Perovskite solar cells with atomically coherent interlayers on SnO2 electrodes

Hanul Min et al.

Summary: By introducing an interlayer between the electron-transporting and perovskite layers in perovskite solar cells, researchers have successfully enhanced charge extraction and transport from the perovskite, leading to higher power conversion efficiency and fewer interfacial defects. The coherent interlayer allowed the fabrication of devices with a certified efficiency of 25.5%, which maintained about 90% of its initial efficiency even after continuous light exposure for 500 hours. The findings provide guidelines for designing defect-minimizing interfaces in metal halide perovskites and electron-transporting layers.
