Abstract
The utility model discloses a positive electrode of a crystalline silicon solar cell. The positive electrode comprises a plurality of main grid lines and a plurality of auxiliary grid lines. Each main grid line is distributed at intervals with rectangular apertures, wherein the width of each rectangular aperture is smaller than that of the main grid line, and the spacing distance between the rectangular apertures is larger than the width of a test probe. In the positive electrode of the crystalline silicon solar cell, on the basis that conductive performance of the crystalline silicon solar cell is not influenced, the main grid lines of the positive electrode are designed into a hollow structure with rectangular apertures, so that the using amount of silver paste is greatly saved during printing, production cost of the solar cell is reduced, and market competitiveness is improved.
Description
Technical field
The utility model relates to a kind of positive electrode of crystal silicon solar energy battery.
Background technology
Each solar battery sheet of solar cell simultaneously is distributed with positive electrode, and another opposite face is distributed with back of the body electric field and back electrode.The positive electrode of solar battery sheet generally is comprised of a large amount of auxiliary grid lines and two to three main grid lines, and the electric current that flows through on auxiliary grid line is flowed on the main grid line, after the electric current on the main grid line is flowed to convergent belt again, by terminal box, guides to the battery outer end.Auxiliary grid line on solar battery sheet and main grid line are made template by the solar cell grid line silver slurry are printed onto on solar battery sheet.In order to guarantee the power of solar battery sheet, the width of the main grid line on template there is is certain requirement, the main grid line of the positive electrode of existing solar battery sheet and auxiliary delete line are all whole piece silver lines very close to each other.Print the required silver slurry of auxiliary grid line and main grid line expensive, the price of all kinds silver slurry is all more than 9000 yuan/kilogram, and the consumption of every cell piece front side silver paste, in 0.10-0.13 gram left and right, accounts for 40% of solar battery sheet cost of material now.If can carry out decrease silver slurry use amount by changing grid line structure under the prerequisite that power after the Assurance component encapsulation does not reduce, can reduce undoubtedly the production cost of solar cell, improve the market competitiveness.
The utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of positive electrode of crystal silicon solar energy battery is provided, uses the crystal silicon solar energy battery of this positive electrode, guaranteeing under the prerequisite that its power does not reduce, its silver slurry consumption is few, and the battery cost is low.
For achieving the above object, technical solution of the present utility model is: a kind of positive electrode of crystal silicon solar energy battery, and it comprises many main grid lines and many auxiliary grid lines; It is characterized in that: be intervally distributed with the rectangular opening of width less than the main grid line width on every main grid line, the spacing distance between rectangular opening is greater than the width of test probe.
The utility model is on the basis that does not affect the crystal silicon solar energy battery electric conductivity, the main grid line of positive electrode is designed to engraved structure with rectangular opening, greatly save the consumption of silver-colored slurry during printing, reduced the production cost of solar cell, improved the market competitiveness.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A section enlarged drawing of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the present embodiment comprises three main grid lines 1 and the auxiliary grid line 3 of 70-90 bar.Also two or more, main grid line.Be intervally distributed with the rectangular opening 2 of width less than the main grid line width on every main grid line 1, width is preferably 0.8～1.4mm; Spacing distance between rectangular opening 2 is greater than the width of test probe, and spacing distance is preferably 6～14mm.
Certainly; the utility model also has other various embodiments; in the situation that without prejudice to the utility model spirit and essence; those of ordinary skill in the art can make corresponding change and distortion according to the utility model; number as main grid line and auxiliary delete line; the change of the number of the rectangular opening that distributes on the main grid line, but these corresponding changes and distortion all should belong to the protection range of the utility model claim.
