Abstract
The invention relates to a structure of a solar battery module. The structure of the solar battery module comprises a back panel positioned at the bottom, wherein a lower ethylene-vinyl acetate copolymer (EVA) layer is positioned above the back panel; a battery string layer is positioned above the lower EVA layer; an upper EVA layer is positioned above the battery string layer; a toughened glass layer is positioned above the upper EVA layer; the battering string layer comprises at least two battery strings arranged adjacently; and a connecting body is in lap joint with a junction of the obverse sides or the reverse sides of the adjacent battery strings. The invention provides a production process of the solar battery module. In the process of transferring and laminating stacked modules, the battery strings are difficult to displace and the adjacent battery strings are not extruded with each other, so that the structure of the solar battery module cannot be scrapped.
Description
Technical field
The present invention relates to energy technology field, be specifically related to a kind of structure of solar module.
Background technology
Solar module is to utilize photovoltaic effect and solar energy is converted into the device of electric energy, can produce photogenerated current when solar irradiation is mapped to surfaces of cell.The structure of present employed solar module comprises the backboard that is positioned at the bottom, the top of backboard is following EVA layer, following EVA layer top is the battery strings layer, battery strings layer top is last EVA layer, last EVA layer top is the toughened glass layer, and described battery strings layer comprises the battery strings of at least two adjacent arrangements.The production process of solar module comprises the face of weld, weldering battery strings of battery sheet, stacked, step such as lamination encapsulates, frame up.In stacked operation, elder generation's placing toughened glass, then at toughened glass upper berth one deck EVA, then will weld good battery strings and be tiled on the EVA, connecting circuit repaves one deck EVA on battery strings, last layer overlay backboard, after laying is finished, fix with high temperature gummed tape, be sent to laminating machine then and carry out the lamination encapsulation at periphery.The shortcoming of the solar module of said structure is: in the production process of solar module, in with stacked good assembly transfer and lamination process, displacement appears in battery strings easily, even between the adjacent battery strings extruding can appear, thereby cause assembly to scrap, this problem causes very big loss to production.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of in the production process of solar module, in with stacked good assembly transfer and lamination process, battery strings is not easy to occur displacement, and can not occur extruding between the adjacent battery strings, thereby can not cause the structure of the solar module that assembly scraps.
For addressing the above problem, the technical solution used in the present invention is: the structure of solar module, comprise the backboard that is positioned at the bottom, the top of backboard is following EVA layer, following EVA layer top is the battery strings layer, and battery strings layer top is last EVA layer, and last EVA layer top is the toughened glass layer, described battery strings layer comprises the battery strings of at least two adjacent arrangements, and the front of described adjacent cell string or the intersection of reverse side are overlapped with connector.
Described connector is the high temperature fixation adhesive tape.
The intersection of described adjacent cell string is respectively arranged with at least two connectors.
The invention has the beneficial effects as follows: the solar module of said structure, intersection at the adjacent cell string is provided with connector, make in the production process of solar module, in with stacked good assembly transfer and lamination process, battery strings is not easy to occur displacement, and can not occur extruding between the adjacent battery strings, thereby can not cause assembly to scrap, reduce production loss.
Description of drawings
Fig. 1 is the schematic diagram of the structure of solar module of the present invention;
Fig. 2 is the sectional structure schematic diagram of A-A direction among Fig. 1;
Among the figure: 1, backboard, 2, following EVA layer, 3, the battery strings layer, 4, go up the EVA layer, 5, the toughened glass layer, 6, the high temperature fixation adhesive tape.
Embodiment
Be described in further detail below by the structure of specific embodiment solar module of the present invention.
As shown in Figure 1 and Figure 2, the structure of solar module, comprise the backboard 1 that is positioned at the bottom, the top of backboard 1 is following EVA layer 2, following EVA layer 2 top are battery strings layer 3, and battery strings layer 3 top are last EVA layer 4, and last EVA layer 4 top are toughened glass layer 5, described battery strings layer 3 comprises the battery strings of several adjacent arrangements, and the intersection in the front of described adjacent cell string is overlapped with two high temperature fixation adhesive tapes 6.Perhaps also can be at two high temperature fixation adhesive tapes 6 of intersection overlap joint of the reverse side of adjacent cell string.
The invention has the beneficial effects as follows: the solar module of said structure, intersection at the adjacent cell string arranges high temperature fixation adhesive tape 6, described high temperature fixation adhesive tape 6 abilities 180 are spent high temperature and are not melted, and transparent nontoxic free from extraneous odour, anti-ageing, to solar module without any infringement, fixation by high temperature fixation adhesive tape 6 is so that achieve a fixed connection between the adjacent cell string, thereby whole battery strings layer 3 is connected as a single entity. In the production process of solar module, in stacked good assembly transfer and lamination process, battery strings is not easy displacement to occur, and can not occur extruding between the adjacent battery strings, thereby can not cause assembly to scrap, and has reduced production loss.
