Description

Technical Field

[0001] The utility model relates to the technical field of crystalline silicon solar cells, in particular to a sub-grid plate for improving lateral transmission resistance. Background Art

[0002] like Figure 1 As shown, traditional secondary grid screens generally print grid lines in the same direction. Traditional screens improve lateral transmission resistance mainly by increasing the number of grid lines. This method requires the grid lines to be uninterrupted. Although the slurry consumption can be controlled by narrowing the grid line width, this method of narrowing the grid lines will also weaken the overall efficiency advantage.

[0003] like Figure 2 As shown, the main purpose of the anti-break grid plate is to prevent the grid line from breaking. This anti-break grid plate requires that the anti-break grid line 4 must be connected between the auxiliary grid line 2 and the auxiliary grid line 2. Although the anti-break grid line 4 has the effect of improving the lateral transmission resistance, due to its small number, its improvement effect is very limited; and if the purpose of improving the improvement effect is achieved by increasing the number of anti-break grid lines, it will lead to an increase in the consumption of slurry and increase the cost, and due to the position limitation of the anti-break grid line, it cannot play a good role in improving the lateral transmission resistance. Utility Model Content

[0004] The purpose of the utility model is to design a secondary grid plate that can improve the lateral transmission resistance, thereby solving the problem that the existing anti-breakage grid plate cannot effectively improve the lateral transmission resistance.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] The utility model designs a sub-grid plate for improving the lateral transmission resistance, and the sub-grid plate comprises:

[0007] A mesh body having transverse and longitudinal directions perpendicular to each other;

[0008] A plurality of secondary grid lines are arranged parallel to and laterally on the grid body;

[0009] Several small sub-grids are arranged on the sub-grid line perpendicularly thereto. Several small sub-grids are arranged on the same sub-grid line, and the small sub-grids pass through the sub-grid line but their two ends do not contact other sub-grid lines.

[0010] Furthermore, a sub-grid screen for improving lateral transmission resistance: the length and width of the small sub-grid can be adjusted according to the overall slurry consumption and can be set to be the same or different.

[0011] Furthermore, a sub-grid plate for improving lateral transmission resistance is provided: the spacings between a plurality of said small sub-grids on the same sub-grid line are set to be the same or different.

[0012] Furthermore, a sub-grid plate for improving lateral transmission resistance is provided: a plurality of small sub-grids are provided on each sub-grid line.

[0013] Furthermore, a sub-grid plate for improving lateral transmission resistance is provided: the small sub-grids are arranged on the spaced sub-grid lines.

[0014] Furthermore, a sub-grid plate for improving lateral transfer resistance is provided: small sub-grids on different sub-grid lines are aligned.

[0015] Furthermore, a sub-grid plate for improving lateral transfer resistance is provided: small sub-grids on different sub-grid lines are staggered.

[0016] Beneficial effects of the utility model:

[0017] (1) Compared with the conventional sub-grid plate with a denser number of grid lines, the sub-grid plate designed by the present invention for improving the lateral transmission resistance has a greater efficiency advantage under the same slurry consumption, that is, the sub-grid plate designed by the present invention can improve the efficiency by about 0.1%.

[0018] (2) The auxiliary grid plate designed by the present invention for improving the lateral transmission resistance can greatly improve the lateral transmission resistance compared with the traditional anti-break grid plate, and has low slurry consumption and low cost.
