- •
An innovative structure of PSCs has been designed by accurately inserting Al2O3 layer at ZnO/perovskite interface.
- •
The thickness of Al2O3 layer is optimized by a quantum tunneling model based on effective-mass approximation theory.
- •
The highest efficiency up to 15.55% is obtained and the average PCE is considerably increased by 44%.
- •
The application of Al2O3 layer simultaneously enhances both stability and efficiency of PSCs.
