Description
Technical field
The present invention relates to technical field of solar batteries, more particularly to solar cell backboard technical field.
Background technology
Solar power generation is a kind of green regenerative energy sources of cleaning, is more come in traditional energy exhausted, environmental pollution increasingly
Under stronger background, solar power generation is increasingly favored by people.With the development of society, market is to solar power generation skill
The increasingly diversification of the demand of art.
The backboard major part of the solar cell of current commercialization uses fluoroplastics as outermost weathering layer, gathers to benzene two
Formic acid glycol ester (PET) is used as middle structure enhancement layer, polyethylene (PE) or ethylene-vinyl acetate copolymer (EVA)
As the internal layer fitted with EVA adhesive film.Also needed between outside weathering layer and intermediate layer, intermediate layer and internal layer viscous with adhesive
Connect.This class formation is five-layer structure, such as the backboard (see patent application WO2004/091901A2) of U.S. Madico companies application.
The subject matter brought using this structure has：(1) PET facile hydrolysis, the danger for having aging crushing during long-term use.PET is two-way
The production equipment of oriented film is very expensive, causes that such PET's is expensive, improves the production cost of whole backboard.(2)
Binding agent price, requirement of the backboard to ageing resistace is very high, you must use extraordinary binding agent, and common is compound
Type backboard needs two layer binders, and its cost is one of the reason for backboard cost cannot be reduced.(3) answering for compound backboard is produced
Closing operation can produce percent defective higher.Conventional backboard needs to be combined twice, and what is thus brought is low yield rate.
As described above, use PET as structure enhancement layer in existing backboard, pasted or coating fluorine modeling in its both sides
Material, polyolefin.PET is generally using the BOPET of biaxial tension.But PET is very easy to hydrolysis as polyester material.In the market is
The resistant to hydrolysis PET of meaning, its hydrolysis rate for slowing down PET by adding the hydrolysis-resisting agent neutralizing hydrolysis acid for producing of alkalescence.But
Itself it is the material of consumption-type, it is impossible to be truly realized resistant to hydrolysis, can only to a certain extent slows down the hydrolysis of PET.
Polyethylene (PE) is the most commonly used polyolefine material, is also the maximum plastics of current worldwide production amount, great Liang Yu
Packaging for foodstuff, medical packaging, agricultural film, cable jacket, stationery Hardware fitting etc..Its price is low, supplier is more, such as sinopec,
Dow Chemical, South Korea's lake petrochemical industry etc..In solar energy industry, it is used as being close to EVA adhesive film (the dilute vinegar of second in backboard
Sour ethylene copolymer) one layer, generally from low density polyethylene (LDPE) (LDPE).Reason be its segment with EVA in E (ethene) phase
Together, and fusion range is low, between 90-120 degrees Celsius, in up to 150 degree or so of solar components process because
Heating is melted and the EVA (60-80 degree Celsius) lower with melt temperature is blended completely.But because its melt temperature is low, adding
Basic fusing during work and cannot be separately as the structure enhancement layer of backboard.And some other dystectic olefin material such as height
Density polyethylene (HDPE), polypropylene (PP) completely cannot be with EVA bond vitrifieds, and melt temperature scope and solar components
Processing temperature all closely.And other olefin materials such as POE, EVA melt temperature is also lower than LDPE.In polyolefin
In, there is no melt temperature to exceed the material of more than 20 degrees Celsius of solar components processing temperature.Polyolefine material water-fast in itself
Solution property is better than PET, so some patents substitute the structure enhancement layer that PET makees solar energy backboard, but polyene using polyolefine material
Hydrocarbon melt temperature scope in itself is simultaneously improper.It is that polyolefine material completely cannot and the melting temperature of PET is more than 180 degrees Celsius
Substitute.It is to use using the backboard of entirely olefin material if not changing existing solar components processing conditions
's.
Hydrogenated styrene-butadiene resin (SEBS) is substantially a kind of special rubber, its be styrene-butadiene-
The polymer of styryl structures, can be that block polymer can also be atactic polymer.Its production is made will by using hydrogen
A kind of special plastics elastic body of the butadiene double bond saturation in SBR styrene butadiene rubberses.It is characterized in tool simultaneously
The characteristics of for rubber and plastics, there are elasticity very high, toughness and weatherability, but can add by the method for plastic processing
Work.During its individualism, different from the particle profile of polyolefin plastics, but exist with fluffy flocculence.While SEBS
Melt temperature scope is high, and more than 170-180 degrees Celsius, indivedual ranks are even more than 200 degrees Celsius.And polyolefin elastomer,
I.e. the copolymer of ethene and octene or ethene and butylene, has elasticity higher but without toughness, and melt temperature is very low, leads to
Often between 50-70 degrees Celsius.Additionally, due to the benzene ring structure in SEBS, it can be with other plastics phases containing benzene ring structure
Hold, such as polystyrene, polyphenylene oxide etc..The usual melt temperature of plastics containing benzene ring structure is much higher compared with the plastics of olefines.
SEBS is used as a kind of more special material, and supplier is few, and the main supplier in the whole world rises and Taiwan rubber company for section of the U.S..
It is very big to the cost pressure of solar photovoltaic assembly at present, its energy is wished in the case where existing processing conditions is not changed
Not only low cost but also ageing-resistant performance is good.Therefore, in the urgent need to finding hydrolytic Resistance better than PET, while the lower replacement of cost
Product.
