Be illustrated in figure 1 steel wire 30 half tone.Formed by the yarn up and down weaving in many warp thread and weft yarn two direction, there is anastomose 31 on steel wire 30 surface Formation rule convex-concave surface.The spacing (pitch) of warp thread and warp thread is about 30 ~ 100 μm.At anastomose place, the height of grenadine thickness about two one thread.
And the finger electrode pattern openings of existing half tone (i.e. macromolecular material emulsion opening of producing after development) is random, Fig. 2 shows finger electrode pattern openings 61 and 62, does not do contraposition process.Therefore, anastomose 31 may just at the right time at finger electrode pattern openings 61 partially midline position, and anastomose 31 also may in the position of inclined side, just like finger electrode pattern openings 62.In Fig. 2, grenadine has been turned an angle, about 45 °, can reduce the anastomose number that finger electrode pattern openings is passed through like this.But anastomose is in finger electrode pattern openings, and to the left, to the right or center line is exactly random, with the spacing of finger electrode pattern openings and the spacing of warp thread and may be different.But, as shown in Figure 2, opening by anastomose screening rate also more than a lot of less when grenadine does not turn as shown in Figure 3.Fig. 3 shows anastomose 31 in the median line of finger electrode pattern openings 61 and the side to the left of 62.
Therefore, the non-contraposition process of above-mentioned finger electrode pattern openings, contains many anastomoses 31.Grenadine thickness not containing anastomose 31 in grenadine is less than the thickness at anastomose 31 place, when screen painting, in grenadine from the opening part of anastomose more at a distance, metal paste falls more smoothly, and it is quite different near anastomose 31, these position metal pastes easily blocked or residual slurry, result will make the metal paste uneven thickness of finger electrode.Particularly with after this screen painting some, metal paste uneven thickness problem more can be highlighted.

Detailed description of the invention
One as described in the prior art, and when the solar cell half tone of applied metal grenadine braiding is with wire mark finger electrode, anastomose is encountered in inevasible meeting, and makes metal paste blanking when substrate, has the problem of thickness difference of height inequality.
The present invention can solve the above problems.According to the first embodiment of the present invention, the present invention does not change metal grenadine, but time the photoetching of high-molecular photosensitive emulsion (micro-shadow), adopts counter-point that the left and right two edges of finger electrode pattern openings are located in two row's lines of the anastomose of metal grenadine respectively.
Please refer to the half tone 30 shown in Fig. 5, diagram, according to the first embodiment of the present invention, is taked counter-point, all anastomoses is all located at the left and right two edges of finger electrode pattern openings 61A, 62A.Such as, when taking this scheme, when grenadine has turned 45 °, the width of finger electrode has been the most approximately 0.707 times of grenadine spacing, namely
Spacing due to finger electrode may not be that the integral multiple of 0.707* grenadine spacing is (at this, symbol " * " representative " is taken advantage of "), therefore, just likely when first finger electrode pattern openings 61A has met condition (anastomose is all located at the left and right two edges of finger electrode pattern openings), second finger electrode 62 has just run counter to above-mentioned condition, therefore, solution goes design finger electrode spacing according to the integral multiple of 0.707* grenadine spacing as far as possible.Another solution allows finger electrode pattern openings within former precalculated position ± 50 μm, seeks without anastomose or the minimum part fine setting of anastomose.After finger electrode 62A is just through contraposition calculating, the position (original position is set to 62) after adjustment.
Therefore, before photoetching finger electrode pattern openings, obtain the relation of spacing and the 0.707* grenadine spacing first calculating finger electrode, according to this relation contraposition macromolecule emulsion pattern openings, to make the opening of all emulsion patterns, changing position within ± 50 μm.
Above-mentioned miter angle, just for convenience of explanation, not in order to limit, such as, in 15 degree of-60 degree is all feasible.
According to the second embodiment of the present invention, metal grenadine does not turn an angle, and namely allows warp thread in the vertical direction, and weft yarn in the horizontal direction, please refer to Fig. 6.And after contraposition, the finger electrode pattern openings 61A of whole piece drops on (finger electrode pattern openings width still keeps being less than the spacing of warp thread) between two warp thread.
Just like the first embodiment, the spacing of finger electrode pattern openings may not be the integral multiple of grenadine spacing, and therefore, some finger electrode pattern openings position must within ± 50 μm, and the position of variation finger electrode, as Fig. 6, is adjusted to 62A by opening by 62.So can make in all finger electrode pattern openings, just to only have weft yarn (or warp thread) neither one anastomose 31.
Therefore, before photoetching finger electrode pattern openings, obtain the relation of spacing and the grenadine spacing first calculating finger electrode, according to this relation contraposition macromolecule emulsion pattern openings, to make the opening of all emulsion patterns, changing position within ± 50 μm.Compared with the first embodiment, the width design of the finger electrode of the second embodiment, feasible value is larger.
The present invention has following advantage:
(1) still continue to use the half tone that existing Metal Yarns is made into, cost can not increase, and this half tone easily obtains.
In (2) first embodiments, the restricted width system of finger electrode is more, but neither one anastomose, in second embodiment, the width of finger electrode can wider (for the first embodiment), and still there is no anastomose, although inevitable finger electrode pattern openings still has warp thread or weft yarn, the half that simple warp thread or weft yarn thickness only have anastomose thick.Therefore the even blanking of metal paste is easily reached.
The foregoing is only a preferred embodiment of the present invention, and be not used to limit claim of the present invention; Under all other do not depart from disclosed spirit, the equivalence that completes changes or modifies, and all should be included in claims.
