文摘
- •
Perovskite solar cells with different cathode of Al, Ag and AgAl were fabricated.
- •
Cells with AgAl alloy retained 90% of the initial PCE values after aging 48 h.
- •
Cells with AgAl kept the initial Voc during aging 360 h, showing amazing stability.
- •
The superior stability of cells with AgAl is attributed to the formation of AlOX.
- •
AlOX formed boosts electron extraction and inhibits moisture encroachment.
