Abstract
The invention discloses a screen printing plate design method special for improving grid line shaping. A screen printing plate comprises a framework, a steel plate, a primary grid line pattern and a secondary grid line pattern, the thickness h of a steel screen is 15-20 um; the secondary grid line consists of a plurality of rectangular holes; the lengths y of the rectangular holes are 600-1,000 um, widths x are 25-50 um, and the thicknesses h1=h/2; the distances a between every two adjacent rectangular holes are 10 um; a main screen plate grid of the steel screen consists of a plurality of circular holes which are connected tightly and are 35-45 um in diameter; the distances h between every two adjacent circular holes in the same row are 3-5 um; and the distances H between every two adjacent rows of circular holes are 3-5 um. The screen printing plate design method has the beneficial effects that the grid line shaping is improved effectively, the aspect ratio of each grid line is increased by over 6 percent, and the printing quality problems of broken lines, junctions and the like are solved.
Description
Technical field
The present invention relates to crystal silicon solar batteries piece manufacture field, more particularly to it is a kind of be exclusively used in improve grid line it is moulding
Half tone method for designing.
Background technology
In crystal silicon solar batteries piece manufacturing process, serigraphy is the important procedure for producing crystal silicon solar batteries piece
One of, its printing quality directly determines the technical indicator of cell piece.In addition, silkscreen process using cost of sizing agent occupy whole
More than the 80% of individual cell piece manufacturing cost, the cost of wherein positive silver paste account for more than the 50% of whole cost.Prior art
In the design of positive electrode half tone, half tone material is silk screen and photoresists, and wherein web material has two kinds of stainless steel and nylon.This kind of material
The problems such as material easily produces broken string, node when printing in large-scale production process, and it is unfavorable for the accumulation of slurry, do not reach good
Good is moulding.Therefore, how on the premise of the photoelectric transformation efficiency of crystal silicon solar batteries piece is improved, reduce the printing of positive silver
Unit consumption and quality, reduce the purpose of production cost, become the hot issue of research in industry.
The content of the invention
The technical problem to be solved in the present invention is that offer is a kind of to be exclusively used in improving the moulding half tone method for designing of grid line, from
And further improve that grid line is moulding, reach the purpose of the problems such as solving broken string, node.
The technical solution adopted in the present invention is：It is a kind of to be exclusively used in improving the moulding half tone method for designing of grid line, including frame
Frame, steel plate, main gate line and secondary grid line figure, the thickness h of described steel plate is 15～20um；Described secondary grid line is by some rectangular
Shape hole constitute, rectangle bore hole size be length y=600～1000um, width x=25～50um, thickness h 1=h/2, phase
Adjacent two rectangle hole spacing a=10um；The main gate line of steel mesh half tone is made up of some closely coupled circular openings, its
Diameter d=35～45um, two neighboring circular hole spacing h of same row are 3～5um, and adjacent two rows circular hole spacing H is 3～5um.
The invention has the beneficial effects as follows it is moulding to effectively improve grid line, grid line depth-width ratio improves more than 6%, solve broken string,
The printing quality problem such as node.
Description of the drawings
What Fig. 1 present invention was provided is exclusively used in improving the moulding half tone design configuration of grid line
Fig. 2 is exclusively used in grid line figure in the moulding half tone of raising grid line using what the present invention was provided
In figure：X, y represent the length and width of rectangle hole respectively；A represents the spacing of two neighboring rectangle hole
The structure chart for being exclusively used in main gate line in the moulding half tone of raising grid line that Fig. 3 is provided using the present invention
In figure：D represents the diameter of each aperture；H represents the two neighboring circular hole spacing of same row；H represents adjacent two rows circle
Pitch of holes
Specific embodiment
The technical scheme of 1,2,3 pairs of present invention enforcements is described in further detail below in conjunction with the accompanying drawings.
In present embodiment, to a batch of silicon chip, using identical preparation technology, but adopting in silkscreen process
Printed with different positive electrode half tones, and its result is detected and comparative analysis.Using the special of present invention offer
In improving, the moulding half tone design parameter of grid line is as follows：The thickness h of steel mesh be 20um, carve out on steel mesh width x=30um,
The rectangle hole of length y=800um, rectangle hole spacing a=10um and thickness h 1=10um；In steel mesh half tone main gate line
It is to be engraved as circular opening, diameter d=40um, two neighboring circular hole spacing h of same row is 3um, and adjacent two rows circular hole spacing H is
3um.Parameter using conventional screen half tone is as follows：Mesh number is 360, and line footpath is 16um, and thickness is 15 ± 1um, tension force is 28 ±
1N.By 3D microscopes test result as shown in table 1, the depth-width ratio of steel mesh screen painting grid line is averagely higher by than screen mesh printing plate
8.19%, and without broken string, node problem in the slice, thin piece of printing.
Table 1 adopts steel mesh half tone and the depth-width ratio correction data after screen mesh printing plate printing
Claims (1)
1. it is a kind of to be exclusively used in improving the moulding half tone method for designing of grid line, including framework, steel plate, main gate line and secondary grid line figure,
It is characterized in that：The thickness h of described steel plate is 15～20um；Described secondary grid line is made up of some rectangle holes, rectangular
Shape bore hole size be length y=600～1000um, width x=25～50um, thickness h 1=h/2, two neighboring rectangle hole
Spacing a=10um；The main gate line of steel mesh half tone is made up of some closely coupled circular openings, its diameter d=35～45um,
Two neighboring circular hole spacing h of same row is 3～5um, and adjacent two rows circular hole spacing H is 3～5um.
