Description
Technical field
The invention belongs to photovoltaic and manufacture field, be specifically related to a kind of solar energy backboard and solar module of solar module.
Background technology
Along with the development of modern industry, global energy crisis and atmosphere polluting problem become increasingly conspicuous, and therefore people replace traditional energy gradually in the urgent need to finding regenerative resource.And solar energy is as the regenerative resource of core, therefore in recent years, photovoltaic field more and more comes into one's own, and achieves and develop rapidly.Wherein, solar module is as the core texture energy of sunlight directly being changed into electric energy; its process structure mainly comprises: first multiple solar battery sheet is carried out series and parallel connection, then the solar battery sheet completing series and parallel connection is carried out packaging protection.Encapsulating structure mainly comprises: transparency carrier; general employing glass is made; for covering the sensitive surface of solar battery sheet; adopt that backboard is protected, the back side of support solar cell piece, adopt potting resin (being generally EVA plastics) to be filled in transparency carrier, gap between backboard and solar battery sheet simultaneously.Because solar energy backboard need be chronically exposed in outdoor environment, (instructions for use of current business solar module is 25 years), therefore it should possess high mechanical properties, good dimensional stability, anti-flammability, high-insulation and with outside the basic function of the high tack of potting resin, also should have very excellent, the permanent weather resistance comprised as heat-resisting, hydrolysis and resistance to ultraviolet etc., the test in useful life that solar module reaches 25 years could be met.
Solar energy backboard conventional in prior art mainly comprises three kinds: TPT type solar energy backboard, TPE type solar energy backboard and PPP type solar energy backboard.Wherein, TPT type solar energy backboard is after the biaxial tension PET film double spread adhesive for polyurethane by one deck 250 μm; at the PVF film of the two sides of PET film difference compound 30 μm; PVF film has superior outdoor environment weatherability (can reach more than 40 years); available protecting is as the PET of backboard main material, but the material cost of PVF is high.Wherein, TPE type solar energy backboard is after the biaxial tension PET film double spread adhesive for polyurethane by one deck 250 μm, at the PVF film of the lower surface compound 30 μm of PET film, and the PE of surface recombination 50 μm or eva film thereon, TPE type solar energy backboard has good weatherability, and relative to TPT type solar energy backboard, its cost of manufacture is lower, is also to use more type in existing market; Wherein, PPP solar energy backboard is after the biaxial tension PET film double spread adhesive for polyurethane by one deck 250 μm, in the hydrolysis PET film of the lower surface compound 50 μm of PET film, and the PE film of surface recombination 50 μm thereon, PPP type solar energy backboard cost is minimum, but its weatherability, not as TPT type solar energy backboard and TPE type solar energy backboard, therefore makes land used less in existing market.
From finding out above, the material of main part that current solar energy backboard adopts is PET, in order to guarantee that solar energy backboard possesses high mechanical properties, good dimensional stability, anti-flammability and high-insulation, but owing to containing a large amount of ester groups in PET molecular backbone, good compatibility is had with glassware for drinking water, the plasticising of easy generation water, even if the moisture of trace also can cause the degraded of PET molecular backbone, thus cause the mechanical performance of PET to be damaged, temperature then can make above-mentioned degradation process obviously accelerate when raising, therefore water and heat are the main causes causing PET material mechanical strength sharply to decline.In addition, ultra-violet radiation also can make the molecular weight of PET, strength and elongation significantly declines, and degree of crystallinity increases, thus the mechanical performance of PET material is damaged.And generally only have 30 μm due to the protective layer thickness being positioned at pet layer lower surface in solar energy backboard; in long outdoor overall situation uses; aqueous vapor and oxygen still can be penetrated into by lower surface protective layer and be positioned at middle pet layer; cause pet layer degraded, deterioration; final and potting resin departs from; make it lose efficacy to the protection of solar battery sheet and support function, and then cause decrease of power generation and even the solar module global failure of solar module.
Therefore be necessary to propose to improve to existing solar energy backboard, guaranteeing that it possesses high mechanical properties, good dimensional stability, anti-flammability, high-insulation and with under the prerequisite of the high tack of potting resin, also possess excellence, permanent comprising as heat-resisting, hydrolysis and resistance to ultraviolet etc. weather resistance simultaneously.
