Description
Technical field
The utility model relates to a kind of double glazing solar module, relates in particular to a kind of double glazing solar module with high reflectance back board structure.
Background technology
At present, conventional double glazing solar module is made of glass front plate, resin clip glued membrane, photoelectricity part, resin clip glued membrane, simple glass backboard usually.The double glazing solar module of this traditional structure has the direct light transmittance of certain visible light, satisfy the requirement of BIPV to a certain extent, can be used as building elements such as sunshade top, curtain wall, skylight, both having saved the construction material cost, can be building power supply itself by opto-electronic conversion again.But, the back veneer material of said structure surpasses 85% glass material because being visible light wave range, near infrared band transmitance, this just means that the overwhelming majority in the electromagnetic wave of visible light and near infrared band can freely see through the white space outside the photoelectricity part, thereby has reduced the effective rate of utilization of solar irradiation.According to depth zero optically focused effect, backboard with highly reflective, help to shine in the assembly sunlight between the battery by the backboard scattering and by the working region of sensitive surface glass-reflected to assembly, and the electromagnetic wave of part near infrared band sees through the photoelectricity part that still can be emitted to assembly behind the battery sheet, thus the output that improves solar module.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of power output high double glazing solar module, can adjust the direct light transmittance of product, can enrich the decorative effect of double glazing solar module as construction material again.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of double glazing solar module with high reflectance back board structure, stackedly arranged, encapsulated and constitute by glass front plate, ground floor resin clip glued membrane, photoelectricity part, second layer resin clip glued membrane, glass back plate from front to back, described glass back plate is a kind of high reflecting glass backboard.
Further, in order to improve the glass back plate reflectivity, the high reflecting glass backboard is formed by glass with the polymeric matrix reflectance coating of fitting in its surface; Or form by glass with metallic matrix reflectance coating of fitting in its surface; Can also and be plated in its surperficial metallic matrix reverberation coatings by glass forms.
Further, the polymeric matrix reflectance coating is the PET reflectance coating; The metallic matrix reflectance coating is an aluminium foil; Metallic matrix reverberation coatings is Ag film or Al film.
Further, because that float glass has is pure, transparency good, good cutting, advantage such as cracky not, so glass is float glass.
The beneficial effects of the utility model are: polymeric matrix reflectance coating or metallic matrix reflectance coating are set at the glass back plate back side, can effectively improve the utilance of light, the power output of double glazing solar module is significantly improved.This utility model can also be enriched the classification of double glazing solar module when improving the product electrical property, the solution of more BIPV is provided for building trade.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the double glazing solar module with high reflectance back board structure of first kind of execution mode of the present utility model;
Fig. 2 is the structural representation of the double glazing solar module with high reflectance back board structure of second, third kind execution mode of the present utility model.
Wherein: 1, glass front plate; 2, ground floor resin clip glued membrane; 3, photoelectricity part; 4, second layer resin clip glued membrane; 5, glass; 5-1, coated glass backboard; 5-2, polymeric matrix reflectance coating or metallic matrix reflectance coating.
Embodiment
A kind of double glazing solar module with high reflectance back board structure is stackedly arranged, is encapsulated and constitute by glass front plate 1, ground floor resin clip glued membrane 2, photoelectricity part 3, second layer resin clip glued membrane 4, glass back plate from front to back; Glass back plate is a kind of high reflecting glass backboard, and it is formed by glass 5 with the polymeric matrix reflectance coating of fitting in its surface; Also can form by glass 5 with the metallic matrix reflectance coating of fitting in its surface; Can also and be plated in its surperficial metallic matrix reverberation coatings by glass 5 forms.
Execution mode one:
As shown in Figure 1, common float glass becomes coated glass backboard 5-1 through online magnetron sputtering membrane process plating Ag film or Al rete, substantially the single face that reaches light sees through effect, promptly the outdoor sunlight in effective wave band of 320～1200nm is reflected back toward the battery sheet by coated glass backboard 5-1 the time, this coated glass backboard 5-1 single face reflectivity reaches 60%～85%, the conventional double glazing solar module of the rated power of this double glazing solar module improves 2%～4%, 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 the zone of most assemblies is occupied by photoelectricity part 3, there is not the risk of light pollution in whole assembly.Aspect building decorative effect, this assembly has the better shaded effects of more conventional double glazing solar module and can guarantee to have protected indoor privacy on the indoor basis that certain daylighting degree arranged; From outdoor, do not discharge the similar chamber glass of inquiring of white space of battery, outdoorly under the high irradiance situation also almost can not see indoor view.
Execution mode two:
As shown in Figure 2, glass 5 is common float glass, the polymeric matrix reflectance coating is base material with PET, with low cost, normally with film base material by mass coloration, vacuum evaporating, ultra-violet absorber inject, reflection-type energy-saving film that technical process forms such as anti-scratch layer and multilayer are synthetic, the reflectivity of whole film can reach more than 80%, and can regulate the rete reflectivity by the technology controlling and process of system film.It is on glass that these films can be used for automobile decoration, also can be used on the ornament materials of building.After the preparation of double glazing solar module is finished, by professional film coating process, can get rid of the gas between float glass and the highly reflective polymeric matrix reflectance coating, the rete close attachment is in the outer surface of float glass.The more conventional double glazing solar module of the rated power of the double glazing solar module of present embodiment promotes 2 ~ 3%.
Execution mode three:
As shown in Figure 2, glass 5 is common float glass, and the metallic matrix reflectance coating is example with the aluminium foil, and aluminium foil directly is fitted in the outer surface at the float glass back side with film coating process, and its reflectivity can be up to 96%.Because the high relatively reflection polymeric matrix of aluminium foil reflectance coating reflectance coating has superiority aspect heat radiation, even so under the situation of rete reflectivity unanimity, long-term work temperature with double glazing solar module of aluminium foil reflectance coating can be lower, and lower working temperature helps the double glazing solar module to produce higher electric energy.The aluminium foil reflectance coating more has superiority in the applications that does not require the direct visible light transmissivity of construction material.
Though described execution mode of the present utility model in conjunction with the accompanying drawings, those of ordinary skills can make various distortion or modification within the scope of the appended claims.
