The method for forming a front electrode of a solar cell according to the present invention relates to a process whereby a front electrode is formed on the surface of a semiconductor layer of a solar cell. The method for forming a front electrode on the front surface of the semiconductor layer of a solar cell, comprises the steps of: printing an electrode solution on the front surface of the semiconductor layer for forming the electrode; and hardening said electrode solution such that said electrode solution printed on said semiconductor layer by said electrode-forming step configures said front electrode. Said electrode solution is formed by mixing a bonding agent for bonding said semiconductor layer and said metal, and the metal for forming said front electrode. Said electrode-forming step provides an electric charge to said electrode solution by means of the electric energy applied by one or more electrohydrodynamic (EHD) inkjet printing operations, and discharges said electrically-charged electrode solution from a nozzle by means of an electrostatic force. |
