Abstract

In this study, electrically conductive Al-based metallic glass (MG) has been applied as an alternative of oxide glass in silver paste. Al85Ni5Y8Co2 MG powder was produced by gas atomization process and simultaneously classified depending on the size of powder. The wetting behavior of MG was dramatically altered by the degree of crystallinity and the size of MG powder, resulting in the different sinterability of silver (Ag) and contact area between Si emitter and Ag. The Ag electrode with smaller MG powder shows much denser structure of Ag and larger contact area, leading to low contact resistance, 0.69 ± 0.38 at p-type and 0.56 ± 0.13 mΩcm2 at n-type emitter.
