The invention further provides a method for preparing the solar cell frame; the method comprises the following steps of: infiltrating the preheated fiber in the fused thermoplastic resin, and shaping the fiber in a mold to obtain fiber reinforced thermoplastic resin profiles; and assembling the fiber reinforced thermoplastic resin profiles so as to obtain the solar cell frame. According to the invention, the fiber reinforced thermoplastic resin is used to replace aluminum profiles to produce the solar cell frame, so that the solar cell frame has excellent mechanical performance and aging performance, and excellent processing performance; and through a simple and feasible pulling and extruding shaping technology, the weight and cost of the solar cell frame can be reduced. The tests show that the tensile strength, aging performance, adhesive performance and tapping performance of the solar cell frame provided by the invention are better than the solar cell frame produced by the aluminum profiles.
Description
Technical field
The invention belongs to technical field of solar batteries, relate in particular to a kind of solar cell frame and preparation method thereof.
Background technology
Along with the exhaustion of fossil energy, various renewable new forms of energy industries are surging forward, according to (the JRC of Joint Research Centre of European Union; Joint Research Center European Commission) prediction; To the year two thousand fifty, the ratio of renewable energy source will account for 52% above traditional energy; Wherein sun power accounts for the last 1/2, and about 28%; To the end of this century, the ratio of renewable energy source will account for 86%, sun power will occupy wherein about 67%.
Solar electrical energy generation is the important component part in the solar energy strategy, and wherein, the photovoltaic industry especially obtains the attention of national governments, and industrialization speed is very fast.Prior art discloses multiple photovoltaic cell, claims solar cell again.It is the battery of main body and the battery that is the main body with the multielement semi-conductor that solar cell mainly is divided into the element silicon.With the elemental semiconductor is that main solar cell mainly comprises selenium photoelectric cell, cadmium sulphide cell, copper-indium-galliun-selenium battery, cadmium telluride battery, gallium arsenide battery, indium phosphide solar cell, dye-sensitized solar cells and organic film solar cell etc.; With the elemental semiconductor is that main solar cell has the little advantage of element usage quantity; Some can also make concentrating solar battery to increase electricity conversion; But the photovoltaic cell commercialization successful story that with the elemental semiconductor is the master at present is fewer, and the engineering that lacks on-site generated power is accumulated experience.In addition, some element content in the earth's crust is limited, and in refinement and the use environment is had pollution, like gallium, cadmium and arsenic etc.And the content of silicon in the earth's crust is 27.6%, is only second to oxygen; And; The technology of purification high purity silicon (>=99.9999%) mature and reliable comparatively in industry; Therefore, comprise that the element silicon batteries such as crystal silicon solar batteries of polysilicon and silicon single crystal have formed a flourish industry, will occupy dominant position in foreseeable future.
The rhythmo structure that mainly being configured to of crystal silicon solar batteries formed by high transparent front plate, encapsulating film, silver slurry or multilayered structures such as aluminium paste lead, polycrystalline or monocrystalline silicon piece, encapsulating film and battery back-sheet.With of the mode moulding of these materials through heated lamination, after use joint strip and the frame assembling, mix terminal box, can obtain crystal silicon solar batteries.Wherein, frame mainly is that core components such as battery sheet are carried out packaging protection, to the performance of crystal silicon solar batteries and have material impact work-ing life.
In the prior art, frame mainly adopts aluminium section bar to process through the cold extrusion processing mode, and not only energy consumption, cost are high, and are easy to generate leftover bits, cause waste.In addition, metallic aluminium is prone to oxidized, cause solar cell out of doors in the use life-span shorter.
Summary of the invention
In view of this, the technical problem that the present invention will solve is to provide a kind of solar cell frame and preparation method thereof, and solar cell frame provided by the invention has good mechanical performance and aging resistance, can prolong the outdoor work-ing life of solar cell.
The invention provides a kind of solar cell frame, its material is fibre-reinforced thermoplastic resin.
Preferably, said thermoplastic resin is one or more in polymeric amide, polyester, polycarbonate, polyolefine, vinyl cyanide and the Yodo Sol GH 28.
Preferably, said thermoplastic resin is one or more of polyamide 66, polyamide 6, polyethylene terephthalate, polybutylene terephthalate, PTT, Vestolen PP 7052, acrylonitrile-butadiene-styrene (ABS) and propenoate-perbutan.
Preferably, said fiber is a macrofiber.
Preferably, said macrofiber is one or more in spun glass, polymer fiber, thomel, flaxen fiber and the bamboo fibers.
Preferably, said quality of fiber mark is 30%～80%.
Preferably, also comprise in oxidation inhibitor, stablizer, toughner, lubricant and the anti-ultraviolet ageing agent one or more in the said thermoplastic resin.
The present invention also provides a kind of preparation method of solar cell frame, may further comprise the steps:
Fiber after the preheating is soaked in the fused thermoplastic resin, after die for molding, obtain fibre-reinforced thermoplastic resin profiled material;
With said fibre-reinforced thermoplastic resin profiled material assembling, obtain the solar cell frame.
Preferably, also comprise in oxidation inhibitor, stablizer, toughner, lubricant and the anti-ultraviolet ageing agent one or more in the said thermoplastic resin.
Preferably, said being assembled into through screw connects, is connected with draw-in groove, connects, welds or bond through sticker through groove through being threaded, passing through bayonet socket.
Compared with prior art, the material of solar cell frame provided by the invention is fibre-reinforced thermoplastic resin, can be in polymeric amide, polyester, polycarbonate, polyolefine, vinyl cyanide and the Yodo Sol GH 28 one or more.The present invention replaces made from aluminium profile solar cell frame with fibre-reinforced thermoplastic resin; It not only has good mechanical performance and aging resistance; And has a good processing properties; Can prepare through simple pultrusion molding process, thus the weight and the cost of reduction solar cell frame.Experiment shows; Compare with aluminium section bar solar cell frame; The weight of solar cell frame provided by the invention can alleviate 1/3～1/2; Cost can descend 30%～40%, but its tensile strength can improve 1.5～4 times, and performances such as aging resistance, adhesive property and tapping property all are superior to aluminium section bar solar cell frame.
