Abstract
This utility model relates to filed of crystal silicon solaode technique, particularly relate to a kind of screen cloth structure for printing crystal-silicon solar cell front electrode, including screen cloth body (1), it is arranged on screen cloth body (1) and is provided with for the first vacancy section of the secondary grid line of printing first and for the second vacancy section of the secondary grid line of printing second, described first vacancy section includes a plurality of the first hollow out bar (2) be arrangeding in parallel, described second vacancy section includes a plurality of second hollow out bar (3) vertical with the first hollow out bar, the ratio of the width of described second hollow out bar (3) and the width of the first hollow out bar (2) is 0.65 0.85.Use the first secondary grid line that this screen cloth structure can make to print roughly the same with the second pair grid line width.
Description
Technical field
This utility model relates to filed of crystal silicon solaode technique, particularly relates to a kind of for printing crystalline silicon sun electricity
The screen cloth structure of pond front electrode.
Background technology
The electrode of crystal-silicon solar cell makes generally by the mode of silk screen printing.Detailed process is: first make
The template of electrode shape, the namely screen cloth on half tone, be then layered on electrode slurry on the screen cloth making electrode pattern, profit
Extruding screen cloth with scraping article, along with the movement of scraping article, slurry will be bitten on cell piece from area of the pattern, forms electrode.
Crystal-silicon solar cell front electrode includes main gate line and secondary grid line.The effect of main gate line is primarily to assembly welds
Connecing, secondary grid line effect is to collect photo-generated carrier, and in order to strengthen electric current collection effect, improves cell photoelectric conversion effect
Rate, secondary grid line includes the secondary grid line of first vertical with main gate line and the parallel with main gate line second secondary grid line, so on screen cloth
It is also required to be provided for print the first vacancy section of the first secondary grid line and for the second vacancy section of the secondary grid line of printing second.?
In prior art, the first vacancy section on screen cloth is identical with the width of the second vacancy section, and print direction is and the first vacancy section
Consistent, so when printing, when scraping article is printed onto second vacancy section parallel with scraping article, the power on scraping article can all act on
On the second vacancy section, the most easily slurry is extruded more, cause the be printed on cell piece second secondary grid line than design
Want thick, and then cause battery shading-area to become big, efficiency step-down, and also slurry can be wasted, simultaneously consistent to battery outward appearance
Property also creates certain impact.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of the first secondary grid line and second that can make to print
The screen cloth structure for printing crystal-silicon solar cell front electrode that secondary grid line width is roughly the same.
This utility model be the technical scheme is that a kind of screen cloth for printing crystal-silicon solar cell front electrode
Structure, including screen cloth body, be arranged on screen cloth body be provided with for the first vacancy section of the secondary grid line of printing first and for
Second vacancy section of the secondary grid line of printing second, described first vacancy section includes a plurality of the first hollow out bar be arrangeding in parallel, described the
Two vacancy sections include a plurality of second hollow out bar vertical with the first hollow out bar, it is characterised in that: the width of described second hollow out bar
It is 0.65-0.85 with the ratio of the width of the first hollow out bar.
Using above structure compared with prior art, this utility model has the advantage that and prints by being used on screen cloth
What what the second hollow out bar of second mate's grid line did did is narrower, so because having slurry to extrude during printing the second secondary grid line, and institute
It is roughly the same with the width of the after being completed for printing first secondary grid line and the second secondary grid line, is i.e. not result in the shading surface of cell piece
Long-pending change is big, improves battery efficiency, and decreases the waste of slurry, and can guarantee that the concordance of battery outward appearance.
As preferably, the ratio of the width of described second hollow out bar and the width of the first hollow out bar is 0.7-0.8.So arrange
After making to print, both stand outs are away from less.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model screen cloth.
As shown in the figure: 1, screen cloth body；2, the first hollow out bar；3, the second hollow out bar.
Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with accompanying drawing, but this utility model is not only
It is limited to detailed description below.
A kind of screen cloth structure for printing crystal-silicon solar cell front electrode, including screen cloth body 1, is arranged on screen cloth
Body 1 is provided with for the first vacancy section of the secondary grid line of printing first and for the second vacancy section of the secondary grid line of printing second,
Described first vacancy section includes a plurality of the first hollow out bar 2 be arrangeding in parallel, and described second vacancy section includes a plurality of and the first hollow out
The second hollow out bar 3 that bar is vertical, the ratio of the width of described second hollow out bar 3 and the width of the first hollow out bar 2 is 0.65-0.85.
The ratio of the width of described second hollow out bar 3 and the width of the first hollow out bar 2 is 0.7-0.8.
The surrounding of described first hollow out bar 2 and the second hollow out bar 3 is additionally provided with a grade bar.
The width design of the first hollow out bar 2 can be become 0.036mm in this specific embodiment, then the second hollow out bar 3 designs
Become 0.029mm.So print direction is with the direction of the first hollow out bar is consistent.
Claims (2)
1., for printing a screen cloth structure for crystal-silicon solar cell front electrode, including screen cloth body (1), it is arranged on screen cloth
Body (1) is provided with the first vacancy section for the secondary grid line of printing first and the second hollow out for the secondary grid line of printing second
District, described first vacancy section includes a plurality of the first hollow out bar (2) be arrangeding in parallel, and described second vacancy section includes a plurality of with first
