Description
Background of invention
Description of Related Art
The solar energy that photovoltaic module uses is one of most promising alternative energy source of oil, and in this century, oil is just depleted.But, to produce and the process of installation photovoltaic component remains costliness.Typical photovoltaic module is made up of the protective seal at the transparent front sheet of glass or flexibility, solar cell, sealant, protectiveness backboard, covering assemblies edge and the aluminum frame that covers sealing.As shown in Figure 1, front panel 10, backboard 20 and sealant 30 and 30 ' are designed to protect the impact of array 40 not climate factor, humidity, mechanical load and impact.And these parts provide the electrical isolation for personal security and electric leakage.Protectiveness backboard 20 is intended to the service life and the efficiency that improve photovoltaic module, thus reduces the unit power cost of photovoltaic electric current.In order to realize the Transmission light of height, front panel 10 and sealant 30 and 30 ' must be transparent, but must be highly opaque to obtain backboard attractive in appearance, and must have highly reflective for functional object backboard.For a lot of reasons, expect that solar module is frivolous, these reasons comprise and are particularly useful for building (with the photovoltaic (PV) of building one) and the weight applied of space reduces, and Military Application (be combined in soldier's equipment etc. in).In addition, frivolous element assists is in reducing costs.The reduction of the quantity of material used also makes this technology " green " more, thus has saved more natural resources.
The present arrangements manufacturing frivolous solar cell is in conjunction with frivolous backboard.But back cladding material also must have certain moisture resistance and infiltrate to prevent moisture and water, and the capped parts of such as photovoltaic element, wire and electrode may be caused to get rusty for the infiltration of moisture and water and solar cell damages.In addition, backboard should provide electrical isolation, mechanical protection, certain ultraviolet (UV) stability, to the tack of sealant and the ability connecting output line.
The protectiveness backboard normally laminated product of current use.Fig. 2 provides the diagram of typical laminate backing sheet 20.Lamination by as the most common of critical component is
polyvinyl fluoride rete 22, polyester (PET) rete 24 and ethene-vinyl acetate (EVA) copolymer rete 26 form.EVA layer 26 bonds with the sealant layer 30 in assembly and is used as dielectric layer, and EVA layer 26 has good moisture barrier characteristics.The size of this EVA is stable.White EVA makes power significantly improve.Polyester layer 24 is very firm, has excellent dielectricity, dimensionally stable, and also has good moisture barrier characteristics.Polyvinyl fluoride layer 22 is used as very weather-proof layer.
Even if these retes have met the performance standard in the actual use procedure of required test neutralization, but still there is some limitation, as high in cost and acquisition
rete is restricted.Such as PVF
eCTFE
at the temperature that cannot raise in environment temperature or appropriateness, such material is processed with another shortcoming of the material of the prior art of other fluoropolymer.Such as, use high boiler (usually, to orientation
use dimethyl acetamide, right
sP uses propene carbonate) make PVF rete by casting technique by diffusion.The boiling point of dimethyl acetamide is 164-166 DEG C, and the boiling point of propene carbonate is 200 DEG C.Must 160 DEG C and 90% or higher solvent under spread.Due to the thermal instability of PVF resin, higher temperature can not be accepted: the melting Sum decomposition temperature of PVF resin too close to such an extent as to PVF can decompose in the process of curing.Therefore, exist
there is residual solvent in rete always.DuPont is reported in all orientations
dimethylacetylamide (DMAC) residual quantity of 0.05wt% to 1.0wt% is there is in PVF rete.
Or, ECTFE
rete is made by melt extruding technique at 350 DEG C-375 DEG C.Therefore, ECTFE
rete can not easily mix with pigment, clay etc., and this rete is also expensive.
5th, 741, No. 370 United States Patent (USP)s propose, manufacture and assembly installation cost can be reduced by thermoplastic olefin is used as backsheet material, described thermoplastic olefin comprises two kinds of different ionomeric combinations, the such as combination of sodium ionomer and zinc ionomer, and this combination is described to produce synergy, and the water vapor barrier property of back veneer material is increased on the barrier properties of any single ionomer component by described synergy.This patent also discloses the use of the ionomer encapsulant with two ionomer tergite.
But National Renewable Energy laboratory (NREL) report, ionomer resin comprises methacrylic acid that is free and that combine, and its needs use stainless steel instrument in melt-processed process, thus add manufacturing cost.PVMaT in the subcontract report of Solarex photovoltaic module manufacturing technology year improves (PVMaT Improvements in the Solarex PhotovoltaicModule Manufacturing Technology Annual Subcontract Report), on April 30 ,-1999 years on the 5th May in 1998, National Renewable Energy Laboratory, in January, 2000 NREL/SR-520-27643.
