Brownian Tree‐Shaped Dendrites in Quasi‐2D Perovskite Films and Their Impact on Photovoltaic Performance (Adv. Mater. Interfaces 13/2022)

Dendrite Formation in Quasi-2D Perovskite Films for Solar Cells In article number 2102231, Fei Zheng, Kenneth P. Ghiggino, and co-workers report that Brownian tree-shaped dendrites that form in quasi-2D perovskite films are beneficial to perovskite solar cell performance. The dendrites are grown by the diffusion-limited aggregation of thicker Ruddlesden-Popper perovskite phase domains resulting in improved film morphology.
