Abstract
The utility model discloses a front main grid line structure of a crystalline silicon solar cell. The main grid line zone of the crystalline silicon solar cell is provided with parallel non-printing paste strips which are in uniform distribution and perpendicular to a main grid line. The parallel non-printing paste strips are composed of a single parallel non-printing paste strip or a plurality of independent non-printing paste zones. The single parallel non-printing paste strip is a rectangle, a rounded rectangle or an ellipse. According to the utility model, the single parallel non-printing paste strip or the plurality of independent non-printing paste zones are used, thereby greatly improving tension of an electrode by a rang more than 30%, and reducing the use mount of silver paste.
Description
Technical field
The utility model relates to crystal-silicon solar cell front main grid line (electrode) figure and structure.
Background technology
Chinese patent ZL200910182395 has reported the circular array point of non-printing spreading mass of the sealing that the employing multiple row is parallel with main grid line (claiming again electrode) or the array point main grid line of the non-printing spreading mass vertical with the main grid line that be interrupted, as shown in Figure 3, due to the main grid line that has adopted new construction, the electrode pulling force has obtained certain lifting.Along with the technical development of solar cell, the pulling force of electrode has whole downward trend, in order to ensure the reliability of establishment of component, the pulling force of electrode has been proposed to strict requirement.But its even point of slurry (being also the adhesive spots of electrode) of emphasizing main grid line vertical direction is inadequate, in fact electrode pulling force index is more emphasized is the strength of peeling off while peeling off, and evenly point is more important for the slurry of main grid line in lateral attitude.Simultaneously, along with the development of photovoltaic industry, the existence that constantly reduces unit cost and be each enterprise this, and wherein the cost of slurry has occupied a very important part in the cost of manufacture of whole solar cell.Based on saving the silver paste consumption and promoting the electrode pulling force, the utility model redesigns the structure of main grid line, reducing or not increasing under the prerequisite of silver paste consumption, has further promoted the electrode pulling force.
The utility model content
The utility model purpose is that solve the technical problem that the electrode pulling force need to improve: the structure to the main grid line is redesigned, and reducing or not increasing under the prerequisite of silver paste consumption, has further promoted main grid line (main electrode) electrode pulling force.
The technical scheme of the utility model technical solution problem is: crystal silicon solar energy battery front main grid line structure, be provided with the parallel non-printing slurry bar be uniformly distributed perpendicular to the main grid line in the main grid line zone of crystal silicon solar energy battery, parallel non-printing slurry bar is that wall scroll or a plurality of discrete non-printing slurry zone form.
Further, the parallel non-printing slurry bar of described wall scroll is rectangle, round rectangle or ellipse.As shown in Figure 1.
The beneficial effects of the utility model are, by the single-row a plurality of non-printing slurries of non-printing zone, the pulling force of electrode are significantly promoted, and the lifting amplitude, more than 30%, can also reduce the consumption of silver paste.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is another example schematic of the present utility model.
Fig. 3 is the schematic diagram with the utility model present technology figure as a comparison.
Embodiment
Below in conjunction with accompanying drawing and example, utility model is described.
Shown in Fig. 1, the parallel non-printing slurry bar of wall scroll is rectangle, can be also the enclosed shape that round rectangle or ellipse, trapezoidal, the polygon that comprises whole growth strip or multi sphere line form.
As shown in Figure 2, the non-printing zone of the single-row rectangle of design in the electrode of cell piece, described non-printing slurry bar is discrete non-printing slurry zone, and discrete non-printing slurry zone is closed area, and zone, described closed area is perpendicular to the position of main grid line is parallel and is uniformly distributed; Each closed area is a kind of in the enclosed shape that forms of rectangle, circle, ellipse, polygon or multi sphere line.With the figure that adopts patent ZL200910182395 report in Fig. 3, compare, pulling force promotes 99.4%, and the slurry consumption slightly reduces.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Have and usually know the knowledgeable in technical field under the utility model, within not breaking away from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection range of the present utility model is as the criterion when looking claims person of defining.
