Silver coated glass frit, method for preparing same, and silver paste compoisition using silver coated glass frit for solar cell
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.

Lithium-Tellurium Silicon-Lead Bismuth Multi-component Glass-Oxide-Complex System and Conductive Paste Containing Same
The present disclosure discloses a lithium-tellurium silicon-lead bismuth multi-component glass-oxide-complex system and conductive paste containing same, belonging to the technical field of solar cells. According to the present disclosure, a “functional modularization” strategy is adopted in a formula design of the glass-oxide-complex system, and glass oxide systems with selective reactivity for different passivation layers are compounded based on the structures, compositions and thicknesses of the passivation layers, so that a paste formula is developed, which is composed of lithium-containing, tellurium-silicon-containing and lead-containing glass oxides. Due to adoption of the modularized formula strategy, active ingredients can be better controlled, and the overall paste formula is more optimized, so that the laminated passivation layers can be selectively burned through to obtain a more balanced contact, and better battery performance on silicon wafers with different passivation layer thicknesses can be achieved, thus achieving excellent photoelectric conversion efficiency.
