Abstract
The utility model discloses a kind of solar energy steel plate half tone that can eliminate edge grid line distortion, comprise the steel plate half tone that photovoltaic is used, and the redundancy grid line of the release tension force arranging in both sides, half tone graphics field.The steel plate half tone that described photovoltaic is used refers to the steel plate half tone processing by any modes such as electroformed nickel alloy sheet, laser cutting stainless steel substrates or chemically etched metal sheets, the grid line aperture opening ratio of described steel plate half tone can not be from 40% to 100% not etc., the beneficial effects of the utility model are: due to the characteristic of steel plate half tone, the tension force of its screen cloth when stretching tight net can be applied to graphics field, edge grid line in graphics field is deformed, even directly explosion, causes product failure.And after outside, graphics field has added the redundancy grid line of the utility model design, tension force can be discharged on redundancy grid line, so both guaranteed the success rate that half tone is made, guaranteed again the stability of graphics field.
Description
Technical field
The utility model relates to manufacture of solar cells technical field, particularly a kind of solar energy steel plate half tone that can eliminate edge grid line distortion.
Background technology
Metallization is the committed step of manufacturing solar cell.So-called metallization, generally refers to and adopts method for printing screen to make solar cel electrode.Specifically, be that the electrode pattern of expectation is turned to shadow on screen mesh printing plate or small opening half tone, the electrode of the solar cell that on half tone, the corresponding expectation in the region of perforate obtains; Again the metal paste with certain fluidity is coated on half tone; Then utilize scraper to apply certain pressure to half tone and metal paste, and the half tone surface of fitting moves to the other end from a section of half tone, under the extruding of scraper, metal paste, by seeing through the opening area of half tone, is transferred on solar cell; Finally, the solar cell that prints metal paste is placed in to high temperature and carries out sintering, the metal ingredient in metal paste is effectively contacted with solar cell, just completed whole metallization processes.The live width of the quality of metallization quality, particularly printed pattern and uniformity thereof, very big on the impact of the outward appearance of solar cell and performance.Printed pattern live width is less, and efficiency of solar cell is higher; Printed pattern live width is more even, and the outward appearance of solar cell is better.
In order to reduce photovoltaic generation cost, the transformation efficiency that reduces solar cell manufacturing cost or raising solar cell is two effective ways.Along with the continuous progress of industrial production technology, solar cell manufacturing cost is in continuous decline, and battery efficiency is also improving constantly.In the situation that battery structure does not change, typography has remarkable impact to battery efficiency, and wherein the optimization of front gate line figure can obviously promote battery efficiency.Therefore, in recent years, positive aperture plate version design live width is more and more thinner, and conventional half tone live width is little of ~ 45 microns.But due to the restriction of conventional half tone silk screen string diameter, design live width has reached the limit substantially, thinner grid line design can cause printing the raising of fraction defective.
In recent years, electroforming half tone starts the application at photovoltaic industry gradually.Electroforming half tone has the percent opening that is greater than 70%, grid line width design can be low to moderate <30um, printing live width can be low to moderate <50um, the application of this type of half tone can reduce the shading-area of front metal grid line greatly, brings the improved efficiency of >0.2%.
At present, the ratio of this type of half tone application is also very little, and one of reason is the more strict control of typography needs for this kind of half tone, and inappropriate printing parameter control can bring the bad generation of printing.The modal printing of this type of half tone is bad shows as two, edge grid line wider width, the figure of design width ~ 30um, and edge grid line width even can reach 500um.This phenomenon is closely-related with the feature of this type of half tone, because this type of half tone grid line percent opening is greater than 70%, therefore, can cause that with the tension force of grid line vertical direction half tone is out of shape longitudinally, causes edge grid line printing partially thick.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of solar energy steel plate half tone that can eliminate edge grid line distortion, solves the problem of the edge grid line chap of steel plate half tone.。
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of solar energy steel plate half tone that can eliminate edge grid line distortion, comprise expanded metal lath edition owner body, described expanded metal lath edition owner body is comprised of screen frame, peripheral silk screen screen cloth and metal film, on described metal film, be provided with graphics field, in described graphics field, be provided with edge grid line, outside half tone graphics field in expanded metal lath edition owner body, redundancy grid line is set, the position of described redundancy grid line is arranged on metal film, between peripheral silk screen screen cloth and graphics field.
As further improvement of the utility model, the shape of described redundancy grid line can be that number is more than or equal to the grid line of, the length dimension of grid line is 0cm-30cm, and the width dimensions of grid line is 10um-80um, and grid line can exist number to be more than or equal to one breakpoint.
As further improvement of the utility model, the aperture opening ratio of described redundancy grid line can be 0%-100%.
As further improvement of the utility model, described screen frame material is aluminium or cast iron.
As further improvement of the utility model, described peripheral silk screen screen cloth is nylon mesh or polyester screen cloth.
As further improvement of the utility model, described metal film is by laser cutting, the sheet metal that the methods such as electroforming or chemical attack make.
As further improvement of the utility model, described edge grid line aperture opening ratio is 50%-100%.
The beneficial effects of the utility model are: the utility model is owing to being provided with redundancy grid line outside half tone graphics field, make when making half tone, can on the redundancy grid line in outside, graphics field, be discharged with the tension force of grid line vertical direction, be that certain distortion can occur redundancy grid line, but the grid line in graphics field will be not can redeformation, the pattern printing just can not be out of shape yet, and so, has solved the distortion of expanded metal lath domain shape edges of regions grid line and has caused edge grid line to print thick problem.
