The edge of the battery slice, the rear electrode of previous battery slice is the same as next battery slice adjacent thereto
Front electrode is connected by welding.
Further, the rear electrode of the previous battery slice is the same as next battery slice adjacent thereto
The rear electrode is opposite with the front electrode after front electrode stacking setting and stacking, and the welding is in the back side electricity
It is connect between pole and the front electrode and respectively with the rear electrode and the front electrode.
Further, the welding with a thickness of 0.1~0.4mm.
Further, the matrix of the battery slice is the monocrystalline or polysilicon chip of N-type or p-type.
Further, battery slice be PERC solar battery sheet, hetero-junction solar cell piece, TOPCon cell piece,
PERL cell piece or PERT cell piece.
Further, the width of the welding is equal with the front electrode width.
Compared with prior art, a kind of solar energy laminated batteries of the utility model, the back for being sliced a battery by welding
Face electrode is connected with the front electrode of other one battery slice adjacent thereto, thus by two connected batteries be sliced between away from
From shortening to zero, so that the encapsulation quantity of battery increases in the case of same area, the power of battery component is increased；Simultaneously because
There is no ductility in welding connection procedure, it is low to process equipment requirement, and by welding, enhance the reliable of connection
Property.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
The utility model is further described in example.It should be appreciated that specific embodiment described herein is only used to explain this reality
With novel, it is not used to limit the utility model.
Referring to Fig. 1, the schematic diagram of solar energy laminated batteries in the present embodiment, connection structure includes that at least two pieces of batteries are cut
Piece 1 and the welding 2 for being sliced 1 for connecting two neighboring battery, battery slice 1 can be continuously arranged multiple according to the actual situation,
It is corresponding, since battery slice 1 is to be welded after front and back is laminated by a welding 2, it will therefore be appreciated that of welding 2
Number is one fewer than the number of battery slice 1.
Specifically, two surfaces up and down of every piece of battery slice 1 are respectively equipped with a front in conjunction with shown in Fig. 1, Fig. 2 and Fig. 3
Electrode 11 and a rear electrode 12, wherein the length direction setting of front electrode 11 and rear electrode 12 along battery slice 1, front
Electrode 11 and rear electrode 12 are oppositely arranged and are respectively at the two sides edge of battery slice 1, as shown in Figure 1, upper battery is cut
At the left side edge of the upper surface of piece and lower cell piece be equipped with a front electrode 11, then rear electrode 12 be set to upper battery slice and
