Abstract
A back membrane of a solar energy battery pack relates to an assembly used in a solar energy battery and adopts a three-layer structure, wherein the middle layer is a PET polyester film layer (2), and fluororesin film layers (1 and 1a) are arranged on the upper and the lower surfaces of the PET polyester film layer (2) in a composite manner; the thickness of the fluororesin film layer arranged on the upper surface of the PET polyester film layer (2) in a composite manner is 0.15-0.25mm; the thickness of the PET polyester film layer (2) is 0.25mm-0.35mm; and the fluororesin film layer (1a) arranged on the lower surface of the PET polyester film layer (2) in a composite manner is 0.3mm-0.4mm. The back membrane of the utility model adopts the fluororesin films on the upper and the lower layers, thereby having the excellent fluoroplastic properties of aging resistance, corrosion prevention, stain resistance and water repellent; and meanwhile, due to the adoption of the PET polyester film on the middle layer, the back membrane has perfect mechanical strength, effectively prevents other media like water, oxygen gas, corrosive gases and liquids from corroding a solar energy battery silicon wafer, has high gloss retention and maintains color and luster all the year round.
Description
Technical field
The utility model relates to a kind of assembly that is used for solar cell, is specifically related to a kind of solar module notacoria.
Background technology
Solar energy is human inexhaustible regenerative resource, has sufficient spatter property, absolute fail safe, relative popularity, certain longevity and non-maintaining property, the abundance of resource and potential advantages such as economy.Along with the aggravation and the environmental protection needs of energy crisis, the development and use of solar energy come into one's own day by day.In the middle of effective utilization of solar energy, when solar photoelectric utilizes this year with fastest developing speed, have the research field of vigor most.
Topmost solar module as the solar photoelectric utilization is to be formed by the vacuum heat seal by energy ultrawhite figured glass, ethylene-vinyl acetate copolymer EVA glued membrane, crystalline silicon, EVA glued membrane, notacoria.Notacoria plays skeleton and to the protective effect of crystalline silicon.
At present, the substrate notacoria of solar cell mainly adopts a kind of TPT notacoria, the two-layer up and down polyvinyl fluoride material that all adopts, because polyvinyl fluoride thin film adhesive production technology in short supply, anti-aging and accurate complex technique can not get solving, make only account for battery component cost 1% less than notacoria production cost, processing technology require high, being not easy to promote, is the great bottleneck of restriction solar cell industry development.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of solar module notacoria, and the levels of notacoria adopts fluorine resin film, effectively improves the notacoria various aspects of performance.
Described solar module notacoria is characterized in that being three-decker, and the intermediate layer is a PET polyester rete 2, compound respectively fluorine resin film layer 1, the 1a of being provided with in the upper and lower surface of PET polyester rete 2.
Described solar module notacoria is characterized in that fluorine resin film layer 1 thickness of the compound setting of described PET polyester rete 2 upper surfaces is the 0.15-0.25 millimeter.
Described solar module notacoria is characterized in that described PET polyester rete 2 thickness are the 0.25-0.35 millimeter.
Described solar module notacoria is characterized in that the fluorine resin film layer 1a thickness of the compound setting of described PET polyester rete 2 lower surfaces is the 0.3-0.4 millimeter.
The utility model is simple in structure, reasonable in design, the levels of notacoria adopts fluorine resin film, have the fluoroplastics high-quality ageing-resistant, corrosion-resistant, resistant is hydrophobic, the PET polyester film is adopted in the intermediate layer, have excellent mechanical strength, can prevent the erosion to silicon chip of solar cell such as other medium such as water, oxygen, corrosive gas, liquid (as acid rain) effectively.And the gloss retention height can keep the color and luster of himself all the year round.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1,1a-fluorine resin film layer, 2-PET polyester rete.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The solar module notacoria comprises three-decker, and the intermediate layer is a PET polyester rete 2, compound respectively fluorine resin film layer 1, the 1a of being provided with in the upper and lower surface of PET polyester rete 2.Fluorine resin film layer 1 thickness of the compound setting of PET polyester rete 2 upper surfaces is the 0.15-0.25 millimeter.PET polyester rete 2 thickness are the 0.25-0.35 millimeter.The fluorine resin film layer 1a thickness of the compound setting of PET polyester rete 2 lower surfaces is the 0.3-0.4 millimeter.
