摘要
Electron transporting layer（ETL）materials have attracted much attention in recent years in the research fields of organic/polymer solar cells（OSCs/PSCs）and planar perovskite solar cells（pero-SCs）,because ETL materials play very important role in improving the photovoltaic performance of devices.Among the ETL materials reported in literatures,conjugated polymer poly[（9,9-bis（3＇-（N,N-dimethylamino）propyl）-2,7-fluorene）-alt-2,7-（9,9-dioctylfluorene）]（PFN）show good film-forming property and excellent device performance for the small area PSCs.But the ETL of PFN
