Abstract
The invention relates to the field of solar cell module, and in particular relates to a solar cell module without a backboard. The solar cell module is provided with a glass front board and a photoelectric part, wherein a light receiving surface of the photoelectric part between the glass front board and the photoelectric part is provided with transparent resins with the average light transmittance of more than 90%; and the backlight surface of the glass front board opposite to the photoelectric part is provided with high-reflection resins with the average reflectivity of 70-90%. Through the invention, high output power of the solar cell mould is ensured, the backboard material is saved, the separation risk of the backboard is avoided, and the cost of the solar cell module is lowered.
Description
Technical field
The present invention relates to the solar module field, especially a kind of backboard solar module of exempting from makes assembly have high real output when can guarantee to save the assembly cost.
Background technology
At present, Chang Gui solar module is made of glass front plate, resin clip glued membrane, photoelectricity part, resin clip glued membrane, the stack of polymer backboard usually successively.In this traditional product structure, backboard mainly plays insulation, ageing-resistant effect.If use the highly reflective backboard, according to depth zero optically focused effect: 1) shine sunlight between the component internal battery by the backboard scattering and by the working region photoelectricity part of sensitive surface glass-reflected to assembly; 2) after the electromagnetic wave of part near infrared band sees through the photoelectricity part, still can reflex to the photoelectricity part of assembly; 3) shine battery sheet surface matte sunlight partly, in doubling film, the surface reflection of battery face, through glass, air interface secondary reflection, arrive the position, gap of photoelectricity part, through the reflection at the backboard/potting resin interface at position, gap, get back to other light accepting part positions of photoelectricity part once more via glass/air interface.Comprehensive above effect, the application of high reflective back plane has improved the utilance of spectrum, the output that has improved assembly, however the cost of manufacture of high reflective back plane is higher and the easy delamination of backboard.Particularly: high reflective backboard usually by outer fluoropolymer weathering layer, middle level be the insulating barrier polymer, with the composite bed of potting resin also be the weathering layer polymer usually.This compound structure is in long-term use, because the different thermal fatigues of every layer thermal coefficient of expansion cause delamination, or because of the bonding failure of interlayer sticky object causes delamination, in use there is very big delamination risk in backboard.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of backboard solar module of exempting from is provided, save the assembly cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of backboard solar module of exempting from, have glass front plate and photoelectricity part, photoelectricity part sensitive surface between glass front plate and the photoelectricity part is packaged with average transmittance greater than 90% transparent resin, and the shady face that photoelectricity partly deviates from glass front plate is packaged with the height reflection resin good with the transparent resin compatibility.Transparent resin has high light transmission, and the back spectrum to 300nm～380nm of curing reaches the average transmittance more than 90%, and refractive index and glass are close.High reflection resin requires to have ageing-resistant performance, certain mechanical strength, high insulation property, high flame resistance, high water resistant performance are arranged after the curing, spectrum to 300nm～1200nm has the highly reflective energy, high refractive index, ultraviolet is had high reflection or through performance, and its reflectivity is that reflectivity range is 70%～90%.
Further, described transparent resin is silicone rubber resina or epoxy resin, and silicone rubber resina has the highest light transmission, and epoxy resin is applicable to produces the less assembly of area.
Described high reflection resin is to add talcum powder, titanium dioxide, hollow glass microballoon filler in the silicone rubber resina or is to add talcum powder, titanium dioxide, hollow glass microballoon filler in the epoxy resin, by the interpolation of filler, can reach better high reflectance effect.
The invention has the beneficial effects as follows: a kind of backboard solar module of exempting from of the present invention, guaranteed that assembly has high power output, save back veneer material simultaneously, avoid the risk of backboard delamination, thereby reduced the assembly cost.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is an original structural representation of the present invention;
Fig. 2 is a structural representation of the present invention.
Among the figure 1, glass front plate, 2, the resin clip glued membrane, 3, the photoelectricity part, 4, the polymer backboard, 5, transparent resin, 6, high reflection resin.
Embodiment
The present invention is further illustrated with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1 be the original structural representation of solar module, solar module is made of 4 stacks of glass front plate 1, resin clip glued membrane 2, photoelectricity part 3, resin clip glued membrane 2, polymer backboard successively.
A kind of backboard solar module of exempting from as shown in Figure 2, have glass front plate 1 and photoelectricity part 3, photoelectricity part 3 sensitive surfaces between glass front plate 1 and the photoelectricity part 3 are provided with average transmittance greater than 90% transparent resin 5, and it is 70%～90% height reflection resin 6 that the shady face that photoelectricity part 3 deviates from glass front plate 1 is provided with average reflectance scope at 300nm～1200nm.
Embodiment one:
The transparent resin 5 of sensitive surface is selected silicone rubber resina for use, silicone rubber resina has very high light transmission in all resins, 280nm～1300nm solar spectrum mean transmissivity reaches more than 96%, traditional EVA, PVB doubling film light transmittance are about 90%, and silicon rubber can guarantee high weather resistance simultaneously.The height of shady face reflection resin 6 is for adding the filler of good insulation preformance such as talcum powder, titanium dioxide, hollow glass microballoon and good barrier property in the silicone rubber resina, to strengthen the albedo to sunlight.Assembly preparation technology is: glass front plate 1 lay, the transparent silicon rubber resin applies on the surface thereon then, then with the transparent silicon rubber resin top of photoelectricity part 3 laies in coating, transparent silicon rubber resin to sensitive surface carries out precuring then, shady face above photoelectricity part 3 applies high reflection resin 6 again, at last integral body is cured.
