METHOD FOR SOLAR CELL METALLIZATION USING CONDUCTIVE INK WITH NANO SIZED GLASS FRIT BY SOL-GEL PROCESS

摘要

PURPOSE: A manufacturing method of a nano-sized glass frit is provided to obtain high producibility in low costs by using a solution method, and to easily control the size and composition for a solar cell electrode. CONSTITUTION: A manufacturing method of a nano-sized glass frit comprises: a step of manufacturing glass frit nanoparticles by using a sol-gel synthesis method; and a step of mixing the glass frit nanoparticles, metallic nanoparticles, and organic vehicles. An electrode for a solar cell comprises a semiconductor substrate, an antireflection film formed on the substrate, a first conductive layer which is formed by spreading the conductive ink on the antireflective film, and a second conductive film formed of a conductive metal, on the first conductive layer.
