Description
One, technical field
The invention belongs to the new forms of energy field of photovoltaic power generation, particularly solar module of a kind of alternative roof sheet tile and preparation method thereof.
Two, background technology
Prior art: because global energy crisis and environmental problem is increasingly serious; people are more and more urgent to the demand of new forms of energy and pollution-free regenerative resource, and solar energy power generating is rising in a new and renewable sources of energy technical field.
The primary element of solar energy power generating is the solar battery cell sheet, and monocrystalline silicon, polysilicon, amorphous silicon and hull cell etc. are arranged.The solar panel of being made up of one or more solar battery sheets is called photovoltaic module, or solar module, solar module be a kind of be the device of electric energy with conversion of solar energy, have that installation form is various, safety non-pollution, inexhaustible advantage, so obtained development energetically.
Current, the application of solar cell has entered departments such as industry, commerce, agricultural, communication, household electrical appliance and public utility from military field, space industry, especially can be dispersedly in the outlying district, high mountain, desert, island and rural area use, to save the very expensive transmission line of cost.But at this stage, its cost is also very high, and sending the 1kW electricity needs up to ten thousand dollars of investment, and therefore extensive use still is subjected to restriction economically.But; in the long run; invention along with the improvement of solar cell manufacturing technology and new light-electrical switching device; various countries are to the protection of environment with to the great demand of regeneration clean energy resource; solar cell will be to utilize the more practicable method of solar radiant energy, can be to utilize solar energy to open vast vistas on a large scale human future.
TPT material (polyvinyl fluoride composite membrane) is the material that is used for the solar module encapsulation; three-decker is generally arranged: outer protective layer PVF has good anti-environmental attack ability; the intermediate layer is that mylar has the good insulation performance performance, and internal layer PVF needs to have good adhesive property through surface treatment and EVA.Common solar module all adopts white TPT material as backboard at present, and this has caused the shaded effect of existing solar module scarcely desirable.
Three, summary of the invention
Technical problem:
The present invention is directed to above-mentioned technological deficiency, a kind of solar module of shaded effect, alternative roof sheet tile preferably that has is provided.
Technical scheme:
Technical solution of the present invention is:
A kind of solar module of alternative roof sheet tile, by top layer, last ethylene-vinyl acetate copolymer layer, solar cell layer, following ethylene-vinyl acetate copolymer layer and backsheet layer, stack gradually from top to bottom and arrange, encapsulation constitutes, described top layer is a black polyvinyl fluoride composite membrane, and backsheet layer is the low iron toughened glass of high strength.
A kind of method for preparing the solar module of above-mentioned alternative roof sheet tile, step is: under 25 ℃ of room temperatures, the low iron toughened glass of high strength is put on the workbench tiling one deck ethylene-vinyl acetate copolymer on it; The good solar battery sheet of tiling string on above-mentioned ethylene-vinyl acetate copolymer; One deck ethylene-vinyl acetate copolymer that tiles again on above-mentioned solar battery sheet lays one deck black polyvinyl fluoride composite membrane then, puts laminating machine laminating at last into and solidifies, and obtains the solar module of alternative roof sheet tile.
Wherein, the low iron toughened glass of described high strength is high printing opacity matte toughened glass or high printing opacity plain bar glass.
Beneficial effect:
The present invention is directed to conventional solar cells assembly backboard is white TPT material, and the problem that shaded effect is bad provides that a kind of light-proofness is good, the solar module of alternative roof sheet tile.
The solar module of alternative roof sheet tile of the present invention adopts the low iron toughened glass of high strength, the EVA glued membrane that anti-aging degree is high, and backboard adopts black TPT material simultaneously, has obtained following remarkable result:
1, because the TPT material of black has been adopted on the top layer of this solar module, possesses good shaded effect, can be used for the roof and replace tile.
2, the backboard of solar module of the present invention has adopted high printing opacity matte toughened glass or high printing opacity plain bar glass packaging, and very high light transmittance is arranged, and can improve the photovoltaic module conversion efficiency.
3, have good hail suppression, can under various complicated harsh climate conditions, use.
Four, description of drawings
Fig. 1 is the three-dimensional exploded view of the solar module of alternative roof sheet tile of the present invention.
Among the figure, the 1-top layer; The last ethylene-vinyl acetate copolymer layer of 2-; The 3-solar cell layer; Ethylene-vinyl acetate copolymer layer under the 4-; The 5-backsheet layer.
Five, embodiment
Embodiment 1:
A kind of solar module of alternative roof sheet tile, by top layer 1, last ethylene-vinyl acetate copolymer layer 2, solar cell layer 3, following ethylene-vinyl acetate copolymer layer 4 and backsheet layer 5, stack gradually from top to bottom and arrange, encapsulation constitutes, described top layer 1 is a black polyvinyl fluoride composite membrane, and backsheet layer 5 is the low iron toughened glass of high strength.
The method for preparing the solar module of above-mentioned alternative roof sheet tile, step is: under 25 ℃ of room temperatures, the low iron toughened glass of high strength is put on the workbench tiling one deck ethylene-vinyl acetate copolymer on it; The good solar battery sheet of tiling string on above-mentioned ethylene-vinyl acetate copolymer; One deck ethylene-vinyl acetate copolymer that tiles again on above-mentioned solar battery sheet lays one deck black polyvinyl fluoride composite membrane then, puts laminating machine laminating at last into and solidifies, and obtains the solar module of alternative roof sheet tile.
Wherein, the low iron toughened glass of described high strength is high printing opacity matte toughened glass or high printing opacity plain bar glass.
