Tri-gate electrode of solar cell

The utility model discloses a tri-gate electrode of a solar cell, which comprises a back electrode (1) and a positive electrode (2), wherein the back electrode (1) and the positive electrode (2) are arranged on a cell panel, the back electrode (1) is divided into discontinuous segments, and three main gate lines (3) of the positive electrode (2) are divided into discontinuous segments. Compared with the conventional battery, the tri-gate electrode of the solar cell has the advantages that the electrode coverage area is greatly reduced, both of the coverage areas of the back electrode and the positive electrode are reduced, silver paste consumption is correspondingly reduced, the unit consumption of silver paste is greatly reduced, and the production cost is saved.
