Al-based amorphous metal alloy (i.e. metallic glass) is fabricated into thin film electrode for organic solar cell. The chemical stability of the amorphous alloy thin film is analyzed via electrochemical analyses, which revealed that the random atomic arrangement within the electrode suppressed oxidation reaction upon contact with harsh conditions. Incorporation of amorphous metal thin film as a top electrode for organic solar cell device resulted in considerable enhancement in device stability, since the metallic surface with amorphous phase hinders ambient moisture and oxygen from permeation into underlying organic layers. The electrical parameters with the amorphous electrodes were analysed before and after aging, compared to conventional crystalline metal electrode, which revealed its advantage of maintaining high charge transport properties for extended time.
