摘要

In article no. 1900192, Ai Ping Chen, Shuang Yang, Yu Hou, and co‐workers employ a versatile alkaline earth metals doping strategy to engineer the electronic structure of NiOx contacts for inverted planar perovskite solar cells, in which the champion device demonstrates a power conversion efficiency of 19.49% with a high open circuit voltage of 1.14 V. Alkaline earth metals doping can significantly optimize the electrical properties by deepening the valence band maximum and enhancing the hole conductivity.
