METALLIC PASTE COMPOSITION FOR FORMATION OF AN ELECTRODE, AND AG-C COMPOSITE ELECTRODES AND SILICON SOLAR CELLS USING THE SAME

摘要

The present invention relates to a metallic paste composition for formation of an electrode, and Ag-C composite electrodes and silicon solar cells using the same.  The metallic paste composition for forming electrodes, comprises glass frit powder, silver powder and an organic binder further comprising a carbon-based material powder, wherein the carbon-based material is contained in an amount of not greater than 20 wt%, preferably not greater than 25 wt%, with respect to 100 wt% of the silver powder, and optionally, silver particles in the silver powder have an average particle diameter of not greater than 1 mm.  Despite the relatively low silver content in the inventive metallic paste composition for formation of an electrode, electrical properties of the thus produced electrodes are not substantially degraded.
