Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
Shown in Fig. 1-2, a kind of double-sided solar battery assembly, comprise laminate 1 and module frame 2, laminate 1 is located in the module frame 2, laminate 1 is formed by glass 6, encapsulating material 7, cell piece, encapsulating material 7 and backboard successively lamination, and cell piece is the two-sided equal double-side cell sheet 8 that can generate electricity, and backboard is transparent back panel 9, module frame 2 comprises short frame 4 and long margin frame 5, is bonded with terminal box 3 on the transparent back panel 9.
For reducing the rear module frame of double-sided solar battery assembly installation and blocking by the shade of line box to back side battery, the material of module frame 2 and terminal box 3 is selected and structural design will be paid special attention to.The material of module frame 2 can be aluminium alloy or engineering plastics, frame height and frame C face width degree will be less than the conventional single face solar module of same specification, and the distance of frame absciss layer casting die cell piece is larger than the conventional single face solar module of same specification; The dimensions of terminal box is less than cell piece, and height will be lower than the used terminal box of conventional single face solar module of same specification, and for improving the heat radiation function of terminal box in the double-sided solar battery assembly array, terminal box can be used potting compound junction box.
As shown in Figure 3, the version of laminate 1 is glass 6/ encapsulating material 7/ double-side cell sheet 8/ encapsulating material 7/ transparent back panel, and glass 6 is that photovoltaic toughened glass, encapsulating material 7 are ethylene-vinyl acetate copolymer (EVA) or polyvinyl butyral resin (PVB).The processing mode of laminate 1 adopts conventional single face manufacture of solar cells laminating technology, i.e. the mode that vacuumizes hot curing commonly used.
Shown in Figure 4 and 5, double-side cell sheet 8 needs cell piece of vacancy under lead-out wire 15 when arranging, and remaining cell piece is linked to be battery strings with interconnector 14 welding, and two adjacent battery strings are again with busbar 10 welding Lian Qicheng.Avoid head two row's busbar overlap joint short circuits, the transparent isolating bar 11 of two row's busbar 10 usefulness of head separates, middle row's busbar below the transparent isolating bar, two ends one row's busbar above transparent isolating bar, transparent isolating bar 11 can not be run into anterior row's cell piece 8.A cell piece of vacancy replaces with product indicia card 12, the in the same size of the dimensions of product indicia card and profile and cell piece, and the position of arranging that the product indicia card is placed on corresponding cell piece gets final product.Below the product indicia card, place L-type busbar 13, interconnector 14 welding of first cell piece of an end of L-type busbar and rear, row's busbar welding has so just coupled together cell pieces all in the laminate 1 in the middle of the other end and the head.Then at four lead-out wires 15 of four busbars 10 welding, the other end of lead-out wire passes backboard and stretches in the terminal box 3.
As shown in Figure 6, product ID 17 sticks on an end of busbar 10 before the laminate lamination, product ID just facing to glass 6.
As shown in Figure 7, behind the laminate lamination, laminate is stuck in the draw-in groove of module frame, and with four corner braces 18 with four angles of short frame 4 and long margin frame 5 docking fixing tightly, frame and laminate just have been combined into Double-sided battery pack like this.
Shown in Fig. 5 and 8, two ends at short frame 4 namely are provided with cable hole 19 near the position of long margin frame, when the double-sided solar battery assembly is mounted to array, terminal box connecting line 16 is placed in the short frame 4, afterbody passes from cable hole 19, can avoid like this terminal box connecting line 16 to block the cell piece at the back side, can also utilization activity band pass cable hole 19 and osculum 20 is fixed connecting line 16.
In sum, the present invention is to provide a kind of double-sided solar battery component technology, the laminating technology of this battery component is the same with conventional single face solar module, outward appearance is approximate conventional single face solar module also, increased the product indicia card that can hold the more products parameter information, reduced the decline of the packaging efficiency that causes when the double-sided solar battery assembly junction box is installed on the battery top, has simple, aesthetic in appearance generous, the packaging efficiency advantages of higher of processing technology, so offer application for a patent for invention in accordance with the law; This paper is to be described in detail principle of the present invention and implementation method, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof, can embodiment and range of application be replaced and be modified not breaking away from this patent core concept for the personnel that are familiar with the technology.
