Description

Novel solar battery backboard
Technical field
The present invention relates to technical field of solar batteries, particularly the solar cell backboard technical field specifically is meant a kind of novel solar battery backboard.
Background technology
Because a large amount of uses of solar cell, each country, company have proposed many structures and have applied for many patents accordingly the backboard of solar cell.Structure relatively more commonly used at present is the TPT structure, wherein T refers to the Tedlar film of E.I.Du Pont Company, and composition is polyvinyl fluoride (PVF), and P refers to PETG (PET) film, therefore TPT refers to the PVF/PET/PVF structure, and is bonding with suitable bonding agent between three-layer thin-film.The typical production merchant of the backboard of TPT structure is the Isovolta company in Europe.The main effect of PVF film is weather-proof, and the whole world has only du pont company production, price height, supply monopolization.For saving cost, can substitute by the weaker plastic film of weatherability towards the PVF of solar battery sheet layer.So reason, the backboard (seeing patent application WO2004/091901A2) of TPE structure has been invented by the Madico company of the U.S..Wherein E refers to ethylene-vinyl acetate resin, is called for short EVA.The structure of TPE backboard is PVF/PET/EVA.The backboard that 3M company produces also is similar structure, uses THV (hexafluoropropylene (HFP)/tetrafluoroethylene (TFE)-vinylidene) film to be weathering layer, and structure is THV/PET/EVA, has also applied for patent (seeing patent application US2006/0280922A1).The patent of 3M attempts to cover fluoroplastics all except that PVF and all polyolefin.Polyolefinic definition has covered the plastics of all carbon-to-carbon structures, and kind is very many, and each plastics performance differs greatly.The fluoroplastics surface energy is low, except that PVF and THV are that other fluoroplastics are very difficult to bonding the easiest comparatively speaking bonding kind.So only can't realize structure except that THV/PET/EVA by its statement of applying for a patent.Other u s company is just attempting adopting ECTFE (ethene chlorotrifluoroethylene), ETFE (ethylene tetrafluoroethylene copolymer) as back veneer material, but does not also have commercial product.
PVDF formal name used at school in the fluoroplastics is a Kynoar, and molecular structure is-(CF 2-CH 2) n-(CH 2-CF 2) n-.Its supplier is many, likes companies such as richnesses, Eastern Mountain chemical industry, hugeization such as three of the Da Jin of Japan, Asahi Glass, French Acker agate, Italian Su Wei, China.PVDF can use the processing technology of thermoplastics to produce film, such as curtain coating or blown film, also can make coating, coating film forming.The PVDF film has high automatically cleaning ability, and extraordinary water, oxygen barrier performance are arranged.With the performance of PVDF, it should be fit to do the weathering protective layer of solar cell backboard very much.But the PVDF surface energy is low, can't directly use.
Polyethylene (PE) is the polymer of ethene, and molecular structure is-(CH 2-CH 2) n-.Contain a large amount of ethene segments in the commonly used glued membrane EVA molecular structure in the solar module, the compatibility of itself and PE is very good.Both can be bonded together under molten condition fully.
