Tin dioxide (SnO2) has been widely applied as an electron transport layer (ETL) for the n-i-p-type perovskite solar cells (Pero-SCs). However, existence of defects at surface SnO2 and hysteresis behavior devices with ETL limit its application in Pero-SCs. In this study, a fullerene derivative pyrrolidinofullerene C60-substituted phenol (NPC60-OH) was synthesized to modify Pero-SCs first time. The systematic comparative characterizations demonstrated that, after introduction NPC60-OH...
