Beschreibung: Interface function material has been widely used to reduce interfacial potential barrier for enhanced charge-dynamics and photovoltaic properties of perovskite solar cells (PSCs). Herein, ternary oxides Fe2-xMgxO3 are introduced to passivate the perovskite/SnO2 quantum dots (QDs) interface. The interaction between perovskite and Fe2-xMgxO3 could trigger a heterogeneous nucleation for the uniform perovskite photoactive layer. The flocculent Fe2-xMgxO3 also increase the interface contact with perovskite enabling more transferring channel of electron, and decrease the interface-defects with smaller the energy level offset at this interface. Such oxide bridges between perovskite and SnO2 QD could effectively enhance electron transfer. Consequently, a Fe1.84Mg0.16O3-based PSC is achieved with a champion efficiency over 21% and negligible J–V hysteresis
