Abstract
The utility model relates to a novel polycrystalline silicon solar battery grid line structure. Thin grid lines which are vertical to the direction of a front-surface electrode are densely distributed on the front surface of a battery sheet, the thin grid lines which are parallel to the direction of the front-surface electrode are arranged at the two ends of the thin grid lines which are vertical to the direction of the electrode, and the thin grid lines which are parallel to the direction of the front-surface electrode are used for two-two connection of the thin grid lines vertical to the direction of the front-surface electrode. The novel polycrystalline silicon solar battery grid line structure can enhance the capability of collecting current by the thin grid lines of the battery sheet, reduce the light-blocking area of the thin grid lines, be conductive to upgrading the performances of the solar battery sheet, reduce the consumption of silver paste for screen printing and be conductive to reducing production cost.
