Abstract
The utility model relates to a kind of annular thin grid polycrystalline cell piece.It is characterized in that being comprised of anyhow alternate thin grid line and main grid line, the width of described thin grid line is 35 microns, and the number of described thin grid line is 70, the outer setting housing of thin grid line, and described housing is connected end to end between two by each thin grid line.Described main grid line is 3, and the spacing between adjacent main grid line is 52 millimeters.The polycrystalline cell piece of the utility model structure has effectively reduced the use amount of silver slurry in production process, and battery still possesses original performance, effectively reduces production cost, improves the performance of enterprises.
Description
Technical field
The utility model relates to a kind of annular thin grid polycrystalline cell piece.
Background technology
Crystalline silicon battery plate has obtained batch production and has used through development recent years, be limited by foreign country two anti-, no matter be that enterprise or industry all run into relative stern challenge, enterprise will survive just must have innovation at present, also need strictly to control cost simultaneously, particularly reduce production costs.
Utility model content
The problem that the utility model exists for existing cell panel structure, provides a kind of annular thin grid polycrystalline cell piece, can effectively reduce the accounting of silver slurry in cell piece structure, reduces production costs, and improves the performance of enterprises.
For this reason, the utility model is taked following technical scheme: a kind of annular thin grid polycrystalline cell piece, it is characterized in that being formed by anyhow alternate thin grid line and main grid line, the width of described thin grid line is 35 microns, the number of described thin grid line is 70, the outer setting housing of thin grid line, described housing is connected end to end between two by each thin grid line.
Described main grid line is 3, and the spacing between adjacent main grid line is 52 millimeters.
In order to reduce silver slurry consumption, we, and measure 360 good order half tones and guarantee that the grazing of thin grid line printing guarantees that cell piece outward appearance is unaffected with crossing China ink by reducing the width of thin grid line and reducing the method for grid line number at half tone design aspect; If other manufacture crafts are constant owing to certainly will increasing cell piece contact resistance after thin grid line minimizing, and the fill factor, curve factor that affects cell piece finally affects cell piece performance, therefore we,, by being connected between two end to end of the thin grid line of cell piece, also can reduce contact resistance in this way to a certain extent.
The polycrystalline cell piece of the utility model structure has effectively reduced the use amount of silver slurry in production process, and battery still possesses original performance, effectively reduces production cost, improves the performance of enterprises.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Annular thin grid polycrystalline cell piece as shown in Figure 1, it is comprised of anyhow alternate thin grid line 2 and main grid line 3, and the width of thin grid line 2 is 35 microns, and the number of thin grid line 2 is 70, the outer setting housing 1 of thin grid line 2, housing 1 is connected end to end between two by each thin grid line 2.Main grid line 3 is 3, and the spacing between adjacent main grid line 3 is 52 millimeters.
In order to reduce silver slurry consumption, we, and measure 360 good order half tones and guarantee that the grazing of thin grid line printing guarantees that cell piece outward appearance is unaffected with mistake is black by reducing the width (being reduced to current 35 microns from original 40 microns) of thin grid line and reducing the grid line number method of (will lack 70 from current 85) at half tone design aspect; If other manufacture crafts are constant owing to certainly will increasing cell piece contact resistance after thin grid line minimizing, and the fill factor, curve factor that affects cell piece finally affects cell piece performance, therefore we,, by being connected between two end to end of the thin grid line of cell piece, also can reduce contact resistance in this way to a certain extent;
In order better to reduce diffusing procedure square resistance resistance, can realize by reducing the method for diffusion time (being reduced to 20 minutes from original 25 minutes) and the little nitrogen flow of reduction (being reduced to 800ml/mim from original 1000ml/mim) in addition.Facts have proved that every cell piece of use the method can reduce silver slurry consumption 15%, high-efficiency battery sheet electrical property is had to 0.1% impact, on the almost not impact of high resistant silicon chip electrical property, and the cell piece stable performance of the method making, outward appearance is good.
It needs to be noted, the mode of above-described embodiment only limits to describe embodiment, but the utility model is confined to aforesaid way incessantly, therefore and those skilled in the art can modify easily accordingly within not departing from scope of the present utility model, scope of the present utility model should comprise principle that the utility model discloses and the maximum magnitude of new feature.
