Abstract
The utility model discloses a back electrode for reducing unit consumption. The back electrode consists of two electrodes which have structures and are parallel to each other; each electrode is divided into segments with different lengths; and the distances between adjacent segments are different. The back electrode has the beneficial effects of reducing the printing cost by about 30%, keeping the efficiency or slightly enhancing by 0.05% and not obviously changing the product appearance.
Description
Technical field
The utility model relates to solar cell back face electrode.
Background technology
Along with the increase in demand of the world to new forms of energy, the sales volume of solar battery sheet is also become better and better, and back electrode is the important component part of solar battery sheet.A kind of back electrode of the prior art is as shown in Figure 1, is made up of the electrode that two-strip structure is identical.And during this back electrode silk screen printing, the slurry of use is more, and cost is higher.
The utility model content
The purpose of the utility model provides a kind of backplate that reduces unit consumption, solves the cost of manufacture problem of higher that exists in the prior art.
The technical scheme that the utility model adopted is, a kind of backplate is provided, and is made up of the electrode that two-strip structure is identical and parallel, and every strip electrode is by the segmentation of different length, and the spacing between per two segment electrodes is different.
The beneficial effect of the utility model is: make printing cost reduce about 30%, efficient is kept and is slightly promoted 0.05%, and product appearance does not have significant change.
Description of drawings

Fig. 2 the utility model backplate structure chart;
Every section backplate structural representation of Fig. 3 the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model technical scheme is elaborated
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of backplate is made up of the electrode that two-strip structure is identical and parallel; Every strip electrode is by the segmentation of different length; Be divided into five sections like electrode, from top to bottom, first segment electrode 11 and the 5th segment electrode 12 are of a size of 20 ± 0.5mm; The measure-alike of second segment electrode 21 and the 4th segment electrode 22 is 14.5-15.5mm, and the 3rd segment electrode 31 is not all 9.5mm-10.5mm with the size of other four segment electrodes; The spacing of adjacent both ends, from top to bottom, the first intersegmental distance 41 is identical with the spacing of the 4th intersegmental distance 42, and size is 6.5-7.5mm; The second intersegmental distance 51 is identical with the spacing of the 3rd intersegmental distance 52, and size is 9.97-10.97mm.
Every strip electrode edge is provided with sawtooth, and vertically the spacing C2 between sawtooth is 0.5-0.7mm, and vertically the width of sawtooth C3 is 0.5-0.7mm, and the spacing B1 between horizontal sawtooth is 0.46-0.5mm, and horizontal sawtooth B2 is of a size of 0.46-0.5mm.
Every strip electrode width A2 is 2.35-2.45mm.In addition, A1 representes the size of every segment electrode among the figure, and C1 representes the length of vertical sawtooth.
Design in the utility model can make printing cost reduce about 30%, and efficient is kept and slightly promoted 0.05%, and product appearance does not have significant change.
It should be noted last that; Above embodiment only is used to explain the technical scheme of the utility model and is unrestricted; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the claim scope of the utility model.
