Abstract
The invention relates to a method for welding a crystalline silicon solar cell piece. The method is characterized in that a welding operator vertically places a welding strip and a solar cell piece to be welded in the front along a main grid line; the lower end of the welding strip is 3-8 mm away from the lower rim of the solar cell piece; the welding strip is kept thoroughly covering the main grid line to be welded; an electric welding iron begins the welding at a position of the welding strip, which is 3-8 mm away from the upper rim of the solar cell piece; and the electric welding iron moves downwards along the welding strip to reach a blank area at the lower end of the welding strip, which is 3-8 mm away from the lower rim of the solar cell piece. The method achieves the placement by means of 180-degree rotation based on the original welding placement, thereby preventing welding tin from accumulating on an upper electrode welding strip of a solar cell, retaining surplus welding tin on the main grid line of the cell piece in the blank area between a terminal of the upper electrode welding strip and the rim of the cell piece, extending the welding strip and reducing the stress brought by the welding tin accumulation to the cell piece.
Description
Technical field
The present invention relates to a kind of on the crystal-silicon solar cell top electrode new method of manual welding welding.
Background technology
Make at present solar module, at first need interconnectedly, therefore need on the solar cell top electrode, weld welding, and then the welding of welding is welded on the bottom electrode of another solar cell piece solar cell.Manual welding top electrode welding has two kinds of methods at present: transverse weld method and vertical welding side, but based on vertical welding.
So-called transverse weld method is exactly welding and solar cell along main grid line direction is laterally to place in face of welding personnel, and the electric iron of welding is laterally to move in welding process.Because the stability of the restive welding of transverse weld method is eliminated by vertical welding method gradually.
Vertically welding method be exactly welding and solar cell be vertically to place in face of welding personnel along main grid line direction, and the electric iron of welding vertically moves in welding process.But as shown in Figure 3, the starting point of present vertical welding method regulation welding is positioned at the C point that welding is placed on the solar cell upper end, moves down the D point end of electric iron to the solar cell lower end then, and welding is welded on the top electrode main grid line of solar cell.Such welding method, when electric iron moved down, the scolding tin of fusing can move down along with the mobile of electric iron, and it is exactly on the welding at solar cell edge that final unnecessary scolding tin can be deposited in B point electricity.The accumulation of scolding tin, this that makes the battery sheet bears bigger stress always in the subsequent production process of assembly, be easy to cause battery sheet crackle.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned the deficiencies in the prior art, provides a kind of and reduces because scolding tin is piled up the method to the welding crystalline silicon solar cell piece of battery stress that sheet forms.
The technical solution used in the present invention is as follows:
A kind of method of welding crystalline silicon solar cell piece, it is characterized in that: in face of welding personnel vertically is placed on welding and soldered battery sheet along the main grid line, the lower end of welding is apart from battery sheet lower limb 3-8mm and keep welding to cover the main grid line of required welding fully, the welding electric iron begins welding from welding apart from 3-8mm position, battery sheet top edge below, electric iron moves down and moves to always the white space of 3-8mm between welding lower end and the battery sheet lower limb along welding, and will draw on the main grid line of falling 3-8mm white space between welding lower end and the battery sheet lower limb with the unnecessary scolding tin that electric iron moves.
Beneficial effect of the present invention has:
The present invention has rotated 180 degree with original welding disposing way and has placed, avoided the accumulation of scolding tin on the top electrode welding of solar cell, again unnecessary scolding tin is retained on the main grid line of the battery sheet between the clear area between top electrode welding terminal and the battery sheet edge, played the effect of extending welding, reduced because scolding tin is piled up the formed stress of battery sheet.
Description of drawings
The position view of welding when Fig. 1 welds the battery sheet for the present invention.
Fig. 2 is the position view of battery sheet welding back welding.
The position view of welding when Fig. 3 welds the battery sheet for having now.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As Figure 1-3, in face of welding personnel vertically is placed on soldered battery sheet 1, left hand (when the right hand welds) thumb, forefinger and middle finger promote welding 2 and navigate on the main grid line 3 that battery sheet 1 will weld, and make the lower end of welding 2 be positioned at approximately 3-8mm distance and position place, battery sheet 1 lower limb top.The right hand is held electric iron, begin to weld from the A point of welding 2 near the about 3-8mm of battery sheet 1 top edge, electric iron moves down and keeps welding 2 to cover the main grid line 3 that is welded fully along welding, move to the lower end of welding 2 when electric iron after, need be moved down into the B point again, to draw on the main grid line 3 of falling 3-8mm white space between welding 2 lower ends and battery sheet 1 lower limb with the unnecessary scolding tin that electric iron moves, finally obtain welding effect shown in Figure 2.
Other undeclared part of the present invention is identical with present technology.
