Metallic glass (MG) can be a promising additive for the screen-printed silver electrode, when the composition of MG is properly tailored. When Cu-Zr-Al MG is used as an additive, the contact resistance between the Ag electrode and the Si emitter significantly decreases down to 5.39 mΩ cm 2 on 100 Ω/sq of emitter, while when Cu-Zr Mg is used, the contact resistance is 31.28 mΩ cm 2. Wider supercooled-liquid region and high reactivity with silver of Cu-Zr-Al MG lead to wider contact area of the Ag electrode and higher density of Ag crystallites, resulting in such a low contact resistance.
