A length of 156 ± 20mm dereliction grid cell piece equal portions cutting forms.
Its further technical scheme is the dereliction grid cell piece formed for decile cutting, and its length of side isOr
Its further technical scheme is, for weaving the horizontal copper cash of copper network and the cross section of longitudinal copper cash as circle
Shape, square or platypelloid type etc..
Its further technical scheme is that the horizontal copper cash has 4~10.
Its further technical scheme is that longitudinal copper cash has 10~50.
Its further technical scheme is, in the battery strings, the distance between adjacent dereliction grid cell piece for-
2mm~5mm.
The method have the benefit that：
1st, the copper section that copper network is formed in the present invention is circular, square or platypelloid type etc., after photovoltaic module is made,
Relatively conventional main grid technique, effective shading-area can be reduced 30% or so, while reduce ohmic loss, component general power
3% or so can be improved；
2nd, present invention uses without main grid structure, the technique for having abandoned traditional welding interconnecting strip welding, directly using volume
It is made into the technique that the copper network of type is intersected and welded with the thin grid of battery.Touching between secondary grid in the copper network and battery of knitting forming
Point has thousands of, more optimizes with the path of fine fisssure position electric current conduction in hidden split of silicon chip, therefore due to loss caused by hidden split
It is greatly reduced, including component hot spot problem can also greatly reduce.
3rd, the present invention directly uses the copper network of knitting forming, and the surface of copper network carries out applying tin-lead or electroplating processes,
Carry out putting welding, single series welding can be carried out and connect, can also go here and there while weld more, greatly promote the production efficiency of photovoltaic module.
What is more important is directly welded to connect because component battery is without main grid using the copper network of knitting forming with thin grid, battery
Ag material dosage can reduce 70% or so.
4th, the present invention replaces traditional welding interconnecting strip using the copper network of knitting forming, cell piece and battery in component
Spacing between piece can also realize the lamination between cell piece with very little even zero, form imbrication pattern and use spacing
For negative technology mode, component conversion efficiency is greatly improved.
5th, the present invention replaces traditional welding interconnecting strip using the copper network of knitting forming, because copper mesh is without main grid electricity
It is distribution welding on pond, so contact area produces heat energy and reduced, so as to optimization component temperature coefficient.
6, the present invention replaces traditional welding interconnecting strip using the copper network of knitting forming, and the thickness of the copper mesh of braiding can
By being flattened under high temperature and electric current spot welding and pressure, to realize no salient point.
7, the cell piece front that the present invention uses is without main grid, in pad corresponding to the thin grid Position Design that same copper mesh contacts.

Embodiment
The present invention includes dereliction grid cell piece and copper network.
Fig. 1 is the schematic diagram of the embodiment 1 of copper network.Fig. 2 is the schematic diagram of the embodiment 2 of copper network.Copper network is more
Root longitudinal direction copper cash and Duo Gen transverse direction copper wire wovens form.Horizontal copper cash is generally 4~10, and longitudinal copper cash is generally 10~50
Root, specific quantity can be selected as needed.Copper network in Fig. 1 has 4 horizontal copper cash；Copper network in Fig. 2 has 6 transverse directions
Copper cash.
Copper cash cross section for weaving copper network is circular, square or platypelloid type, can effectively reduce the screening to sunlight
Gear, and reduce ohmic loss.
Fig. 3 is the front schematic view of dereliction grid cell piece.As shown in figure 3, dereliction grid cell piece has the secondary grid of more transverse directions,
But without the main grid of longitudinal direction.In the present embodiment, dereliction grid cell piece is conventional cell piece, as the length of side be 156 ±
20mm cell piece；Or formed by the cell piece equal portions cutting that the length of side is 156 ± 20mm.
If dereliction grid cell piece is formed by the cell piece equal portions cutting that the length of side is 156 ± 20mm, dereliction grid cell piece
Size dimension beOrCan also be other
Appropriate size.
As shown in Fig. 4~Fig. 6, copper network 2 covers and connects multiple dereliction grid cell pieces 1 of longitudinal arrangement；For two
Adjacent dereliction grid cell piece 1, copper network 2 cover the front of wherein a piece of dereliction grid cell piece, and cover another without main grid
The back side of cell piece；And the infall of the copper cash of copper network 2 and the secondary grid of dereliction grid cell piece 1 welds, and forms battery strings 4.
Reference can be made to can see a horizontal copper cash 21 in Fig. 6, Fig. 6, longitudinal copper cash 22 is mutually perpendicular to secondary grid 11, longitudinal direction
Welded in the place that copper cash 22 and secondary grid 11 intersect.
Again as shown in Figure 5, the battery strings that multiple dereliction grid cell pieces 1 form are connected by copper network 2, relative to traditional
The technique welded between different cell pieces by welding interconnecting strip, the contact between copper network and secondary grid has thousands of, in silicon
Hidden split of piece more optimizes with the path of fine fisssure position electric current conduction, therefore because loss caused by hidden split is greatly reduced, component
Hot spot problem can also greatly reduce.
Because multiple dereliction grid cell pieces in battery strings are welded together by copper network, so without as traditional work
Skill is the same, is welding leaving space, can be apart from can be with very little even zero between adjacent dereliction grid cell piece, and edge is complete
Fitting, saves space, and due to shortening electric current carrying pathway, improve battery efficiency.
Fig. 7 is the schematic diagram of battery component.There are four battery strings 4 in Fig. 7, each battery strings 4 are by 3 dereliction grid cell pieces
1 is formed by connecting.Four battery strings 4 are connected as battery component by busbar 3.
Fig. 8 is copper network while welds the schematic diagram of more file cell pieces.In fig. 8, multiple no main grids of longitudinal arrangement
Cell piece is a file, and copper network 2 covers and connects the dereliction grid cell piece of 3 files simultaneously.In each file, for two
Individual adjacent dereliction grid cell piece 1, copper network 2 cover the front of wherein a piece of dereliction grid cell piece, and cover another dereliction
The back side of grid cell piece.In the dereliction grid cell piece of 3 files, the cell piece within each file is mutually in parallel, file with
Mutually it is in series between file, eventually forms the big string of plate.In the particular embodiment, copper network can simultaneously cover and connect one
The dereliction grid cell piece of individual file, it can also simultaneously cover and connect 2,3 dereliction grid cell pieces down to multiple files.
Above-described is only the preferred embodiment of the present invention, and the invention is not restricted to above example.It is appreciated that this
Other improvement and become that art personnel directly export or associated without departing from the spirit and concept in the present invention
Change, be considered as being included within protection scope of the present invention.
