GLASS PHASE FORMING AGENT, METAL INK COMPOSITION WITH THE SAME FOR FRONT ELECTRODE OF SILICON SOLAR CELL, AND SILICON SOLAR CELL USING THE SAME

摘要

PURPOSE: A metallic ink comprising a glass phase forming agent is provided to simplify the manufacturing process of a solar cell by forming a front electrode using one non-contact type printing, to increase producing yield comparison to an existing screen printing method, and to embodying micro metal circuit. CONSTITUTION: A glass phase forming agent comprises a metal compound for forming glass phase, and an organic solvent capable of melting the metal compound. The metal compound is one or more compounds selected from metal nitrate, metal acetate, and hydrate thereof. A metallic ink compound comprises the glass phase forming agent, and a metal nanoparticles or the metal compound. A silicon solar cell comprises a front electrode formed by printing the metallic ink compound comprising the glass phase forming agent. The organic solvent is selected from the group consisting of alcohols, polyhydric alcohols, ethers and glycol ethers.
