Compared to prior art, the utility model solar module is arranged to transparent film layer by the first rete backboard and lower floor's glued membrane bonded, with black adhesive layer, the first rete and basic unit are bonded again, thus again reflect again after making sunray be entered the transparent film layer of backboard, and finally reflex to the surface of the cell piece of solar module, improve the conversion efficiency of cell piece.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that sunray is radiated at the backboard of the conventional solar module of prior art.
Fig. 2 is the structural representation of the utility model solar module, and on figure, illustrate the reflection path of light through backboard first rete.
Fig. 3 is the structural representation that the backboard of the utility model solar module accepts when sunray irradiates.
Embodiment
Shown in please refer to the drawing 2, the utility model discloses a kind of solar module 200, and described solar module 200 comprises glassy layer 4, upper strata glued membrane 51, cell piece 6, lower floor's glued membrane 52 and backboard 100 from top to bottom.The material of described upper strata glued membrane 51, lower floor's glued membrane 52 is EVA, at high temperature has certain mobility.
Shown in please refer to the drawing 2 to Fig. 3, described backboard 100 comprises the first rete 1, second rete 2 of contacting with lower floor glued membrane 52 and the basic unit 3 between the first rete 1, second rete 2.Described first rete 1, to be bonded together respectively by an adhesive layer between described second rete 2 and described basic unit 3.Described first rete 1 is for being positioned at the transparent film layer of described backboard 100 sensitive surface 101 side, and the adhesive layer on the downside of described first rete 1 and between described basic unit 3 is black adhesive layer 12.Described second rete 2 is for being positioned at the black fluorine rete on described sensitive surface 101 opposite, and the adhesive layer between described black fluorine rete and described basic unit 3 is colourless adhesive layer 22.
Described basic unit 3 is pet layer.Described transparent film layer 1 is fluorine material layer.Described transparent film layer is generally PE (polyethylene), and material is softer.Described black adhesive layer 12 is black glue layer.Described colourless adhesive layer 22 is colorless glue layer.Described black glue layer is compared with described colorless glue layer, just inside colorless glue layer, add black carbon black to form black glue layer, the main component of described carbon black is carbon, simultaneously containing elements such as a small amount of hydrogen, oxygen, nitrogen, these oligo-elements mainly exist with forms such as hydroxyl, carbonyl, amino or cyano group, and wherein the normal contents of carbon black is 1% ~ 2%.
When the utility model solar module 200 is encapsulated lamination, the sensitive surface 101 of described backboard 100 is combined with described lower floor glued membrane 52 lamination, because the material of described lower floor glued membrane 52 is EVA, at high temperature there is certain mobility, now described first rete 1(and transparent film layer) combine with described lower floor glued membrane 52, because transparent film layer 1 is transparent, even if so the transparent film layer 1 after lamination overflows on glue to described cell piece 6, also can not impact cell piece 6 pairs of light conversions, also can not impact the outward appearance of solar module 200 simultaneously.
Compared to prior art, the utility model solar module 200 is set to transparent by first rete 1 that will contact with EVA (namely lower floor's glued membrane 52), when solar module 200 lamination, even if there is the phenomenon of glue to solar battery sheet 6 surface of overflowing in the first rete 1, because it is transparent, the outward appearance of solar module 200 totally also can not be affected.While the first rete 1 of described backboard 100 is arranged to transparent film layer 1, described transparent film layer 1 bonds with described basic unit 3 by recycling black adhesive layer 12, the surface of cell piece 6 is reflexed to again after making light enter the transparent film layer 1 of described backboard 100, improve the conversion efficiency of cell piece 6, generally, general black backboard reflectivity is 2.5%, and backboard 100 reflectivity of the utility model solar module 200 is 42.5%.
In addition, although this specification has been described in detail the utility model with reference to the above embodiments, but, those of ordinary skill in the art is to be understood that, person of ordinary skill in the field still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in right of the present utility model.
