Performance and Stability of Polymer:Nonfullerene Solar Cells with 100 °C‐Annealed Electron‐Collecting Combination Layers

Invited for this month′s cover is the group of Youngkyoo Kim at the Kyungpook National University. The image shows the improved electron transfer by hybrid combination layers featuring peculiar morphology for better efficiency and stability in polymer solar cells. The Full Paper itself is available at 10.1002/cssc.202100841. “Polymer solar cells have great potential for next‐generation solar cells…” This and more about the story behind the research that inspired the Cover image is presented in the Cover Profile.
