Abstract
The utility model, which belongs to the crystalline silicon solar cell slice field, particularly relates to grid lines of a solar cell slice. The grid lines comprise main grid lines and fine grid lines, wherein the main grid lines and fine grid lines are perpendicular to each other. The main grid lines include a plurality of grid segments that are connected by fine grid lines; position alignment holes are arranged on the grid segments that are sheet-shaped grid lines; and the main grid lines are formed by series connection of the grid segments. Position alignment holes are arranged on the grid segments at two ends of the main grid lines; and hollow holes are arranged on the grid segments at the middle portions of the main grid lines. Besides, narrowed segments are arranged at two ends of the main grid lines. According to the utility model, the non-welded segments of the main grid lines on the solar cell slice employ the fine grid lines and the welded segments employ grid segments, wherein the grid segments are connected in series by the fine grid lines to form the main grid lines; and the hollow holes are arranged on the grid segments. Therefore, the usage amount of silver pastes is reduced under the circumstances that the product performance and the output power of the assembly are not influenced, thereby lowering the production cost.
Description
Technical field
The utility model belongs to the crystal silicon solar cell sheet field, is specifically related to a kind of solar battery sheet grid line.
Background technology
Along with the ag material rise in price, it is increasing that silver is starched ratio shared in the solar module cost.The silver slurry is used for thin grid and main grid in solar cell silk screen printing, the main grid line can be collected the electric current that solar cell is come from thin grid line conduction, and as the welded substrate that welds welding.General main grid line is 2 to 3, and bandpass needs to consume 35% and 50% of total printing slurry 1.5 to 1.8mm." positive gate electrode of solar cell " such as application number " 201110070296.0 ", it comprises the main grid line that is distributed in the solar battery sheet surface and the secondary grid line that is connected with main delete line, its main grid line is the grid line of whole piece even thickness, and the slurry that consumes during production is more, and production cost is high.
The utility model content
The purpose of this utility model is to provide a kind of silver slurry use amount few for addressing the above problem, the solar battery sheet grid line that production cost is low.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
A kind of solar battery sheet grid line comprises mutual vertically disposed main grid line and thin grid line, and it is characterized in that: described main grid line comprises a plurality of grid sections, connects by thin grid line between the described grid section, is provided with registration holes on the described grid section.
Adopt thin grid line in the non-welding position of main grid line, saved the use amount of silver-colored slurry.
Contraposition when carrying out secondary printing that registration holes on the grid section is used for cell piece, avoid repeating print for twice dislocation may appear, ghost phenomena affects end product quality.
As preferably, described grid section is the sheet grid line.
As preferably, described main grid line is made of 4-10 grid section series connection.
As preferably, described registration holes is arranged on the grid section at main grid line two ends.
As preferably, be provided with hollow hole on the grid section at described main grid line middle part.
As preferably, described main grid line two ends are provided with the section of dwindling.
As preferably, described registration holes diameter is 0.4-1.2mm.
As preferably, described hollow hole is square opening.
As preferably, described square hole edge length is 0.3-0.7mm.
Main grid line two ends are in tapered reduction section and the grid section hollow hole to be set, and have all saved the use amount of silver-colored slurry.
In the situation that does not affect IV test stepping and assembly power output, reduce the use amount of silver slurry.
In sum, the utlity model has following beneficial effect:
1, the non-welding section of main grid line on this solar battery sheet adopts thin grid line, welding section adopts the grid section, the logical thin grid line series connection of grid section consists of the mode of main grid line, and in the grid section hollow hole is set, this structure is in the situation that does not affect properties of product and assembly power output, reduce by 20% silver slurry use amount, reduced production cost;
Contraposition when 2, the registration holes on the grid section is used for cell piece and carries out secondary printing, avoiding repeating print for twice dislocation, ghost phenomena to occur, has improved end product quality.
