2D Sn 2+ ‐Based Perovskites In article number 2204870, Yong‐Young Noh and co‐workers demonstrate the high doping efficiency of halide perovskites using a simple molecular charge transfer approach and provides a new opportunity for employing 2D perovskites in high‐efficiency optoelectronic devices. A thin p‐type dopant layer, F4‐TCNQ and MoO 3 , deposited using thermal evaporation improves the control of damage‐free electronic doping. The efficient charge transfer without deterioration of the perovskite microstructure improves the Hall mobility up to 100 cm 2 V −1 s −1 .
