Interfacial layer has a significant impact on the achievement of highly efficient organic–inorganic hybrid perovskite solar cells(PSCs).Here,we introduced a nano-ZnMgO(magnesium doped ZnO,abbreviated as ZnMgO)as interfacial layer between[6,6]-Phenyl C61 butyric acid methyl ester(PC61 BM)layer and Al electrode to replace LiF or ZnO interlayer and enhance device performance.The device efficiency has been improved from 11.43%to 15.61%and the hysteresis was decreased dramatically.Such huge enhancement of power convert efficiency(PCE)can be attributed to the low dark current density,enhancement of electron-selective contact,and low energy barrier at the PC61 BM/Al interface.We suggest that this simple nano-scale interlayer can provide an efficient charge transport and extraction for highly efficient PSCs. 展开更多
