Abstract
The invention relates to a positive electrode screen printing plate of a silicon solar cell. The positive electrode screen printing plate comprises a device body. A line fixing frame is arranged in the device body. The positive electrode screen printing plate is characterized in that fine grid lines are transversely distributed in the line fixing frame at intervals and main grid lines are longitudinally distributed in the line fixing frame at intervals; and sharp ends are arranged at the two ends of the main grid lines and the length of the sharp end is 15.45mm to 15.55mm. Therefore, through the matching between the fine grid line and the main grid line, positive silver printing unit consumption can be reduced to a higher extent, the light shading area of the cell is reduced, the short-circuit current of the cell is increased, the conversion efficiency of the cell is improved at last and the manufacturing cost of the cell is reduced.
