Perovskite solar cells with atomically coherent interlayers on SnO2 electrodes

Nature, Published online: 20 October 2021; doi:10.1038/s41586-021-03964-8

An atomically coherent interlayer between the electron-transporting and perovskite layers in perovskite solar cells enhances charge extraction and transport from the perovskite, enabling high power conversion efficiency.
