Frontispiece: Molecular Design of A−D−A Electron Acceptors Towards Low Energy Loss for Organic Solar Cells

To achieve high photovoltaic efficiency in organic solar cells, low energy loss is especially important. Electron-vibration coupling plays a significant role in reducing the energy loss. Read more about recent theoretical advances on revealing the energy loss mechanisms at the molecular level in the Concept article by L. Zhu, Y. Yi et al. (DOI: 10.1002/chem.202203356).
