The utility model discloses light loss when not only having reduced the light incidence to through the secondary reflection of light, increased the incident volume that gets into the light of battery, improved 5.66% with the generating efficiency.
Description
Technical field
This utility model relates to photoelectricity and building materials field, is specifically related to a kind of double matte the most double glass photovoltaic module.
Background technology
Double glass photovoltaic modulies, refer to the solar photovoltaic assembly utilizing layer glass doubling to encapsulate.Along with the technology of photovoltaic industry develops, raising photovoltaic module efficiency, reduction cost are to adapt to the marketing policy and the inexorable trend of consumption market development.Photovoltaic module industry development production capacity surplus at present, technology, efficiency are uneven, serious waste energy resources, in order to ensure the healthy and sustainable development of China's photovoltaic industry, National Energy Board, Ministry of Industry and Information have put into effect a series of photovoltaic policy, more and more higher to photovoltaic module efficiency requirements, and the lifting of component efficiency is directly affected by upstream supply chain polycrystalline silicon battery plate efficiency.Present stage, it is only the research and development in photovoltaic cell efficiency mostly that efficiency is improved in photovoltaic module field, is mostly in high expensive cost, or simply in laboratory gross data, also has a certain distance away from mass volume production.The double matte the most double glass photovoltaic module of my company is to utilize encapsulation technology that sunlight achieves two secondary reflections and twice antireflective technology, it is ensured that the highest electricity conversion of photovoltaic cell, is that the science and technology of the up-to-date leading technology of photovoltaic module converts achievement.The solar double-glass assemblies of this kind of structure not only increases assembly anti-PID ability, service life, fire safety, anti-hidden problem of splitting, and is substantially reduced production and installation cost, can create economical value, meet photovoltaic industry policy, market development rule.
At present, domestic solar components improves inefficient by packaging technology, the header board common ultra-clear glasses of many employings of present stage assembly, the direct reflection of this glass is the most serious, light transmission efficiency is the lowest, and the amount of incident of light is not enough, leverages the utilization rate of solar energy, there is technique improvement in photovoltaic module internal structure secondary reflection technology, reduces generating efficiency.
Summary of the invention
The purpose of this utility model is the shortcoming and defect overcoming prior art, it is provided that a kind of double mattes the most double glass photovoltaic module that can be effectively improved generating efficiency, reliable in quality.
For realizing object above, technical solution of the present utility model is: a kind of double matte the most double glass photovoltaic modulies, including glass front plate and glass back plate, some cell pieces connected by reflective interconnector it are provided with between described glass front plate and glass back plate, it is characterized in that: described front glass sheet is double matte coated glasses, seal bonding by transparent adhesive film and increasing reflecting film between described back-panel glass and front glass sheet, told cell piece is fixed on the separating surface of transparent adhesive film and increasing reflecting film, and described glass back plate is fixed with 3 Split type connecting boxes.
Described transparent adhesive film and increasing reflecting film are the copolymer adhesive film of ethene-vinyl acetate.
Described rosette uses split-type design, and is fixedly bonded in glass back plate by silicone adhesive.
Described interconnector is reflection-type SAC band.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model uses double matte coated glass as the front glass sheet of assembly, the special antireflective know-why utilizing glass not only reduces the light loss that incident ray causes because of direct reflection, also add the amount of incident of incident ray simultaneously, utilize simultaneously and increase reflection interconnecting strip, glued membrane and the cooperation of film plating layer technology, cell piece generating district is added with twice reflective surface area of UV light closer to a floor, add the amount of incident of the light entering photovoltaic cell, generating efficiency is improve 5.66%.
2, the rosette in this utility model uses split design, decreases the usage amount of busbar, cable, thus reduces line loss, reduces solar double-glass assemblies production cost.
3, the assembly in this utility model uses Rimless design, compared with general components, has effectively evaded frame dust accretions and has hidden cell piece phenomenon, is very easy to, by rain drop erosion, improve the generating efficiency in assembly actual motion in power station.

In figure: glass back plate 1, front glass sheet 2, interconnector 3, cell piece 4, transparent adhesive film 5, increase reflecting film 6, rosette 7.
Detailed description of the invention
Illustrate with detailed description of the invention, this utility model to be described in further detail below in conjunction with accompanying drawing.
nullSee Fig. 1-Fig. 3，A kind of double matte the most double glass photovoltaic module，Including glass back plate 1 and front glass sheet 2，Some cell pieces 4 it are provided with between described glass back plate 1 and front glass sheet 2，Cell piece 4 uses 156*156 monocrystalline high efficiency anti-PID cell piece，3 1.5*0.23 alloy strip flush welds are used to connect between every cell piece 4，Described front glass sheet 2 is double matte coated glasses，Because its upper and lower surface has certain roughness，Sunlight all can produce the effect of antireflective increasing light transmittance through its upper and lower surface，It is tightly connected by copolymer adhesive film transparent adhesive film 5 and increasing reflecting film 6 that material is ethene-vinyl acetate between described glass back plate 1 and front glass sheet 2，But compare in its composition of transparent adhesive film 5 due to increasing reflecting film 6 and add titanium dioxide，Therefore the relatively transparent glued membrane of color 5 increasing reflecting film 6 wants deep，When producing，Transparent adhesive film 5 to be positioned at the top (cell piece front) increasing reflecting film 6，Told cell piece 4 is fixed on the separating surface of transparent adhesive film 5 and increasing reflecting film 6，The rosette of split type distribution it is fixed with in described glass back plate 1，And be fixedly connected in glass back plate 1 by silicone aging resistance glue.
Operation principle of the present utility model is: sunlight is injected from glass outer 2 surface, owing to double mattes of front glass sheet 2 are arranged, decrease the light loss that incident ray causes because of direct reflection, roughness also add the amount of incident of incident ray simultaneously, now light enters component internal, after light passes transparent adhesive film 5, increasing reflecting film 6 can be encountered, deeper owing to increasing the color of reflecting film 6, light can carry out primary event on transparent adhesive film 5 and the separating surface increasing reflecting film 6, light can reflex on the film plating layer of front glass sheet 2, film plating layer reflection technology makes light carry out second time reflection, and reflection light is mapped on cell piece 4, now cell piece 4 absorbs all of light, the superposition of incident illumination and reflection light will be greatly improved discovery efficiency.
