Abstract
The invention provides a method for manufacturing an anode screen plate for improving the solar cell silicon sheet conversion rate. The method comprises the following steps: 1, superposing and contrasting an anode printing figure and a screen plate figure by computer software; 2, adjusting the spacing between adjacent longitude wires on the fine grid wire part of the anode printing figure of a corresponding solar cell silicon sheet; 3, increasing the wire diameters of the longitude wires and latitude wires of the anode screen plate outside of the anode printing figure of the solar cell silicon sheet; and 4, completing the manufacturing of the screen plate through in an electroforming or micro-cutting manner according to the figure. The method solves a problem that the conversion rate of the solar cell silicon sheet cannot breakthrough because the printing of screen plates in the prior art is discontinuous and nonuniform, and the spacing between the adjacent longitude wires of the screen plate is adjusted to make the fine grid wire of the anode printing figure have no network nod blocks. The screen plate manufactured through adopting the method has the advantages of no discontinuity after the silver slurry printing, uniform printing, fine grid wire width, and improvement of the cell sheet conversion rate.

In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is:
The positive electrode silk screen plate manufacturing approach that a kind of solar silicon cell conversion ratio is high comprises the steps:
(1) the solar silicon cell positive electrode printed pattern and the standard silk screen plate figure that the client are provided are input to the contrast that superposes in the correspondent computer software;
(2) according to the analysis of computer software, the spacing of the adjacent warp at the thin grid line of the corresponding solar silicon cell positive electrode printed pattern place of adjusting silk screen plate makes its 2-3 that increases to primary leading doubly;
(3) the line footpath of the warp of the positive electrode silk screen plate outside the adjustment solar silicon cell positive electrode printed pattern, parallel is to original 1.5-2 times;
(4) the adjusted positive electrode silk screen plate figure of output from computer software adopts the mode of electroforming or little cutting to accomplish the manufacturing of silk screen plate according to the figure of exporting.
The positive electrode silk screen plate manufacturing approach that aforesaid a kind of solar silicon cell conversion ratio is high is characterized in that: standard silk screen plate figure is with the mode and the solar silicon cell positive electrode printed pattern stack contrast of zero inclination in the step (1).
The positive electrode silk screen plate manufacturing approach that aforesaid a kind of solar silicon cell conversion ratio is high is characterized in that: the warp of the positive electrode silk screen plate in the solar silicon cell positive electrode printed pattern, the line of parallel directly are 10-25 μ m.
The invention has the beneficial effects as follows:
1, with of mode and the solar silicon cell positive electrode printed pattern stack contrast of standard silk screen plate figure with zero inclination; And the spacing of the adjacent warp at the thin grid line of the corresponding solar silicon cell positive electrode printed pattern place through increasing silk screen plate; Guaranteed that thin grid line can not coincide with the warp of silk screen plate; And printing is evenly effectively improved the conversion efficiency of every solar silicon cell;
2, directly be contracted to 10-25 μ m through line, thin grid line is reduced with the area that the silk screen plate parallel overlaps, can not produce broken string when having guaranteed printing, the conversion efficiency of every solar silicon cell is improved the graticule of silk screen plate;
3, directly increase to original 1.5-2 doubly through the warp of the positive electrode silk screen plate that solar silicon cell positive electrode printed pattern is outer, the line of parallel; Solve the problem that causes silk screen plate intensity to reduce through distance between centers of tracks because of strengthening, and reduced the possibility that thin grid line 21 overlaps with warp 11.
Description of drawings
Fig. 1 is the enlarged diagram of existing solar energy positive electrode silk screen plate;
Fig. 2 is the enlarged diagram of solar energy positive electrode silk screen plate of the present invention.
Among the figure: silk screen plate 1, silk screen plate warp 11, silk screen plate parallel 12, the thin grid line 21 of positive electrode image.
The specific embodiment
To combine Figure of description below, the present invention will be further described.
The positive electrode silk screen plate manufacturing approach that a kind of solar silicon cell conversion ratio is high comprises the steps:
(1) the solar silicon cell positive electrode printed pattern and the standard silk screen plate figure that the client are provided are input in the correspondent computer software, like the contrast that superposes of drawing softwares such as AutoCAD;
(2) according to the analysis of computer software, the spacing of the adjacent warp at the thin grid line of the corresponding solar silicon cell positive electrode printed pattern place of adjusting silk screen plate makes its 2-3 that increases to primary leading doubly;
(3) the line footpath of the warp of the positive electrode silk screen plate outside the adjustment solar silicon cell positive electrode printed pattern, parallel is to original 1.5-2 times;
(4) the adjusted positive electrode silk screen plate figure of output from computer software adopts the mode of electroforming or little cutting to accomplish the manufacturing of silk screen plate according to the figure of exporting.
Standard silk screen plate figure in the high positive electrode silk screen plate manufacturing approach of aforementioned solar silicon cell conversion ratio in the step (1) contrasts with the stack of solar silicon cell positive electrode printed pattern with zero mode that tilts.
The live width of thin grid line is about 35 to 50 μ m in the solar silicon cell positive electrode printed pattern; Spacing between the adjacent thin grid line is 2.0-2.5mm; The line of warp, parallel directly is about 16 μ m in the common positive electrode silk screen plate; Spacing between the adjacent warp is about 50 μ m, thereby nearly 40 warps between adjacent two thin grid lines, when standard silk screen plate figure superposes with solar silicon cell positive electrode printed pattern with zero mode that tilts; Thin grid line coincides with warp probably; But publish picture through software earlier through above-mentioned steps, utilize the enlarged diagram of the positive electrode silk screen plate that method processing and manufacturings such as electroforming process or little cutting become as shown in Figure 2 then, the spacing of the adjacent warp 11 at the thin grid line of corresponding solar silicon cell positive electrode printed pattern 21 places through increasing silk screen plate 1 according to design demand; Guaranteed that thin grid line 21 can not coincide with the warp 11 of silk screen plate 1, and printing evenly.
