The invention provides a solar cell grid line structure, a solar cell sheet and a solar lamination module. The grid line structure comprises a plurality of sub grid lines arranged on a silicon wafer and a main grid line perpendicular to the sub grid lines. The main grid line is formed by a grid-like porous structure. When the main grid line is coated with a conductive paste, grid holes are filledwith a part of the conductive paste.
