Abstract
The invention relates to a rework method of a thin-film solar cell assembly polyvinyl butyral (PVB) film, which belongs to the technical field of solar cell production. The technical scheme is that PVB film scraps are used for filling a contracted portion of the film solar cell assembly, then a heat gun is used for heating and melting the scraps so as to combine the scraps and the film solar cell assembly packaging materials, and processing is finished. Or the PVB film scraps are added in a hot melting gun so that after the PVB film scraps are heated and melted by using the hot melting gun, the hot melting gun is aligned to the contracted portion of the film solar cell assembly to conduct filling, melted PVB film scrap liquid is combined with the film solar cell assembly packaging material, and processing is finished. The rework method uses the scraps of the packaging material to fill and repair the contracted portion of the assembly, no additional cost is increased, simultaneously, the rework method is simple and fast and can meet strict requirements of people on solar assembly appearance.
Description
Technical field
The present invention relates to a kind of Thinfilm solar cell assembly PVB film reworking method, particularly, belong to the manufacture of solar cells technical field with heat gun or the method for hot melt rifle heating PVB film leftover pieces to contracting and do over again in the thin film solar assembly corner.
Background technology
In the solar cell actual production process,, contract in being commonly called as because error of unit exception, personnel operation or raw material cause solar components edge and bight in encapsulation process to produce the phenomenon that encapsulating material is retracted to component internal unusually.The phenomenon that contracts in the Thinfilm solar cell assembly corner has influenced the finished product outward appearance of assembly, makes steam invade inside battery under the serious situation easily and causes assembly to scrap.Common treating method is the degree that contracts according in the component package material, and the assembly that contracts slight in the encapsulating material is reduced product hierarchy, and the serious assembly that contracts in the encapsulating material is scrapped processing.Contracting in the component package material is that common packaging process is bad, greatly influences the product packaging yield, causes the tremendous economic loss.
Summary of the invention
The purpose of this invention is to provide a kind of Thinfilm solar cell assembly PVB film reworking method, improve solar components finished product outward appearance, avoid assembly encapsulation to occur and lost efficacy, reduce scrappage, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is:
A kind of Thinfilm solar cell assembly PVB film reworking method; Thinfilm solar cell assembly occurs contracting in the corner after the phenomenon; Use PVB film leftover pieces partially filled with what contract in the Thinfilm solar cell assembly; Use heat gun with the leftover pieces heating and melting then, itself and Thinfilm solar cell assembly encapsulating material are combined, accomplish and handle; Or with in the PVB film leftover pieces adding hot melt rifle; After making the hot melt rifle with PVB film leftover pieces heating and melting; The part that contracts in the alignment thin film solar module is filled; PVB film corner feed liquid body and Thinfilm solar cell assembly encapsulating material after the fusion are combined, accomplish and handle.
Said PVB film is the polyvinyl butyral film material, and wherein the polyvinyl butyral film material comprises: transparent/white PVB and other polyvinyl butyral resin thermoplasticity encapsulating material of deriving.
Said Thinfilm solar cell assembly is thin-film solar cells or organic dyestuff battery, and wherein thin-film solar cells comprises: thin-film solar cells such as silica-based, cadmium sulfide, cadmium telluride, copper indium tin, copper indium gallium tin.
Said PVB film leftover pieces are the identical waste material of PVB film condensation material that uses with Thinfilm solar cell assembly.
Good effect of the present invention: the PVB film is a thermoplastic macromolecule material; Heating and melting once more; Make Thinfilm solar cell assembly encapsulating material and leftover pieces fusion and be together with each other through heating means; The zone of contracting in the minimizing receives intrusion effects such as air, moisture, thereby improves the encapsulation performance of Thinfilm solar cell assembly, has improved the assembly outward appearance simultaneously.The present invention uses the leftover pieces of encapsulating material that the partially filled method for repairing and mending that contracts in the assembly is done over again, and does not have extra increase cost, and this rework operation method is simple, quick simultaneously, satisfies the strict demand of people to the solar components outward appearance.
Description of drawings
Fig. 1 is the embodiment of the invention 5, the Thinfilm solar cell assembly schematic appearance that contracts in the bight and be of a size of 6mm*9mm;
Fig. 2 is the embodiment of the invention 5, does over again and handles the angle schematic appearance that contracts in the solar module of back;
