Chinese patent CN202058761U discloses the positive silver-colored half tone of a kind of screen printing crystalline silicon solar cell; Comprise: silicon chip, main grid line, chamfering, secondary grid line, described silicon chip are provided with main grid line and secondary grid line, and described main grid line is provided with secondary grid line is vertical, on described silicon chip, is provided with chamfering; Can the front electrode grid line effectively be expanded at silicon chip surface; Increase area coverage, photoelectric current is carried out effective collection, thereby improved the efficient of battery sheet.
Chinese patent CN101969082A discloses the solar cell fabrication process that a kind of twice serigraphy combines with cutting; Be used to make a kind of solar cell that prints electrode for twice; Include cutting technology and twice typography; Cutting technology is: in the gate electrode line zone cutting of silicon chip surface, make the gate electrode line zone form the erosion groove; Twice typography is: a, first impression electrode: the electrode slurry of printing is inserted the erosion groove and dried formation ground floor electrode in the erosion groove; B, second impression electrode: print electrode at ground floor electrode outer surface, make silicon chip surface gate electrode line zone form second layer electrode.
Adopt traditional battery electrode Printing screen to print, mainly have following problem: the oven wire mesh blanket that 1, constitutes printing screen plate is a Weaving type, has the longitude and latitude node of Weaving type on it, is unfavorable for realizing the uniformity of printing; 2, to pass through the slurry amount few for one-step print, occurs empty seal easily, i.e. breakpoint, and the depth-width ratio of thin grid line is little; Though 3, repeatedly printing can be avoided empty seal, thin grid line seriously broadens, and influences the battery illuminating area; And the result who repeatedly repeats print is thin grid line out-of-flatness; " camel " peak appears, this kind repeatedly mode of printing not only cost is high, and do not bring corresponding benefit; Be not suitable for the production of scope of the enterprise property, be badly in need of Printing screen rational in infrastructure in the industry.
In order to overcome the deficiency of prior art, the object of the present invention is to provide a kind of woven wire, its web plate for electrode of solar battery printing usefulness is made a kind of substrate is provided.
Summary of the invention
One of technical problem to be solved by this invention is that solar cell adopts traditional battery electrode Printing screen to print in the prior art, and empty seal appears in one-step print easily; Repeatedly the uniformity of printing is low-cost high, is not suitable for the problem of scope of the enterprise property production, and the present invention provides a kind of new woven wire, and it is low that this silk screen has a uniformity height, no breakpoint, cost, the advantage of suitable large-scale production.
Two of technical problem to be solved by this invention provides a kind of solar base plate that adopts above-mentioned woven wire to process, and this substrate has the simple advantage of preparation.
For one of solving the problems of the technologies described above; The technical scheme that the present invention adopts is following: a kind of woven wire; Comprise grid regions, non-grid regions; Said grid regions links to each other with non-grid regions, and said grid regions is made up of two groups of orthogonal grid lines groups, and the grid regions zone line of said woven wire is provided with the graphics field; The grid lines line footpath that constitutes said woven wire graphics field is even, and said figure is made up of the grid lines of disappearance; Said non-grid regions is arranged on the periphery of grid regions, is provided with lateral opening array in the periphery of non-grid regions.
In the technique scheme, said grid regions is made up of two groups of orthogonal grid lines groups.The grid lines line footpath that constitutes said woven wire graphics field is even, and said figure is made up of the grid lines of disappearance.Figure and its purposes that said disappearance grid lines constitutes adapt.The grid lines line footpath of the relative zone line of edge grid lines of said grid regions is big, and it constitutes the buffering area that grid regions is connected with non-grid regions.The grid lines line footpath of said buffering area evenly or with certain rules is increased toward edge direction by middle gradually.Said non-grid regions is arranged on the periphery of grid regions, and is equipped with lateral opening array in the outer periphery of non-grid regions.Said woven wire material is pure nickel, dilval, nickel-base alloy and other various suitable metal materials, and it forms through the electroforming process preparation.
For solve the problems of the technologies described above two, the technical scheme that the present invention adopts is following: a kind of solar base plate that adopts above-mentioned woven wire to process.
In the technique scheme, the figure that the said disappearance grid lines of woven wire constitutes is one group of lines that are parallel to each other, and its thin grid line with the electrode of solar battery Printing screen is corresponding.
Woven wire provided by the invention; It has the following advantages: 1, said woven wire is to make through electroforming process; It has the characteristic of surfacing, no Weaving type longitude and latitude node, starches at present evenly in printing through the electrode of solar battery Printing screen of its making; 2, said woven wire does not have the grid lines on the direction of thin grid line place in the corresponding zone of the thin grid line of corresponding solar cell electrode Printing screen, has reduced the inhibition of woven wire to the printing slurry.
