A perylenediimide (PDI) tetramer‐based three dimensional (3D) molecular material, termed SFX‐PDI4, has been designed, synthesized, and characterized. The low‐lying HOMO and LUMO energy levels, high electron mobility and good film‐formation property make it a promising electron transport material (ETM) in inverted planar perovskite solar cells (PSCs). The device exhibits a high power conversion efficiency (PCE) of 15.3% with negligible hysteresis, which can rival that of device based on PC 61 BM. These results demonstrate that three dimensional PDI‐based molecular materials could serve as high performance ETMs in PSCs.
