Conductive paste composition for front electrode of solar cell and solar cell using thereof

The present invention provides a paste for a solar cell front electrode, which has a significantly low specific resistance value even in high-temperature sintering while replacing an expensive silver paste, and a solar cell front electrode including the same. The paste for a solar cell front electrode comprises a copper-silver core shell, boron and a binder. The boron forms 2.5 to 11 wt% of the total conductive paste. The conductive paste has a specific resistance value of 3.2 x 10^-5 or less in sintering of 800 °C or higher.
