Description
[technical field]
This utility model belongs to solar energy crystal silicon battery component technology field, is specifically related to a kind of reflective solder strip improving welding pulling capacity and photovoltaic module.
[background technology]
Welding is the important raw and processed materials during welding photovoltaic component, and welding is used for connecting cell piece and cell piece, and the quality of welding quality will directly influence the collection efficiency of photovoltaic module electric current, affects the biggest on the power of photovoltaic module.
By welding by the front electrode of first battery and the backplate of second battery, circuit is made to obtain through.
But the whole concave-convex surface reflective structure of welding is unfavorable for welding of welding and battery aluminum back surface field, shows as welding pulling capacity and reduces, affects the long-term reliability of assembly.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of reflective solder strip improving welding pulling capacity and photovoltaic module, and this reflective solder strip can improve welding pulling capacity, does not affect component power output performance simultaneously.
Above-mentioned technical problem of the present utility model is achieved by the following technical solution:
A kind of reflective solder strip improving welding pulling capacity, including the welding body in zigzag structure, described welding is interconnected by two sections and the main gate line linkage section and the back electrode linkage section that are connected with cell piece main gate line and back electrode respectively are constituted；Described main gate line linkage section surface configuration has concavo-convex reflective structure, and described back electrode linkage section surface is smooth flat structure.
Described main gate line linkage section is identical with cell piece grid line width, and back electrode linkage section is identical with back electrode width.
Described concavo-convex reflective structure is laciniation.
The space width of described laciniation is 150 μm.
The addendum angle of described laciniation is 120 °.
A kind of photovoltaic module, including the safety glass being from top to bottom cascading, the first EVA layer, single crystal battery chip arrays, the second EVA layer and back-panel glass；The described adjacent cell piece in single crystal battery chip arrays forms array by described reflective solder strip series connection；Wherein, surface configuration has the main gate line linkage section of concavo-convex reflective structure to weld with the main gate line of cell piece；Surface is that the back electrode linkage section of smooth flat structure welds with the back electrode of cell piece.
Compared with prior art, this utility model has the advantages that
A kind of reflective solder strip improving welding pulling capacity of this utility model, by changing the surface texture of calendering roller bearing, is designed as welding half and has reflective structure, and half does not has reflective structure.So, there is the part of reflective structure to be welded on battery front side electrode, still there is reflective structure.And not having the part welding of reflective structure to be welded on cell backside, so welding pulling capacity is improved.Technical problem to be solved in the utility model is to provide a kind of reflective solder strip improving welding pulling capacity, and this reflective solder strip compares the reflective solder strip that on market, main flow uses can improve welding pulling capacity, does not affect component power output performance simultaneously.
This utility model one photovoltaic module, uses the reflective solder strip series cells improving welding pulling capacity to form set of cells, and on welding, matallic surface layer is with concavo-convex reflective structure, i.e. light secondary can be utilized, reflex to battery surface, play sunken photo effect, improve the power output of assembly.

[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is described further:
As it is shown in figure 1, a kind of reflective solder strip improving welding pulling capacity of this utility model, including the welding 6 in zigzag structure, this structure can be effectively improved welding pulling capacity, promotes assembly yield rate and performance；Described welding 6 is interconnected by two sections and the main gate line linkage section 61 and the back electrode linkage section 63 that are connected with cell piece main gate line and back electrode respectively are constituted；Described main gate line linkage section 2 is identical with cell piece grid line width, and back electrode linkage section 3 is identical with back electrode width, it is possible to effectively reduce the resistance of welding itself.
Of the present utility model being improved by, main gate line linkage section 61 has concavo-convex reflective structure, and back electrode linkage section 63 does not has reflective structure；This reflective solder strip can improve welding pulling capacity, does not affect component power output performance simultaneously.
As in figure 2 it is shown, actually used time structure be: a kind of photovoltaic module installing above-mentioned reflective solder strip, including safety glass the 1, first EVA layer 2 being from top to bottom cascading, single crystal battery chip arrays the 3, second EVA layer 4 and back-panel glass 5；The array that adjacent cell piece in single crystal battery chip arrays 3 is formed by welding 6.Wherein, main gate line linkage section 61 has reflective structure, welds with the main gate line of cell piece；Back electrode linkage section 63 does not has reflective structure, welds with the back electrode of cell piece.
Principle of the present utility model is as follows:
As in figure 2 it is shown, by welding 6 by the front electrode of first battery and the backplate of second battery, make circuit obtain through.On welding, matallic surface layer is with concavo-convex reflective structure, as it is shown on figure 3, i.e. can be utilized by light secondary, reflexes to battery 3 surface, plays sunken photo effect, improves the power output of assembly.But concave-convex surface reflective structure is unfavorable for welding of welding and battery aluminum back surface field, and back electrode linkage section 63 does not has reflective structure.Solve the problem that welding pulling capacity reduces, the most do not affect the long-term reliability of assembly.
