Abstract
The utility model provides a solar cell sheet and belongs to the technical field of solar cell sheets, so as to solve the problem that the existing solar cell sheet is high in production cost. The solar cell sheet comprises a plurality of main gate lines printed on the front surface and the back surface of the cell sheet and a plurality of auxiliary gate lines connected with the main gate lines; the main gate lines comprise a plurality of parallelly-arranged main gate single lines; the main gate single lines are separately and independently printed on the cell sheet; and a distance exists between adjacent main gate single lines. The solar cell sheet has the advantages of low production cost and large welding pull force.
Description
Technical field
The utility model belongs to solar battery sheet technical field, relates to a kind of solar battery sheet.
Background technology
Solar battery sheet becomes electric energy by photovoltaic effect by transform light energy, and what in cell piece, play collection electric charge and electric action is the gate line electrode of front and back, and the slurry that gate line electrode is silver-colored simple substance by main material is made by silk screen printing.The gate line electrode of solar battery sheet front and back generally includes 2~3 compared with thick main grid line and a lot of thin and close secondary grid line of root, and secondary grid line is mainly collected the photogenerated current producing in cell piece; Main grid line is connected with secondary grid line, and the electric current that secondary grid line is collected collects output, and as the welded substrate of the interconnecting strip that adjacent cell sheet is connected (welding).But because silk screen printing silver used slurry cost is higher, especially printing main grid line, to expend silver slurry more, causes the production cost of solar battery sheet higher.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, thereby has proposed the solar battery sheet that a kind of silver slurry consumption that can reduce printing main grid line reduces solar battery sheet production cost.
The purpose of this utility model can realize by following technical proposal: a kind of solar battery sheet, comprise and be printed on the some piece main grid line of cell piece just, on the back side and many secondary grid lines that are connected with above-mentioned main grid line, it is characterized in that: described main grid line comprises the some main grid single lines that are arranged side by side, described main grid single line is separately printed on independently on cell piece and between adjacent main grid single line and has spacing each other.
In above-mentioned a kind of solar battery sheet, the cross section of described main grid single line is semicircle.
In above-mentioned a kind of solar battery sheet, between described adjacent two main grid single lines, spacing is 0~100 micron.
In above-mentioned a kind of solar battery sheet, described main grid single line is the six roots of sensation.
Compared with prior art, this solar battery sheet has following several advantage:
1, the width due to main grid line is constant, and the main grid line that so separate main grid single line forms is used this consumption to reduce at silver slurry, thereby can reduce costs;
2, the cross section of main grid line is separated semicircle face, and the surface area of relatively existing main grid line is larger, while welding so and welding contact area also large, contribute to increase the welding pulling force of unit width welding.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing main grid line.
Fig. 2 is the structural representation of the main grid line in this cell piece.
Fig. 3 is the cross sectional representation of existing main grid line.
Fig. 4 is the main grid line cross sectional representation in this cell piece.
In figure, 1, cell piece; 2, former main grid line; 3, main grid line; 4, main grid single line.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 2, this solar battery sheet comprises and is printed on the some piece main grid line 3 of cell piece 1 just, on the back side and many secondary grid lines that are connected with main grid line 3, main grid line 3 comprises the main grid single line 4 that the six roots of sensation is arranged side by side, and main grid single line 4 is separately printed on independently on cell piece 1 and between adjacent main grid single line 4 and has spacing each other.Because the width of main grid line 3 is constant, existing main grid line 3 is banded, and as shown in Figure 1, the main grid line 3 that so separate main grid single line 4 forms is used this consumption to reduce at silver slurry, thereby can reduce costs.
Between adjacent two main grid single lines 4 in the present embodiment, spacing is 50 microns, the spacing increasing between main grid single line 4 can impact with contacting of main grid line 3 test probe, can compensate by disposable increase number of probes, recruitment can be determined according to lines spacing size.
As shown in Figure 4, the cross section of main grid single line 4 is semicircle.And the cross section of existing former main grid line 2 is continuous cross section, as shown in Figure 3.The cross section of this main grid line 3 is six separated semicircle faces, and the surface area of relatively existing former main grid line 2 is larger, while welding so and welding contact area also large, contribute to increase the welding pulling force of unit width welding.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (4)
