Abstract

The utility model discloses a photovoltaic battery assembly. The photovoltaic battery assembly comprises solar cells which are square sheet-shaped, arranged at intervals, and mutually connected electrically. The upper and lower surfaces of the solar cells are respectively provided with a toughened glass panel and a backboard. The solar cells, and the toughened glass panel and the backboard are sealed and connected by EVA adhesive films, and are bonded and fused into a whole after lamination. The photovoltaic battery assembly is characterized in that right angles of each solar cell are all provided with matched cross fixing blocks. According to the utility model, by arranging the cross fixing blocks at all the angles of the solar cells, the displacements of the cells are restricted; the phenomena of shifts and fragments of the cells during the appearance inspection, EL test operation transmission process, and lamination process after the assembly is laminated are prevented effectively; the quality and the overall beauty of the assembly are improved; the production cost is reduced; the popularization and the application of the assembly are facilitated; and the aforementioned technical scheme is suitable for all crystalline silicon assemblies.

Description

A kind of photovoltaic cell component
Technical field
The utility model relates to the photovoltaic cell component field, particularly a kind of photovoltaic cell component that prevents solar battery sheet displacement and fragment.
Technical background
Existing photovoltaic cell component comprises toughened glass panel, polyvinyl fluoride composite membrane TPT backboard or toughened glass backboard, two-layer EVA glued membrane (vinyl-vinyl acetate copolymer) and middle one deck solar battery sheet, to be some squares of arranging of interval be fixed between the two-layer EVA glued membrane in the mode of array solar battery sheet, because solar battery sheet lacks fixation means, assembly builds up rear in visual examination, the cell piece fragment often occurs in EL test step transport process and the lamination process, the phenomenon of displacement, cause the photovoltaic cell component produced not attractive in appearance, quality is low, has strengthened simultaneously production cost.
The utility model content
For the existing deficiency of prior art, the purpose of this utility model is to provide a kind of and prevents from effectively building up that solar battery sheet is shifted in rear transport process and the lamination process, the photovoltaic cell component of fragment, improve the quality of products and overall appearance, reduce production costs.
The purpose of this utility model is achieved by the following technical programs, a kind of photovoltaic cell component, comprise the solar battery sheet that square sheet interval arranges and mutually is electrically connected, the above and below of described solar battery sheet is respectively equipped with toughened glass panel and backboard, between solar battery sheet and face glass, the backboard by the glued membrane sealing and be connected, bonding combining together is characterized in that behind the lamination, and the place, right angle of each solar battery sheet is equipped with the cross fixed block that is mated.
The preferred ultrawhite woven design of described toughened glass panel toughened glass, described glued membrane is selected the EVA glued membrane, and described backboard is selected toughened glass, polyvinyl fluoride composite membrane TPT, polyethylene terephtalate or thermoplastic elastomer.
The utility model preferred version is, four right angles that are positioned at the cross fixed block at middle part cooperate with the right angle of four solar battery sheets respectively, two inboard right angles that are positioned at the cross fixed block on the limit cooperate with the right angle, the outside of adjacent two solar battery sheets, and a right angle that is positioned at the cross fixed block at four angles cooperates with an outer right angle of this place, angle solar battery sheet.
Described cross fixed block selects light transmittance more than 90%, fusion point to be higher than the transparent material of laminating temperature.
Beneficial effect: the utility model arranges the cross fixed block by each angle at solar battery sheet, limited the displacement of cell piece, prevent that effectively assembly from building up the afterwards phenomenon of cell piece generation displacement and fragment in visual examination, EL test step transport process and lamination process, quality and the overall appearance of product have been improved, reduced production cost, be beneficial to applying of product, be applicable to all crystal silicon components.
Description of drawings
Fig. 1 is the layer structural representation of the utility model photovoltaic module;
Fig. 2 is the floor plan schematic diagram of solar battery sheet and fixed block;
Among the figure: 1-toughened glass panel, 2-EVA glued membrane, 3-cell piece, 4-cross fixed block, 5-EVA glued membrane, 6-backboard.
Embodiment
As shown in Figure 1, a kind of photovoltaic cell component provided by the utility model, top-down layer structure comprises toughened glass panel 1, EVA glued membrane 2, solar battery sheet 3, EVA glued membrane 5 and backboard 6, between solar battery sheet 3 and face glass 1, the backboard 6 by EVA glued membrane 2,5 sealings and be connected, bonding combining together after certain temperature, pressure and vacuum condition laminated, toughened glass panel 1 preferred ultrawhite woven design toughened glass, light transmittance reaches more than 91%; Backboard 6 is selected toughened glass, polyvinyl fluoride composite membrane TPT, polyethylene terephtalate or thermoplastic elastomer, ageing-resistant, corrosion-resistant, UV resistant radiation.In conjunction with shown in Figure 2, solar battery sheet 3 is fixed between the two-layer EVA glued membrane after selecting the square sheet interval of 125 * 125mm or 156 * 156mm to arrange and be electrically connected, because electric current and the voltage of monolithic solar cell sheet are all very little, generally be they acquisition high voltages of connecting first, parallel connection obtains high electric current again, the place, right angle of each solar battery sheet is equipped with the cross fixed block 4 that is mated, cross fixed block 4 selects light transmittance more than 90%, fusion point is higher than transparent rubber or the transparent epoxy resin of component lamination temperature, guarantee that the cross fixed block has certain pliability and structural in lamination process, and do not affect the whole transformation efficiency of battery component, four right angles that are positioned at the cross fixed block at middle part cooperate with the right angle of four solar battery sheets respectively, two inboard right angles that are positioned at the cross fixed block on the limit cooperate with the right angle, the outside of adjacent two solar battery sheets, and a right angle that is positioned at four jiaos cross fixed block cooperates with an outer right angle of this place, angle solar battery sheet.
Above-described embodiment is as better embodiment of the present utility model; describe technical conceive of the present utility model and essential implementation in detail; be not to be that protection range of the present utility model is limited; all any simple modification and equivalent structure transformation or modifications of doing according to the utility model Spirit Essence all should be encompassed within the protection range of the present utility model.
