Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in detail with specific embodiment.
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 Component.
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.
