Moreover, electric performance of the double-glass solar cell component is improved and simultaneously types of double-glass components are enriched, thereby providing more building integrated photovoltaic solutions to architects and enhancing beauty impression of the double-glass cell component which is used as a building material combined with buildings.
Description
Technical field
The utility model belongs to the double glazing solar module of double glazing solar module technical field, particularly a kind of anti-light pollution.
Background technology
At present, conventional double glazing solar module hereinafter to be referred as two glass assemblies, as shown in Figure 1, is made of ultra-white float glass header board 1, front resin clip glued membrane 2, photoelectricity part 3, back side resin clip glued membrane 4, float glass backboard 5 usually.Two glass assemblies have the direct light transmittance of certain visible light, satisfied the requirement of BIPV to a certain extent, can be used as building elements such as sunshade top, curtain wall, skylight, both saved the construction material cost, can be building power supply itself by opto-electronic conversion again.But because said structure adopts the refractive index of simple glass header board and air that certain difference is arranged, in glass, air interface the direct reflection of visible light can take place, such structure can produce dazzle when using as construction material, causes light pollution.And with regard to crystalline silicon double glazing assembly, because than the conventional solar cell assembly, lacked the white backboard with high emission, can not effectively utilize depth zero optically focused effect, the conventional assembly rated power that the same battery sheet of the rated power of two glass assemblies is arranged reduces about 3%～5%.
The utility model content
Technical problem to be solved in the utility model is: the double glazing solar module that designs a kind of anti-light pollution, improve the power output of two glass assemblies, light pollution phenomenon when reduction is used as glass curtain wall or building element, abundant two glass assemblies are as the decorative effect of construction material.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of double glazing solar module of anti-light pollution, comprise header board, photoelectricity part and backboard, build up integral body by the resin clip adhesive film between header board, photoelectricity part and the backboard, header board is an anti-reflective glass.
Anti-reflective glass is the plated film anti reflection glass.
Anti-reflective glass is the matte anti-reflective glass.
The beneficial effects of the utility model are: adopt the glass with anti-reflective effect or claim the header board of anti-reflective glass as two glass assemblies, normal preparation technology according to two glass assemblies, disposable processing, just power output about 2% that can lifting subassembly, and eliminate light pollution when using as much as possible as building elements such as glass curtain walls.This utility model can be enriched the classification of two glass assemblies when improving the product electrical property, for the architect provides more BIPV solution, strengthen when using as construction material and the aesthetic feeling that combines of building own.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1: the structure chart of conventional double glazing solar module;
Fig. 2: the double glazing solar cell assembly construction figure that adopts the coated glass header board;
Fig. 3: matte anti-reflective glass header board double glazing solar cell assembly construction figure;
Fig. 4: coated glass destructive interference antireflective schematic diagram;
Wherein: 1. ultra-white float glass header board, 2. front resin clip glued membrane, 3. photoelectricity part, 4. back side resin clip glued membrane, 5. backboard, 6. plated film ultra-white float glass header board, 7. matte ultrawhite anti-reflective glass header board, 8. float glass, 9. rete.
Embodiment
Shown in Fig. 2 and 3, a kind of double glazing solar module of anti-light pollution comprises header board, photoelectricity part 3 and backboard 5, builds up integral body by the resin clip adhesive film between header board, photoelectricity part 3 and the backboard 5, and header board is an anti-reflective glass.
Modular construction as shown in Figure 2.Principle as shown in Figure 4.In visible-range, mainly realize the high-quality antireflective on float glass surface by destructive interference.This interference effect is produced by the film system of single rete or multilayer film.With the monofilm is example, and in the wave-length coverage that requires, each rete in this film system all is that extinction coefficient k approaches 0 low absorptivity dielectric material and constitutes greater than 1 by refractive index n really.If light is perpendicular to surperficial incident, the amplitude condition that can produce anti-reflective effect of monofilm is n so
2=n
G, n is the true refractive index of antireflective coating; n
GBe the true refractive index of glass in visible wavelength range.Correspondingly, antireflecting phase condition is: nd=λ/4, and λ is a wavelength selected in visible-range; Nd is called as " optical thickness ".For wavelength selected, the rete that satisfied these conditions is inhibitory reflex fully just.
If float glass 8 outer surfaces are coated with the rete 9 of average 120～130nm thickness as SiO
2Layer, the rated power of assembly can promote about 2% than traditional double glass assembly.Plated film can be carried out by magnetron sputtering or sol-gal process in float glass 8 surfaces, effective wave band transmitance for crystal silicon cell sheet 320～1200nm improves 2%～3%, improved the effective rate of utilization of solar radiation, thereby make battery component have higher photoelectric conversion efficiency, be presented as higher rated power output on the macroscopic view.Because SiO
2Refractive index between glass and air, according to principle, sunlight is at air, SiO
2The reflection at interface descends, and sunlight is at air, SiO
2The interface, SiO
2, glass interface generation destructive interference, more sunlight sees through the photovoltaic effect that glass participates in the battery sheet.
The structural representation of combining structure such as Fig. 3.Matte ultrawhite anti-reflective glass header board 7 is different from ultra-white float glass, and glass can be by preparing with rolling process.Adopt special knurling rolls, by the hot mastication embossed technology, utilize the diffuse reflection principle of matte style, reduce the reflectivity of light greatly, it is had under various angle incident conditions all high sunlight transmitance.For two glass assemblies, use matte is anti-reflection two glass assemblies of ultra-clear glasses header board usually as building element, can effectively prevent light pollution, on the basis of improving assembly rated power about 1～2%, make the interior space obtain more sufficient sunlight irradiation, enriched the aesthetic effect of building.Be suitable for not requiring the occasion of directly viewing and admiring outdoor view.
