摘要

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.
