In article number 1700522 , Xiao Wei Sun, Qichun Zhang, and co‐workers report the design and synthesis of a new n‐type small molecule with a sulfur‐containing structure. Employing this small molecule as electron transport layer (ETL), highefficiency planar perovskite solar cells up to 18.1% are realized. This superior performance is mainly due to effective suppression of charge recombination at the perovskite/ETL interface.
