Abstract
The utility model discloses a positive electrode mesh plate of a solar cell. The positive electrode mesh plate comprises a plate body, wherein thin grid lines and a plurality of nodes, the thin grid line pattern on the plate body is composed of a plurality of *-shaped grid line structure array units, and nodes are located at the central intersection point positions of *-shaped grid line structure array units.
Description
Technical field
The utility model relates to a kind of solar cell Printing screen, relates in particular to a kind of positive electrode Printing screen of solar battery sheet.
Background technology
Current, along with the continuous development of silicon solar cell technologies,, also increasingly high to the requirement of Solar cell performance pursuing cheaply simultaneously.The solar cell manufacturing mainly comprises following step: the silicon chip cutting, and material is prepared; Remove the damage layer; Making herbs into wool; Diffusion system knot; Edge etching, cleaning; The deposition antireflection layer; The printing upper/lower electrode; Burn altogether and form Metal Contact; And battery built-in testing.Wherein the printing of electrode has very large influence to the performance of battery, and the electrode of high-quality performance can improve the transformation efficiency of solar cell to a certain extent effectively.
Traditional positive electrode Printing screen constitutes by some main grid lines and some thin grid lines are vertical each other.Shown in Figure 1 is the sketch map of 156 * 156 crystal silicon solar energy battery positive electrode web plates, and it constitutes by 3 main grid lines 11 and some thin grid lines 12 are vertical each other.The electrode main grid line live width that this traditional screen printing goes out runs through the entire cell sheet greatly and almost, and its large tracts of land has hidden the illuminating area of battery sheet, thereby has reduced solar energy utilization rate.Though those skilled in the art are devoted to reduce to print the line footpath width of thin grid line always, so that increase effective illuminating area of battery sheet, the electric current collection ability of the grid line structure that prints electrode intrinsic is difficult to further improve again.
The utility model content
The utility model causes the capacity gauge of electric current to be difficult to the technical problem that further improves for the gate electrode line that solution conventional solar cell positive electrode screen printing goes out; A kind of novel solar battery sheet positive electrode Printing screen is provided; Its special grid line structure can strengthen the capacity gauge of electric current, thereby improves solar cell heat energy transformation efficiency.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be:
A kind of solar battery sheet positive electrode web plate; Comprise plate body; Plate body is provided with thin grid line and some nodes, and the thin grid line pattern on the said plate body is made up of several " rice " font grid line array of structures unit, and said node is in the middle intersection point place of " rice " font grid line construction unit.
Further, the grid line on the vertical and horizontal direction of said " rice " font grid line construction unit has some branched structures.
Further, the oblique grid line of said " rice " font grid line construction unit also has some branched structures.
As preferably, the main body of said " rice " font grid line construction unit is square.
As preferably, said " rice " font structure vertically and the branched structure on the horizontal direction grid line be symmetrical structure; Further, the line style of branched structure is linear pattern, and the grid line of the branched structure on the same side of same limb is equidistantly parallel each other.
As preferably, the branched structure on the oblique grid line of said " rice " font structure is a symmetrical structure; Further, the line style of branched structure is linear pattern, and the grid line of the branched structure on the same side of same limb is equidistantly parallel each other.
Further, the grid line of each isolated area branched structure of described " rice " font structure is all equidistantly parallel.
The grid line structure of said web plate is made up of some above-described construction units, and as preferably, the grid line structure of said web plate constitutes (n=1 by n * n said grid line construction unit; 2,3,4; 5 wait all suitable natural numbers), the grid line structure of adjacent two unit is interconnected.
The special construction of the electrode of solar battery web plate that the utility model provided has used the topology rule, has the advantage that the electric current collection ability is strong, transfer rate is high through its gate electrode line that prints out, and can effectively improve the transformation efficiency of solar cell.

Fig. 2 is the sketch map according to the solar cell positive electrode web plate structure of an embodiment of the utility model; And
Fig. 3 is the enlarged diagram of 21 parts among Fig. 2.
The specific embodiment
A preferred embodiment of the utility model below will be discussed.But it will be appreciated by those skilled in the art that the detailed description here as to the restriction of the utility model protection domain, the utility model also can be achieved through modification or other equivalent way of this embodiment.
A kind of solar cell positive electrode web plate, its plate body structure is as shown in Figure 2.(promptly 4 * 4) individual " rice " font construction unit 21 constitutes printing zone by 16 on the plate body.Fig. 3 is the enlarged diagram of 21 parts among Fig. 2, and construction unit is made up of a node 31 and some grid lines 32, and main body is a square structure, and the grid line 32 of two unit intersections that all are adjacent links up, and does not promptly have breakpoint; Node 31 and grid line 32 time play the effect of spillage in printing, and seeing through thin grid line 32 and node 31 can be at the identical battery sheet positive electrode of grid line structure plan on formation on the battery sheet and the web plate.
Below describe the construction unit 21 of present embodiment in detail.
Have only a node on said " rice " font construction unit 21, it is in the middle intersection point place of " rice " font grid line construction unit.Said " rice " font construction unit 21 is a skeleton with four grid lines that intersect with Centroid, and it is 8 delta-shaped regions that the skeleton grid line is divided construction unit equally, like delta-shaped region 33.Have linear pattern branched structure grid line a on the vertical and horizontal direction skeleton grid line in described " rice " font structure, have linear pattern branched structure grid line b on the oblique skeleton grid line.In each zone of being cut apart by the skeleton grid line (like zone 33), all grid line a are equidistantly parallel each other with the grid line of the grid line group that grid line b constitutes.The grid line direction of the grid line group that said grid line a, grid line b constitute becomes 22.5 ° with the skeleton grid line at grid line a (or grid line b) place, and promptly α (or β) is 22.5 °.
