Abstract
A kind of more main grid solar cells, including main grid and carefully delete, the main grid and it is thin delete between square crossing connect, the main grid is made of two linear type grid lines being mutually parallel, it is welded by several solder joints between two linear type grid lines, the solder joint is oval solder joint；The advantageous effect of the technical program is：The reason of string resistance is formed is that the spacing between main grid is larger and causes, main grid is improved to use two linear type grid lines by the utility model, and it is connected in-between by the form of solder joint, greatly shortens the spacing between main grid, to solve the problems, such as that string resistance is larger；The solder joint between two grid lines of the utility model pair is using oval solder joint scheme simultaneously, which can effectively reduce shading-area, and increase the reflectivity of light, to further increase the power and efficiency of cell piece.
Description
Technical field
The utility model is related to photovoltaic technology field, in particular to a kind of more main grid solar cells.
Background technology
Currently, in the manufacturing process of solar cell, welding welding main grid is mostly used, but due to shading after welding welding
Area is big, cause reduce battery efficiency and component power situation, and component string resistance it is larger, influence cell piece efficiency and
Power；And existing battery grid line structure makes silver paste usage amount larger, is unfavorable for reducing production cost.
Invention content
The utility model provides a kind of multiple-grid line solar cell in order to solve the problems existing in the prior art, by grid
Cable architecture, which is improved, solves the problems, such as that the prior art is low and silver paste usage amount is big there are efficiency, and the utility model can reduce cell piece
Silver paste usage amount, and promote battery and component efficiency.
To achieve the above object, the utility model uses following technical scheme：A kind of more main grid solar cells, including
Main grid and carefully delete, the main grid and it is thin delete between square crossing connect, the main grid is by two linear type grid lines being mutually parallel
It forms, is welded by several solder joints between two linear type grid lines, the solder joint is oval solder joint；The technical program
Advantageous effect is：The reason of string resistance is formed is that the spacing between main grid is larger and causes that main grid is improved to by the utility model
It using two linear type grid lines, and is connected in-between by the form of solder joint, greatly shortens the spacing between main grid,
To solve the problems, such as that string resistance is larger；The solder joint between two grid lines of the utility model pair, should using oval solder joint scheme simultaneously
Oval solder joint can effectively reduce shading-area, and increase the reflectivity of light, to further increase the power of cell piece
And efficiency.
Preferably, the main grid and it is thin delete between junction be welded with arc-shaped contact point；The technical program is further
The formation for reducing string resistance, the fill factor of lifting assembly improves collection to electric current.
Preferably, the main grid at least 12；The technical program by further increase main grid quantity reduce main grid it
Between spacing and decrease the usage amount of silver paste to reduce the formation of string resistance, in a disguised form reduce production cost.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of more main grid solar cells, including main grid and carefully delete 1, the main grid and it is thin delete between it is vertical
Interconnection, the main grid is by two linear type grid lines being mutually parallel（2、3）Composition, two linear type grid lines（2、3）
Between welded by several solder joints 4, the solder joint 4 is oval solder joint.
Preferably, the main grid（2、3）It is welded with arc-shaped contact point 5 with the junction carefully deleted between 1.
Preferably, the main grid（2、3）At least 12.
The basic structure and key property and the advantages of the utility model of the utility model has been shown and described above.To reality
It is described with novel specific embodiment, but not to the limitation of scope of protection of the utility model, the technology of the industry
Personnel do not depart from practicality it should be appreciated that above-described embodiment and the only basic operating procedure of the utility model described in explanation
Under the premise of novel spirit and scope, the utility model also has various changes and improvements, these changes and improvements, which are both fallen within, to be wanted
It asks in the scope of the utility model of protection.The utility model requires protection scope is by the attached claims and its equivalent circle
It is fixed.
