Description
Technical field
The present invention relates to a kind of application of solar energy, especially relate to a kind of folding thin-film solar charger.
Background technology
Solar energy is a kind of reproducible new forms of energy totally, is more and more subject to the favor of people.Be widely used in the life, work of people, solar energy is converted to electric energy by exactly, and solar cell utilizes the sun workable exactly.
Solar charger is after being electric energy by transform light energy, by electrical power storage in the battery of mobile device.Mobile device battery can be any type of electrical storage device, is mainly lead-acid battery, lithium battery, Ni-MH battery etc., and load can be the products such as mobile phone, satellite phone, MP3, intercom, notebook.
Solar charger in existing technology is battery component mainly with monocrystalline silicon or polysilicon, but the battery of crystal silicon is more crisp and need rigid material to protect it.Therefore the battery of crystal silicon is all thicker when reality uses, and weight is comparatively large, and can not bend, and therefore its portability just cannot embody.
Now consider to adopt CIGS solar film battery, be made up of the chalcopyrite crystalline membrane solar cell of optimal proportion Cu (copper), In (indium), Ga (gallium), Se (selenium) four kinds of elements.Due to this product, to have light absorpting ability strong, power generation stability is good, transformation efficiency is high, long, the many advantages such as energy output is high, production cost is low and the energy recovery cycle is short of generating dutation on daytime, CIGS solar cell has been the rising star of solar battery product, can contend with traditional crystal silicon solar batteries.In addition, CIGS solar film battery has lightweight, and volume is thin, and can the bending feature of appropriateness, therefore has good portability, is suitable for people and carries.But the water resistance of the solar charger using now CIGS to make is poor, and CIGS is after making moist, and its energy conversion rate will significantly decline, and useful life reduces.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of folding thin-film solar charger, has good water resistance, high life.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of folding thin-film solar charger, comprise collapsible brace and polylith CIGS cell piece, described polylith CIGS cell piece is fixed on the surface of collapsible brace after connecting successively, described collapsible brace is provided with charging inlet, described charging inlet is connected with CIGS cell piece, the outer surface of described CIGS cell piece is coated with a PO glued membrane from outside to inside successively, first blocks water film, first EVA adhesive film and an ETFE glued membrane, the lower surface of described CIGS cell piece is coated with back of the body cloth.
Also be provided with the 2nd PO glued membrane, second between described back of the body cloth and collapsible brace to block water film and the second EVA adhesive film, the 2nd described PO glued membrane covers the lower surface of back of the body cloth, second EVA adhesive film covers the upper surface of collapsible brace, and described second blocks water film between the second PO glued membrane and the second EVA adhesive film.Except carrying out the design that waterproof blocks water at the upper surface of CIGS cell piece, between the back side of CIGS cell piece and collapsible brace, take into account the process that a step is carried out waterproof and blocked water.Therefore between the back side of CIGS cell piece and collapsible brace, design the 2nd PO glued membrane, second to block water film and the second EVA adhesive film.Can ensure that the water resistance at the CIGS back side is good.
Described collapsible brace adopts cloth to make, and described second film that blocks water is transparent material.Collapsible brace uses cloth to make, and has done contraction and water-proofing treatment to cloth, and therefore cloth also has certain waterproof effect, and the cloth quality processed can consolidation more.Therefore the CIGS cell piece be arranged on collapsible brace can bend to a certain extent, and namely only has collapsible brace in the periphery of CIGS cell piece, can fold arbitrarily.
Described collapsible brace comprises multiple thin slice, between described multiple thin slices, left and right is connected, described thin slice is coated with CIGS cell piece, the thin slice being positioned at right side is corresponding with on the thin slice being positioned at left side is provided with double buckle, connects multiple thin slice and be folded into thin-slab structure by double buckle.The design of double buckle is convenient at non-working condition, the present invention is folded up and buckles well, and realizes carrying simply and easily.
The described thin slice being positioned at right side is provided with strip-type handle, and described strip-type handle is made up the middle part of the thin slice being positioned at right side of flexible material.The setting of strip-type handle is once convenient to user and is mentioned the present invention, is second easy to carry equally.
Joining place between two described thin slices is provided with the arc notch internally caved in.The edge of the collapsible brace after folding is round and smooth, attractive in appearance and safety, can not hurt because thin slice is too frivolous.
Described charging inlet is wrapped with shell body, is also provided with circuit board in described shell body, and described charging inlet is connected with CIGS cell piece by circuit board, and described charging inlet is USB interface.USB interface is a kind of interface the most frequently used in the charger of existing mobile device, to be connected by the interface on mobile device namely can to realize charging by a connecting line with charging inlet.
Compared with prior art, the invention has the advantages that surface CIGS cell piece being fixed on collapsible brace, collapsible brace contains multiple CIGS cell piece, achieves convenient portable, and has certain protective effect to CIGS cell piece.The outer surface of CIGS cell piece is coated with a PO glued membrane, first from outside to inside successively and blocks water film, the first EVA adhesive film and an ETFE glued membrane.
PO glued membrane is a thermo-compression bonding glued membrane for metal species.There is environment-protecting asepsis, wear-resisting, the resistance to complications of high resiliency tear-proof, hydrolysis, cold-resistant feature.The film that blocks water then has the effect of good stop moisture.The sticking glued membrane of a kind of thermosetting of EVA adhesive film, due to the superiority that EVA adhesive film has in adhesion strength, durability, optical characteristics etc., makes it be more and more widely used in current components and various optical articles.The high grade of transparency, high adhesion strength goes for various interface.Good durability can resist high temperature, moisture etc.Easy storage.Room temperature is deposited, and the adhesion strength of EVA is not subject to the impact of humidity and water absorption film.ETFE glued membrane is mainly used in flexible PCB and great power LED is produced and do release in electronic product production, and this glued membrane has the effect of very good isolation glue, does not stick together with any glue.But also have that ductility is good, high temperature resistant, tensile strength high.
So above-mentioned several films are covered in a certain order CIGS cell piece surface, can be good at moisture etc. being unfavorable for the material that CIGS cell piece is deposited is isolated outside, in addition the light transmission of above-mentioned several film is good, can't absorb solar energy impact CIGS cell piece.Present invention achieves good water resistance, ensure that energy conversion rate and the useful life of CIGS cell piece.
