2D Ruddlesden–Popper Perovskite with Ordered Phase Distribution for High‐Performance Self‐Powered Photodetectors (Adv. Mater. 35/2021)

Perovskite Photodetectors In article number 2101714, Wei Tian, Liang Li, and co-workers report a practical method to adjust the phase distribution in 2D Ruddlesden–Popper perovskites to construct efficient and stable perovskite photodetectors. The ordered arrangement of phase compositions facilitates the separation and transportation of photogenerated charge carriers, and endows the device with improved performance and environmental stability.
