Description
Technical field
The utility model belongs to technical field of solar batteries, is specifically related to a kind of solar battery front side grid structure with secondary main gate line.
Background technology
Current solar cell silk screen printing technology adopts the mode of main grid and thin grid square crossing to collect electronics, and owing to being subject to the restriction of the inspection process of current silk screen printing material used and solar cell complexity, the method of the conversion efficiency of solar battery front side shading-area and then raising solar cell is reduced by the width reducing front main grid and thin grid, almost reach bottleneck, and reduction cell piece front weight in wet base will certainly affect the decay of battery and the welding pulling capacity of main grid simply, so under the prerequisite not affecting solar cell properties, the conversion efficiency being promoted crystal silicon solar energy battery by existing technique is almost impossible.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of solar battery front side grid structure with secondary main gate line, this structure effectively can reduce the series resistance of thin grid line, reduce silver slurry to consume and front weight in wet base, improve battery conversion efficiency, reduce cell piece decay, reduce cell piece EL blackout.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: a kind of solar battery front side grid structure with secondary main gate line, comprise paralleling and be located at main gate line on crystal silicon chip front and thin grid line, and through time main gate line of many between described main gate line and described thin grid line.
Described many time main gate line are with described main gate line and the perpendicular setting of thin grid line and contact with described main gate line and thin grid line.
Described many time main gate line are preferably 8, are parallel to each other and interval is uniformly distributed.
Described main gate line is preferably two, and arranges separately with described thin grid line.
Every root main gate line is made up of multiple main grid line segment, and the spacing of adjacent main grid line section is identical not to be connected.
Every root main gate line is preferably made up of 8 main grid line segments.
The utility model tool has the following advantages: the solar battery front side grid structure with secondary main gate line in the utility model, cell piece front side silver paste consumption decline 10%-20% can be made, front weight in wet base can be reduced, effectively can also reduce the series resistance of thin grid line, battery efficiency 0.05%-0.15% can be improved, reduce cell piece decay, reduce the EL blackout of cell piece.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model has the solar battery front side grid structure of secondary main gate line.
Embodiment
Below in conjunction with accompanying drawing, this device is described further.
As shown in Figure 1, a kind of solar battery front side grid structure with secondary main gate line, comprises paralleling and is located at main gate line 1 on crystal silicon chip front and thin grid line 2, and through many main gate line 3 between main gate line 1 and thin grid line 2.
Wherein many time main gate line 3 contact with main gate line 1 and thin grid line 2 with main gate line 1 and the perpendicular setting of thin grid line 2.
Many time main gate line 3 are 8, are parallel to each other and interval is uniformly distributed and is not connected.
Main gate line 1 is two, and arranges separately with thin grid line 2.
Every root main gate line is made up of multiple main grid line segment 4, and the spacing of adjacent main grid line section is identical.
Every root main gate line is made up of 8 main grid line segments.
Wherein adjacent thin grid line (removing main gate line region) spacing is identical and width that is every thin grid line of root is identical.
The present embodiment is mainly through carrying out layout again to main gate line 1 and thin grid line 2, the design that front cell piece grid line structure adopts main gate line 1 to parallel with thin grid line 2, add eight main grids 3 in addition and run through whole cell piece front, the electronics that thin grid line 2 is collected is responsible for be pooled in main gate line 1, thus electronics is derived, main gate line 1 adopts 2BB eight sections (being made up of 8 main grid line segments) to design, effectively can reduce slurry consumption (front side silver paste consumption decline 10%-20%) and front weight in wet base, the series resistance of the thin grid line 2 of effective reduction, improve battery efficiency (improving 0.05%-0.15%), reduce cell piece decay, reduce the low EL blackout of battery.
More than enumerate specific embodiment to be described the utility model.It is to be noted; above embodiment is only for the utility model is described in further detail; do not represent protection range of the present utility model, the nonessential amendment that other people make according to prompting of the present utility model and adjustment, still belong to protection range of the present utility model.
