Description
Technical field
The present invention relates to field of photovoltaic power generation more particularly to a kind of photovoltaic welding belts and photovoltaic module.
Background technology
Photovoltaic module needs that battery is together in series as welding using tin plating Copper base material in the production process, the selection of welding
On need to consider its electrical and optical matching, general welding is using conventional Copper base material and in outer electroplating surfaces with tin metal
Layer, i.e., the leypewter layer of one layer of micron level thickness of immersion plating or plating, the making of this welding on the copper strips of certain size
It is simple for process, but the light-receiving area of a part of cell piece can be blocked after the welding of this welding, influence the output work of photovoltaic module
Rate.
With the sustainable development of photovoltaic industry, the requirement to photovoltaic module power is higher and higher, and improving power means to drop
Low component cost, thus occur many new materials on assembly material, component power is improved in terms of optically and electrically two,
Wherein, reflective solder strip is recently more popular, and the power of component can be improved from optics aspect, and current existing reflective solder strip is main
It is to attach one layer of reflective membrane on surface, realizes that light reflects by reflective membrane, the surface of reflective membrane is distributed with largely irregularly
Miniature concaveconvex structure, but experiment test shows that the light utilization of this reflective solder strip is still to be improved, and reflective membrane needs
Operation is bonded, it is also cumbersome.
Invention content
In view of this, the present invention provides a kind of photovoltaic welding belt and photovoltaic module, and to improve reflecting effect, lifting assembly is imitated
Rate.
Specifically, the present invention is achieved through the following technical solutions：A kind of reflective solder strip is provided, equipped with strip matrix
And the protrusion of body upper surface is formed in, the protrusion is through prolonging molded and being in pyramid, and protrusion has square bottom
And four inclined surface, tin layers are coated on the inclined surface.
Further, the length of side of the square bottom is 0.2-1mm, and four inclined surface are relative to described matrix
The angle of upper surface is 30-80 °, and the inclined surface is equilateral triangle.
Further, the thickness of the tin layers is 5-10 μm.
Further, the pyramid protrusion is uniformly distributed in the upper surface of described matrix.
What the present invention was also achieved through the following technical solutions：A kind of photovoltaic module is provided, which is included such as preceding institute
The reflective solder strip stated.
The present invention on welding surface by setting special pyramid structure that will be incident on the light on welding through secondary counter
It is mapped on cell piece, to improve the efficiency of light utilization and component.

Specific embodiment
Here exemplary embodiment will be illustrated in detail, example is illustrated in the accompanying drawings.Following description is related to
During attached drawing, unless otherwise indicated, the same numbers in different attached drawings represent the same or similar element.Following exemplary embodiment
Described in embodiment do not represent and the consistent all embodiments of the present invention.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects being described in detail in claims, of the invention.
It is only merely for the purpose of description specific embodiment in terminology used in the present invention, is not intended to limit the invention.
It is also intended in the present invention and " one kind " of singulative used in the attached claims, " described " and "the" including majority
Form, unless context clearly shows that other meanings.It is also understood that term "and/or" used herein refers to and wraps
Containing one or more associated list items purposes, any or all may be combined.
As shown in Figures 1 and 2, the present invention discloses a kind of reflective solder strip 100, is equipped with strip matrix 10 and is formed in base
The protrusion 20 of 10 upper surface of body, wherein, the upper surface of described matrix 10 is light-receiving surface, and the protrusion 20 is in pyramid,
Bottom and four inclined surface 30 equipped with square, the length of side of the square bottom are 0.2-1mm, four inclined surface 30
Angle A relative to the upper surface of described matrix 10 is 30-80 °, and the inclined surface 30 is equilateral triangle.
The surface (i.e. described four inclined surface 30) of the pyramid protrusion 20 is coated with tin layers, and the thickness of tin layers is excellent
Select 5-10 μm.Moreover, pyramid protrusion 20 is uniformly distributed in the upper surface of described matrix 10.
The pyramid protrusion 20 takes shape in the upper surface of described matrix 10, and pyramid protrusion by calendering technology
20 are structure as a whole with described matrix 10, the patch reflective membrane mode in non-existing technology, and the molding of pyramid protrusion 20 uses
Calendering mode is more simple.
The pyramid structure can be further utilized with this by the light reflection to cell piece being incident on welding 100
Secondary reflection light.Described matrix 10 will make, and control pyramid knot after calendering according to normal 100 manufacturing process of welding
Tinning layer thickness on structure, prevent welding 100 in high-temperature soldering because tin layers melting cause it is recessed between adjacent pyramid structure
Tin is inserted in place, so as to influence reflectivity.In addition, four inclined surface 30 of the pyramid structure can be with reflection light, when too
When sunlight height of incidence, angle difference, the light utilization of photovoltaic module of the present invention can be than existing photovoltaic module higher.
Experiments have shown that in table as shown in Figure 3, for using the photovoltaic module of conventional road welding, identical
Setting angle under, photovoltaic module described in the embodiment of the present invention have higher incident angle modifier (IAM, Incidence
Angle modifier), so-called incident angle modifier is used to represent sunray non-normal incidence and difference during vertical incidence
Different, more preferably (i.e. IAM is bigger, then it represents that during sunlight incidence to the adjustment of incident ray and correction effect for photovoltaic module of the present invention
Angle influences smaller), ideal reflecting effect is can reach, improves the utilization rate of light, the reflective solder strip 100 can not only
Component power is improved from optically and electrically upper, and component will not influence the power generation of component in use due to incident angle difference outdoors
Amount.
The present invention also provides a kind of photovoltaic module, the photovoltaic module uses above-mentioned reflective solder strip 100, no longer superfluous herein
It states.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God and any modification, equivalent substitution, improvement and etc. within principle, done, should be included within the scope of protection of the invention.
