METAL PASTE COMPOSITION FOR FORMING ELECTRODE AND SILVER-CARBON COMPOSITE ELECTRODE AND SILICON SOLAR CELL USING THE SAME

摘要

Provided are a metal paste composition for forming an electrode, and a silver-carbon composite electrode and a silicon solar cell using the same. The metal paste composition for forming an electrode including glass frit powder, silver powder and an organic binder further includes 20 or less parts by weight, preferably 25 or less parts by weight of carbon-based material powder based on 100 parts by weight of the silver powder. Optionally, the silver powder has an average particle size of 1 μm or less. An electrode formed using the metal paste composition does not have a substantial deterioration in its electrical characteristics although the silver content is reduced.