The technical scheme the most close with technical solution of the present invention has, publication number is that the Chinese invention patent of CN102414838A discloses a kind of used for solar batteries, its individual layer specifically formed by polyphenylene ether group resin layer or sandwich construction used for solar batteries, described polyphenylene ether group resin layer is by with durability, anti-flammability and excellent in dimensional stability, and the high polyphenylene oxide of adaptation between potting resin layer etc. is that the resin combination of principal component is formed.Although PPE material is compared with PET material, except possessing high mechanical properties, good dimensional stability, anti-flammability and high-insulation, also possess excellent heat-resisting, anti-hydrolytic performance.But find in actual applications, the ultra-violet resistance of PPE material is poor, studies and finds that this ruptures because the phenyl ring on the high polymer main chain of PPE material is very easy to be attacked by ultraviolet, cause PPE material to turn to be yellow, degrade and deterioration occurs through the application.Although this full patent texts discloses the various performances that multiple interpolation auxiliary agent improves PPE material further, as its patent specification the 9th page of-10 pages, but still the strong material of effective ultra-violet resistance is not disclosed to improve the poor technical problem of ultra-violet resistance of PPE material itself, this makes PPE material be subject to larger restriction as the material of main part of solar energy backboard.
This patent also discloses lamination layer structure (referring to its specification the 11st page of-12 pages), main employing arranges intermediate layer, in the upper and lower surface in intermediate layer, PPE layer is set, intention increases the mechanical strength of solar energy backboard, insulating properties and thermal endurance, but ultraviolet irradiation comes from the layer of solar energy backboard mostly, this patent all adopts by polyphenylene oxide as material of main part, and do not add the layer of layer (I) as solar energy backboard of the additive composition with excellent ultra-violet resistance, therefore be not difficult to find, this composite bed does not have essence to solve the technical problem of PPE material ultra-violet resistance difference completely, and such composite construction also can cause the tack of PPE material and potting resin (being generally EVA resin) poor simultaneously, packaging effect cannot be guaranteed, need to add and be beneficial to adding material that layer (I) and potting resin adhere in a large number or arrange separately easy adhesive linkage, technique is comparatively loaded down with trivial details.
Although this patent also adopts a large amount of length (referring to specification the 25th page of-30 pages) to record employing have selection UV stable group, the acrylic copolymer of at least one group in ultraviolet-absorbing group and cycloalkyl is used as a kind of material in inorganic thin film layer (being a type of layer (II) structure of this patent), and in multiple lamination layer structure (referring to the 18th page, specification) disclosed in this patent, only using this layer (II) as intermediate layer or as the upper epidermis adhered to potting resin, and still adopt by polyphenylene oxide as material of main part, and do not add the layer of layer (I) as solar energy backboard of the additive composition with excellent ultra-violet resistance, therefore essence is not still had to solve the technical problem of PPE material ultra-violet resistance difference.In addition, do not considering under the prerequisite producing other counter productives, the applicant makes creative work hypothesis, using layer (I) as intermediate layer, and at least take more than 50% of solar energy backboard gross thickness disclosed in this patent due to the thickness of the layer (I) be made up of as material of main part polyphenylene oxide, even if UV stable group will be had, the inorganic thin film of the acrylic copolymer of at least one group in ultraviolet-absorbing group and cycloalkyl is as the protective layer of lower surface, with the TPT type solar energy backboard of existing routine, the technical problem that TPE type solar energy backboard and PPP type solar energy backboard exist is similar, because the thickness of upper layer is lower, in long-term outdoor environment uses, ultraviolet light still can be penetrated into by upper layer (mainly layer) and be positioned at middle pet layer, pet layer is caused to be degraded, deterioration, final and potting resin departs from, it is made to lose efficacy to the protection of solar battery sheet and support function, and then cause decrease of power generation and even the solar module global failure of solar module.
In addition, the technical scheme combination of this patent disclosure too much, and its additive types coverage rate disclosed is excessively wide, but in fact, these miscellaneous additives are not all have good effect for the various performances improving solar energy backboard, therefore, those skilled in the art are difficult to acquisition of technology solar energy backboard satisfactory for result on the basis of this patent at all.
Therefore comprehensive above content, still solves above technical problem in the urgent need to seeking optimisation technique scheme.
