Document Type and Number:
WIPO Patent Application WO/2020/118781
Kind Code:
A1
Abstract:
A glass powder composition, a conductive silver paste containing glass powder composition, and a solar cell. The glass powder composition is a Te-Pb-Ta-based glass powder composition. According to the weight of a corresponding oxide, components of the glass powder composition comprise: Te(5-95):Pb(5-50):Ta(1-20). The conductive silver paste contains the glass powder composition, and the solar cell using the conductive silver paste has good corrosion capability for silicon nitride, aluminum oxide, and a silicon oxide passivation layer, and has good wetting capability for silver and silicon bases.
