the missing slice completing nanoscale analysis of organic solar cells in TEM (opens in new tab)

Optimizing the performance of organic solar cells hinges on a comprehensive understanding of their nanostructures, yet traditional characterization methods often fall short, delivering incomplete structural snapshots. We introduce elastically filtered 3D electron diffraction as technique to bridge full reciprocal- and real-space structural analysis within a single transmission electron microscope. Using model bulk heterojunction DRCN5T:PC71BM, 3D electron diffraction reproduces key structural...
