[0009] In the N-type TOPCon cell, aluminum paste and a small amount of silver paste are respectively used on a front side of the substrate, so as to prepare aluminum fine grids and segmented silver main grids. The aluminum fine grids gather collected currents to the silver main grids, and the silver main grids meet a soldering requirement. The
Aluminum-added silver paste (silver/aluminum paste) has been used as metallization for p + emitter of n-type solar cells, because the addition of aluminum powder to the silver paste can effectively decrease contact resistance between the paste metallization and the p + emitter.
The Ag–Al paste was prepared by a pre-mix step of glass frit and organic carrier followed by a complete mix step carried out in a three-roll mill with the addition of Ag and Al powder. In the Ag–Al paste, the weight ratio of organic carrier and inorganic solid powder was controlled at 10:90.
Specifically, Al is added to the Ag conductive paste to increase the contact points. The contact resistivity may be reduced about three orders of magnitude, because the silver/aluminum paste creates large and deep metal spikes [26, 27].
The as-prepared paste was screen-printed on n-type monocrystalline Si wafers (15.6 cm × 15.6 cm) with a resistivity of 1–3 Ω cm. The Si wafers were then baked and sintered in an industrial tunnel furnace with a peak temperature of 750°C. The electrical properties of the sintered wafers were evaluated by multiple methods.
Compared with Ag paste, Ag–Al paste provides a considerably lower contact resistance with the p+ emitter. Electrical tests revealed a smaller Ag/Si contact resistance and higher Ag electrode resistance with increasing Al concentrations in the Ag–Al paste.
