A kind of double-sided solar battery component
The present invention relates to a kind of solar module, more particularly, to a kind of double-sided solar battery component.
With the non-renewable energy resources such as oil, coal continuous exploitation and consume and the modern life in need of the people to the energy
Ask and be continuously increased, the regenerative resource such as solar energy, wind energy is gradually realized and utilizes.Solar energy is a kind of safe and reliable, economy
Material benefit and the green energy resource being readily available, with huge utilization space, wherein, solar energy generation technology is exactly that solar energy is promoted
With a key areas of popularization.
What at present industrialized solar energy generation technology was main takes the form of crystal silicon and non-crystal silicon solar cell.It is brilliant
Silicon solar cell is generally glass/encapsulating material/monocrystalline, polycrystalline, class single crystal battery piece/encapsulating material/backboard, the knot of glass
Configuration formula, common non-crystal silicon solar cell is generally thin-film solar cells, typically on substrate deposit PN or
P-i-N structures, it is also desirable to be packaged with encapsulating material.Now, crystal silicon and the battery used by amorphous silicon solar cell module
Piece it is common be all one side cell piece, the packaged type of employing is also one side encapsulation, it is impossible to using the back of the body of solar module
Solar power station and photovoltaic-architecture-integral are required for larger erection space, solar power station to need to take sky
Spacious surface area, photovoltaic-architecture-integral needs the area for taking building curtain wall or roof, and cannot all utilize the back side
Light.In order to reduce needs of the solar module to erection space, the comprehensive generating efficiency for improving solaode is two-sided
Solaode is a kind of good solution, will have and have a broad prospect of the use.

The mutual latticing of adjacent monocell piece is connected to busbar.
Described border component includes upper short frame, and described upper short frame is provided with cable hole, double-sided solar battery
The connecting line of rosette is passed through from cable hole during component composition array, it is to avoid shadow occlusion of the connecting line to back side battery.
Described glass is safety glass, and described encapsulating material is that ethylene-vinyl acetate copolymer or polyvinyl alcohol contract
Compared with prior art, the present invention by the cell piece of conventional solar cell component be changed to that two sides can generate electricity pair
Face cell piece, the battery component can be widely used in the field such as solar power station and photovoltaic-architecture-integral, and processing technique letter
Single, generous, packaging efficiency aesthetic in appearance is high.

Below in conjunction with the accompanying drawings the present invention is described in detail with specific embodiment.
As shown in Figure 1-2, a kind of double-sided solar battery component, including laminate 1 and module frame 2, laminate 1 is located at
In module frame 2, by glass 6, encapsulating material 7, cell piece, encapsulating material 7 and backboard, successively lamination is formed laminate 1, battery
Piece is the two-sided equal double-side cell piece 8 that can be generated electricity, and backboard is transparent back panel 9, and module frame 2 includes short frame 4 and long margin frame 5,
Rosette 3 is bonded with transparent back panel 9.
Module frame and the shadow occlusion by line box to back side battery, group after to reduce the installation of double-sided solar battery component
The material of part frame 2 and rosette 3 is selected and structure design will be paid special attention to.The material of module frame 2 can be aluminium alloy
Or engineering plastics, bezel height and frame C faces width will be less than the conventional one side solar module of same specification, frame absciss layer
The distance of casting die cell piece is larger than the conventional one side solar module of same specification；The dimensions of rosette is less than
Cell piece, the rosette that be highly less than used by the conventional one side solar module of same specification is to improve double-sided solar
The heat radiation function of rosette in cell array module, rosette can use potting compound junction box.
As shown in figure 3, the version of laminate 1 is that 6/ encapsulating material of glass, 7/ double-side cell piece, 8/ encapsulating material 7/ is saturating
Bright backboard, glass 6 is photovoltaic safety glass, encapsulating material 7 is ethylene-vinyl acetate copolymer (EVA) or polyvinyl alcohol contracting fourth
Urea formaldehyde (PVB).The processing mode of laminate 1 is using conventional one side manufacture of solar cells laminating technology, i.e., conventional taking out is true
The mode of empty heat cure.
As shown in Figures 4 and 5, double-side cell piece 8 needs one piece of battery of vacancy in arrangement in the underface of lead-out wire 15
Piece, remaining cell piece welding of mutual latticing 14 is linked to be battery strings, and two adjacent battery strings weld Lian Qicheng with busbar 10 again.
The overlap joint short circuit of the row's busbar of head two, two row's busbars 10 of head is avoided to be separated with transparent isolation bar 11, a middle row is confluxed
Bar is below transparent isolation bar, the row's busbar of two ends one above transparent isolation bar, transparent isolation bar 11 can not encounter anterior one
Row's cell piece 8.One piece of cell piece product indicia card 12 of vacancy replaces, the dimensions and profile of product indicia card and battery
Piece it is in the same size, by product indicia card be placed on correspondence cell piece arrangement position.L is placed in the lower section of product indicia card
Type busbar 13, the mutual latticing 14 of first piece of cell piece in one end and rear of L-type busbar is welded, one in the middle of the other end and head
Row's busbar welding, thus couples together all of cell piece in laminate 1.Then weld on four busbars 10
Four lead-out wires 15, the other end of lead-out wire passes backboard and stretches into 3 in rosette.
As shown in fig. 6, product ID 17 is pasted onto one end of busbar 10 before laminate lamination, product ID
Just facing to glass 6.
As shown in fig. 7, after part to be laminated lamination, laminate is stuck in the draw-in groove of module frame, and with four corner braces 18
Four angles that short frame 4 and long margin frame 5 are docked fixing tightly, such frame and laminate have just been combined into double-side cell
As shown in figs. 5 and 8, namely cable hole 19 is provided near the position of long margin frame at the two ends of short frame 4, when two-sided
When solar module is mounted to array, rosette connecting line 16 is placed in short frame 4, and afterbody is passed through from cable hole 19,
Rosette connecting line 16 can be so avoided to block the cell piece at the back side, can also be using movable band through cable hole 19 and row
Connecting line 16 is fixed in water hole 20.
In sum, the present invention is to provide a kind of double-sided solar battery component technology, the lamination work of the battery component
Skill as conventional one side solar module, outward appearance also approximate routine one side solar module, increased to accommodate
The product indicia card of more products parameter information, reduces when double-sided solar battery assembly junction box is installed on battery top and makes
Into packaging efficiency decline, have the advantages that processing technique is simple, generous, packaging efficiency aesthetic in appearance is high, then carry in accordance with the law
In application for a patent for invention；It is described in detail with the principle and implementation to the present invention herein, the embodiment of the above
Illustrate that being only intended to help understands the method for the present invention and its core concept, for person familiar with this technology can not take off
In this patent core concept specific embodiment and range of application are replaced and are modified.
