Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in FIG. 1 to 3, the reflective photovoltaic module of the present embodiment, comprise the photovoltaic glass 1 be laminated to successively from top to bottom in frame 8, ground floor packaging adhesive film 2, battery component 3, second layer packaging adhesive film 4 and packaging back board 5, the back side of packaging back board 5 is provided with terminal box 6, battery component 3 comprises battery strings and is located at many reflecting strips 34 of battery strings upper surface, and battery strings is made up of cell piece 31 and being joined end to end by the matrix welding 32 being separately positioned on adjacent cell sheet 31 upper surface and lower surface.The front end of the matrix welding 32 namely on the downside of cell piece 31 is connected to the rear end of the matrix welding 32 of cell piece upper surface above, by that analogy, until be connected to last cell piece 31, thus obtain a string battery strings, then reflecting strips 34 is pasted the upper surface being positioned at battery strings front matrix welding 32.
Every bar reflecting strips 34 is the uninterrupted structure of a whole piece in the present embodiment, has the concavo-convex reflective structure 36 arranged continuously at the upper surface of its reflecting strips 34.In order to improve reflective structure reflecting effect the utility model by reflective structure 36 for being set to zigzag.The length of this reflecting strips 34 and the length of battery strings match, and its width is 1.6 ~ 4.5mm.The material of ground floor packaging adhesive film 2 and second layer packaging adhesive film 4 can adopt EVA, PO, PVB or silica gel material, adopts EVA material in the present embodiment.
Fig. 4 is reflecting strips operation principle schematic diagram provided by the invention, as shown in Figure 4, when solar irradiation is mapped in reflecting strips 34, can be reflected to EVA interface and glass interface, and then is reflexed to cell piece 31 surface by EVA and glass interface.Reflective photovoltaic module of the present invention has following advantage, the light being irradiated to its surface reflects back by reflecting strips 34, and be finally converted to the incident light of cell piece 31, effectively increase the electron-hole pair of cell piece, thus make the power output of photovoltaic module increase by more than 1.5%.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that the utility model claims determine.
