Description
Technical field
The present invention relates to a kind of extra-weather-proof protecting solar cell films and preparation method thereof.
Background technique
Solar power generation is pollution-free with its, sustainable, total amount is big, distribution is wide, using it is various informative the advantages that constitute too
Important component in positive energy energy strategy.The encouragement energetically of national governments was worldwide obtained in recent years, was won
It obtained considerable and developed by leaps and bounds.A kind of the solar battery as new energy, with conventional thermal power generation or other new
Energy such as wind-powered electricity generation, water power, nuclear power etc. is compared, and to keep its competitive advantage, then must embody its distinguished cost performance
Duration benign development can be obtained.For this purpose, the manufacturer and operator of each component part of solar battery do one's utmost
Carry out innovation research so that the cost performance of solar battery operation is continuously improved in ground.
Semiconductor solar cell --- crystal silicon solar batteries one in solar battery kind, based on element silicon
Directly in occupation of leading position.Crystal silicon solar batteries are primarily configured as being led by high transparency foreboard, encapsulating film, silver paste or aluminium paste
These materials are passed through heating by the laminated construction that the multilayered structures such as line, polycrystalline or monocrystalline silicon piece, encapsulating film and battery back-sheet are formed
The mode of lamination forms, and after sealing joint strip and frame assembling, mixing terminal box can be obtained crystal silicon solar batteries component.
Wherein, it is the key point for determining battery cost performance, and steam and oxygen that can the crystal silicon chip as " heart " efficiently run for a long time
Gas is then crystal silicon chip " fatal killer ".The main function of the backboard of one of important component as crystal silicon battery is to use
In protecting and supporting cell piece under the diversified open-air conditions such as ultraviolet light, dust storm, sleet, high/low temperature, still it is able to maintain good
Good luck row, it is necessary to have outstanding resistance ultraviolet irradiation, dust storm erosion, moisture attacks, aggressive oxygen energy.Moreover, big compression ring
Ultraviolet light irradiation, dust storm, sleet, high/low temperature in border etc. are not self-existent, therefore in common product development process
In cannot illustrate the quality of properties of product using simple independent test.It needs in a variety of conditions and deposit in the case where can expire
Sufficient requirement can more steadily guarantee properties of product.
Traditional solar energy backboard membrane is the composite membrane of " TPT ", " KPK " or " TPE " sandwich structure currently on the market,
Middle T layers be Du Pont Tedlar film, P layers be PET modifier film, K layers be Acker Ma Kynar film, E layers are that polyolefin is thin
Film.The major function of the fluorine material of outer layer is to prevent the effect of ultraviolet light, and P layers with excellent mechanical stability and good
Barrier property, T or K layers with the powerful guarantee that P layers of synergistic effect is that solar energy backboard can be used for a long time outdoors, but by
It has passed through modification in T layers or K layers, the oxygen ability that actually blocks water is well below its theoretical duty, and P layers of hydrolytic resistance ratio
It is poor, eventually lead to the service life requirement that backboard is relatively inaccessible to 25 years.
On the other hand, global climate has diversity, if one kind area in China is such as Tibet, Hainan etc., as height
Its aging speed of the conventional backing plate of molecular material composition is significantly larger than two classes, three classes area.This is because, polymer material is in purple
Outside line, high temperature wet heat condition coexist down, can rapidly occur chemical structure change, so as to cause its physical property it is quick under
Drop, the speed that structure changes are far longer than single condition.Therefore, as protective film vital in solar battery, back
Can the correctness of plate cladding material selection be the key that guarantee battery life.And judge the important technology of the Protective coatings
Index includes mainly uvioresistant ability, moisture-resistant thermal energy power, water vapor rejection ability and oxygen obstruction ability, especially at a variety of
Part coexist under integration capability.The selection of protecting solar cell film should select suitable material according to the amblent air temperature of each department
Material is only the reliability solution of high performance-price ratio.
Patent CN101932443B discloses a kind of three layers of PVDF thin film for photovoltaic cell, has A/B/C structure,
Outermost layer and innermost layer use pure PVDF or its copolymer as cortex, and middle layer uses PVDF modifier.It is using the structure
Since PVDF itself has excellent uvioresistant performance and water vapor rejection performance, it is thus possible to play one to backboard middle layer of PET
Fixed protective effect.But the transmission of ultraviolet light can not be prevented as the PVDF of cortex or its copolymer itself, with the time
Extension ultraviolet light inevitably still can damage effect to the modifier component in middle layer, cause boundary layer point
From, and ultimately cause hidden danger.
Patent CN106585010A discloses a kind of photovoltaic back PVDF thin film of double-layer coextrusion, and cortex uses PVDF
+ PMMA+TiO2+ antioxidant system+ultraviolet absorber composed structure, using the photovoltaic back PVDF of the structure and conventional monolayers
Film is not significantly improved, and since the variation of chemical structure can occur under ultraviolet irradiation for PMMA ingredient itself therein,
Further across the damp and hot experience of high temperature, it will further speed up material degradation, finally cause failure risk.

It is an object of the invention to overcome the above deficiencies in the existing technologies, and it is reasonable super resistance to provide a kind of design
Protecting solar cell film and preparation method thereof is waited, there is obvious excellent uvioresistant, hydrothermal aging ability, while being had significant
Water vapor rejection ability and oxygen obstruction ability can more efficiently extend the service life of solar battery.
