Solar cell piece with low shading area

The invention relates to a solar cell piece with a low shading area. A plurality of parallel thin grid lines (2) and two main grid lines (3) which are perpendicular to the thin grid lines (2) are arranged on the illuminated face of the solar cell piece (1), and the solar cell piece with the low shading area is characterized in that a plurality of round holes (4) are formed in the main grid lines (3), and the thin grid lines (2) and the two main grid lines (3) are made of silver paste. The round holes are formed in the main grid lines, the use amount of the silver paste is reduced to a certain extent, the illuminated face of the solar cell piece is improved, and production cost is reduced.
