Abstract
It the utility model is related to a kind of anti-offset structure of solar cell substep printed pattern, including main gate line and secondary grid line, main gate line both sides integrated molding has the projection for being connected with the secondary grid line, wherein positioned at cell piece surface, the adjacent two secondary grid lines of outermost are continuous secondary grid line up and down, and adjacent two continuous secondary grid lines, by aiding in secondary grid line to connect, the relatively continuous secondary grid line of the secondary grid line of auxiliary is vertical；The secondary grid line of auxiliary is covered in main gate line；Secondary grid line between continuous secondary grid line up and down is the secondary grid line of interruption.The utility model substep can be prevented in printing because main gate line vertical misalignment and caused by projection position and the secondary grid line of main gate line disconnect, while the anti-offset structure that the solar cell substep for being easy to detect main gate line lateral shift prints electrode.
Description
Technical field
Manufacture of solar cells manufacturing field is the utility model is related to, specifically discloses a kind of solar cell substep printing figure
The anti-offset structure of shape.
Background technology
With the continuous ripe and progress of crystal silicon solar energy battery technology, cost control is increasingly becoming battery process optimization
And new technology development first has to the problem of consideration.
Front side silver paste occupies very big proportion in crystal silicon solar batteries manufacturing cost, accounts for the 60%~70% of non-silicon cost
Between.The difference required according to main gate line and thin grid line pulp property, by main grid and secondary grid split design two pieces of half tones it
It is upper to use distribution typography, substantially reduce and be manufactured into using different silver pastes and reduction silver paste unit consumption from secondary grid by main grid
This.
But distribution typography design half tone is used three to be present：
1st, because the parallel lines that secondary grid line is a plurality of main grid position fixed width interruption, main gate line vertically pass through each bar pair grid
Line, if vertical misalignment (i.e. perpendicular to the skew in secondary grid line direction) occurs for main gate line in printing process, the prominent of main gate line will be caused
Position is played with being interrupted the secondary all off connection of grid line, directly affects electric current collection.
If the 2, lateral shift (i.e. parallel to the skew in secondary grid line direction) occurs for main gate line in printing process, main grid will be caused
The projection position of line side disconnects influence electric current collection with secondary grid line, and skew during test below due to main gate line causes
Test probe is not fully pressed against on main grid, and then cause to test electrical performance data exception.
If the 3, main gate line rotates skew (i.e. main gate line direction and secondary grid line direction out of plumb) in printing process, will lead
Main gate line part projection position is caused to disconnect influence electric current collection with secondary grid line.
Utility model content
Goal of the invention of the present utility model is：Being there is provided for solution problem above during a kind of substep prints can prevent because of master
Grid line vertical misalignment and caused by projection position and the secondary grid line of main gate line disconnect, while be easy to carry out main gate line lateral shift
The anti-offset structure that the solar cell substep of detection prints electrode.
The technical solution adopted in the utility model is such：
A kind of anti-offset structure of solar cell substep printed pattern, including main gate line and secondary grid line, main gate line both sides
Integrated molding has the projection for being connected with the secondary grid line, wherein adjacent two pairs of outermost above and below cell piece surface
Grid line is continuous secondary grid line, and adjacent two continuous secondary grid lines, by aiding in secondary grid line to connect, the secondary grid line of auxiliary is relative to be connected
It is vertical to continue secondary grid line；The secondary grid line of auxiliary is covered in main gate line；Secondary grid line between continuous secondary grid line up and down is interruption
Secondary grid line.
Further, the continuous secondary grid line is located on the center line of each width in main gate line share.
In summary, due to being using above-mentioned technical proposal, the beneficial effects of the utility model：
1st, the present invention by the adjacent two secondary grid lines of outermost up and down of corresponding main gate line printing zone in secondary aperture plate version it
Between with aiding in secondary grid line to be connected into " mouth " font, can observe directly whether main gate line occurs with reference to the position naked eyes of secondary grid line are aided in
Vertical misalignment or rotation offset, only do not determine that major and minor grid line connection can in the case of off normal in upper and lower " mouth " character form structure
Lean on, ensure that battery performance；
2nd, two vertical with the secondary grid line secondary grid lines of auxiliary can be as the positioning datum of main gate line, when horizontal stroke occurs for main gate line
To during skew, optical microscope measuring can be utilized to aid in the relative position of secondary grid line and main gate line, accordingly can be with accurate judgement
The direction of main grid skew and distance simultaneously make amendment in time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of anti-offset structure of solar cell substep printed pattern, including main gate line 1 and secondary grid line
2, the both sides integrated molding of main gate line 1 has that multiple (main grid cable architecture is in centipede for the projection 11 that is connected with the secondary grid line 2
Shape), wherein above and below cell piece surface the adjacent two secondary grid lines 2 of outermost for continuous secondary grid line 21 (top is adjacent two, under
Fang Xianglin two, totally 4 continuous secondary grid lines 21), and adjacent two continuous secondary grid lines 21 are by aiding in secondary grid line 3 to connect；It is described
Aid in the relatively continuous secondary grid line 21 of secondary grid line 3 vertical, and it is located on the center line of each width in the share of main gate line 1, that is, exists
Formed with square openwork part in main gate line 1, aid in secondary grid line 3 to be located in openwork part left and right sides, aid in secondary grid line 3 to distinguish position
In on the segment centerline；Secondary grid line 2 between continuous secondary grid line 21 up and down is the secondary grid line 22 of interruption.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
