Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model is described in detail in example.
It please refers to shown in Fig. 3 to Fig. 4, a kind of solar components 100, including battery strings layer and above battery strings layer
Packaging adhesive film (not shown) and the packaging adhesive film 30 below battery strings layer.Battery strings layer includes the battery of several parallel arrangeds
Piece string, cell piece string include several cell pieces interconnected 20, are connected between cell piece 20 by welding 21.
Packaging adhesive film 30 is equipped with the groove 31 of several parallel arrangeds, the extending direction of groove 31 towards the surface of battery strings layer
It is identical as the extending direction of welding 21, and part recess 31 is corresponded to each other with the position of welding 21.So set, can be by welding
21 parts snap into inside groove 31, improve the contact area of welding 21 and packaging adhesive film 30 on cell piece 20 before being laminated, reach
Increase the purpose of frictional force between the two.
The depth of groove 31 is greater than 0.1mm, and is less than the width of welding 21, and the spacing between adjacent groove 31 is less than weldering
With 21 width.Such as, when welding 21 is the round welding that diameter is 0.25mm, the value range of the depth d of groove 31 is 0.1mm
< d < 0.25mm, the spacing between adjacent groove 31 are less than 0.25mm.Certainly, welding 21 is not limited to as round welding,
