摘要
The present invention relates to a silver coated glass frit used in a paste composition for forming a solar cell electrode, a method for preparing the same, and a silver paste composition using a silver coated glass frit for a solar cell. More specifically, the present invention relates to: a method for preparing a silver-coated glass frit wherein a silver coated glass frit, in which silver (Ag) is coated on a surface of the glass frit, is prepared through a reduction reaction occurring by adding, to a first solution containing silver nitrate (AgNO3) mixed with a glass frit and an amine, a second solution containing a reductant, and during the preparation process, a silver (Ag) coating layer is more uniformly formed on the surface of the glass frit by controlling the acidity of the first solution and the reaction temperature in the reduction reaction, thereby achieving an improved specific surface area; a silver-coated glass frit prepared by the method; and a silver paste composition for a solar cell wherein the composition is prepared by using the sliver-coated glass frit, and thus has significantly improved sintering characteristics and electrical conductivity.
