Novel dithiafulvenyl (DTF)‐naphthalenediimide (NDI) derivatives DS1 and DS2 has been designed, synthesized and characterized. To replace the costly PCBM in inverted perovskite solar cells (PSCs), we here propose these materials. DS1 and DS2 were employed as electron transport layers (ETL) to fabrica...
