Abstract
Incorporation of bilayer electrodes (Cu:Ag) significantly reduces electrode corrosion and device degradation in perovskite solar cells operating in air. A symbiosis exists whereby Ag inhibits Cu oxidation and Cu prevents interfacial reactions between the perovskite (MAPbI<sub>3</sub>) and Ag.
