Pond encapsulating material and Technology are to improve the key technology that photovoltaic module service life reduction use cost reaches higher economic benefit.
Important component part of the solar energy packaging adhesive film as solar photovoltaic assembly, it plays and seals and protect solar battery sheet,
Bonding upper and lower bottom plate, the effect for preventing steam from invading are required in performance with good light transmittance and anti-steam function, excellent
Ageing resistace and adhesive property.The solar photovoltaic assembly of countries in the world enterprise production at present is generally using EVA as envelope
Package material, EVA is ethylene-acetate ethylene copolymer, its objective reality some defects, such as anti-ultraviolet aging performance and moisture-resisting
Heat ageing ability and anti-steam poor-performing, easily degraded xanthochromia and fracture.These can all cause photovoltaic module service life to drop
Low and generating efficiency is greatly lowered.As EVA is ethylene-acetate ethylene copolymer, which is in light, heat, cold, oxygen and steam
In the presence of can produce unsaturated double-bond, acetic acid, a small amount of acetaldehyde, ketone group and lactone structure etc., cause photovoltaic module light transmittance
And photoelectric conversion rate declines, internal xanthochromia, season cracking, due also to EVA is in ageing process, the acidic materials of release can be in group
Electrode erosion is made to cause photovoltaic module generating efficiency step-down or even scrap, be cracked in part.In recent years, some photovoltaics
The enterprise of component and solar power station have been reported that the photovoltaic module of solaode under natural climate condition because of encapsulating material
Be heated wet etc. affect to turn yellow, cracking, degumming and cause the photoelectric transformation efficiency of solaode to substantially reduce and service life
Shorten and whole example extremely, these examples are related to ageing-resistant, the chronicity of encapsulating material, and photovoltaic module obtains the longer use longevity
Order and reach higher target economical efficiency, and both at home and abroad glued membrane used for packaging solar battery assembly is proposed up to 30
Service life target more than year.Therefore seek one kind and can substitute EVA, and there is high water vapor rejection, can take with any cell piece
It is better with PID is reached, there is good weatherability, reach the long-acting use of component and higher economic goal.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of inexpensive for above-mentioned prior art, high-performance,
