Combination, the big medium-sized power station to gigawatt, the little solar battery group to only for a family, this is that other power supplys are incomparable
's.
Solaode generally comprises multiple cell pieces, and the connection between cell piece relies on reflective solder strip, reflective solder strip to send out
The conductive important function for gathering electricity is waved, the quality of reflective solder strip quality will directly affect the light source utilization rate of solaode, at present
Domestic reflective solder strip, is directly coated tin-lead solder, is carried out using solder reflective substantially after copper-based surfaces rag.It is this kind of reflective
Welding, in welding as solder layer is heated thawing, it is difficult to keep original form, causes reflector layer morphologic change, reflective effect
Fruit reduces, and reflective solder strip is when with welding of battery film, it is difficult to form effective solder layer, it is necessary to additionally increase solder, more fiber crops
It is tired.
Utility model content
The purpose of this utility model is the defect for overcoming prior art to exist, there is provided a kind of reflecting effect is good, can be abundant
Using the efficient precoating stannum reflective solder strip of light source.
This utility model solves the technical scheme adopted by its technical problem：A kind of efficiently precoating stannum reflective solder strip, bag
Bar tabular Copper base material is included, the one or both sides outer plate surface in Copper base material is serrated, in the outer plate surface being serrated in Copper base material
Coating reflector layer, the both sides of Copper base material are respectively arranged solder layer and solder layer spacing arrangement on the length direction of Copper base material, weldering
The bed of material is coated in the outer surface of reflector layer or is coated in the outer plate surface of Copper base material, and the fusing point of reflector layer is molten higher than solder layer
Point.
Beneficial effect：Fusing point of the fusing point of the independent reflector layer in the present invention higher than solder layer, the reflector layer meeting in welding
Initial configuration is kept, good reflecting effect after welding, is still had, incident sunlight effectively can be reflexed to glass table by reflector layer
Face, then carry out total internal reflection, the whole light that almost can be irradiated to effectively utilizes on welding, effective compensation cell piece are welded
The daylighting area that band is blocked, can make full use of light source.
Description of the drawings
Fig. 1 is reflective section when this utility model one side is reflective of schematic cross-section；
Fig. 2 is welding section schematic cross-section when this utility model one side is reflective；
Fig. 3 is sectional view when this utility model is two-sided reflective.
In figure：10- Copper base materials；20- reflector layers；30- solder layers.
Specific embodiment
With reference to Fig. 1-Fig. 3, the utility model will be further described.
A kind of efficiently precoating stannum reflective solder strip, including bar tabular Copper base material 10, the one or both sides outside plate in Copper base material 10
Face is serrated, and coats reflector layer 20 in Copper base material 10 in the outer plate surface being serrated, and the both sides of Copper base material 10 are respectively arranged weldering
The bed of material 30 and solder layer 30 spacing arrangement on the length direction of Copper base material 10, solder layer 30 are coated in the outer surface of reflector layer 20
Or it is coated in the outer plate surface of Copper base material 10, the fusing point of the fusing point of reflector layer 20 higher than solder layer 30.
The present invention designs an independent reflector layer 20, and reflective lines is zigzag, accurate regular, light compensation
Function is preferable, and the design of reflective lines is maximally utilized as direction with Light Source Compensation and light source, sets about changing existing solar energy
Electric light source compensation problem, rationally fully maximally utilizes light source, increase solar power generation cell piece intensity of illumination and area, and which is right
2% to 3% can be improved in the power of whole component, better than the 1% of conventional road welding.In addition, solder layer 30 is independent interruption
Property exist, the present invention adopt independent reflector layer 20 fusing point higher than solder layer 30 fusing point, welding when 20 meeting of reflector layer
Initial configuration is kept, good reflecting effect after welding, is still had, incident sunlight effectively can be reflexed to glass by reflector layer 20
Surface, then carry out total internal reflection, the whole light that almost can be irradiated to effectively utilizes on welding, effective compensation cell piece quilt
The daylighting area that welding is blocked, and without the need for additionally adding solder when welding, it is more convenient.When the side outer plate surface of Copper base material 10 is applied
When covering reflector layer 20, with the reflective effect of one side；When the both sides outer plate surface of Copper base material 10 is coated with reflector layer 20, with double
The reflective effect in face, compatible various blowing modes, even more suitable for domestic various welding types.When specifically used, because reflective
Welding is connection cell piece both positive and negative polarity, therefore a reflective solder strip part is welded on cell piece front, and a part is welded in battery
The piece back side.Positive part is welded in, the upper surface of reflective solder strip must be reflector layer 20, and weld part overleaf, reflective
The upper surface of welding is exactly solder layer 30.
As further preferred version：The section of each tooth of the sawtooth of the outer plate surface of the Copper base material 10 is isosceles three
It is angular, wherein, the scope of the long a of waist is 20um-100um, and the scope of apex angle ss is 90 ° -140 °, between the summit of adjacent teeth away from
It is 50um-200um from the scope of b.
Further, the reflector layer 20 is made up of the alloy of silver, aluminum, stannum, nickel metal material or above-mentioned material, described
Solder layer 30 is tin-lead solder, and the thickness range of solder layer 30 is 10-30um, and so, existing welding equipment completely can be straight
Deliver a child product, scrap build is required low, certainly, the material of reflector layer 20 is not limited to that this is several, as long as rationally.
Through test, the reflecting effect when apex angle ss is 120 ° is best.
It should be appreciated that specific embodiment described above is only used for explaining this utility model, it is not used to limit this reality
With new.By spirit of the present utility model it is extended obvious change or change still in protection of the present utility model
Among scope.
