Abstract
The invention discloses a method for removing foreign matters on a light receiving face of a solar assembly, in particular to a method for removing the foreign matters on the light receiving face of the solar assembly by using a mixed chemical reagent and belonging to the technical field of production of solar batteries. In a technical scheme, the method comprises the steps of: firstly, processing the foreign matters on the light receiving face of the solar assembly by using the mixed chemical reagent, then scraping the foreign matters by using a blunt object, and finally cleaning the surface of the solar assembly completely. Compared with a method for scraping the foreign matters by using a sharp cutter, the method disclosed by the invention can be used for cleaning a large area of residual foreign matters without residues and simultaneously has the advantages of being simple to operate, having no damage to the surface of the assembly through scraping, preventing the light receiving face of the solar assembly from being reduced, improving the product appearance of the solar assembly, preventing the light receiving face of the assembly from area loss and reducing the rejection rate. According to the invention, based on the theory that like dissolves like and specific to the self chemical composition of the foreign matters on the light receiving face, solidified epoxy foreign matters are swelled by using the mixed chemical reagent so as to destroy the binding force between the foreign matters and glass, and the foreign matters can be easily removed after being softened.
Description
Technical field
The present invention relates to a kind of method of removing solar components sensitive surface foreign matter, particularly remove the method for solar components sensitive surface foreign matter, belong to the manufacture of solar cells technical field with mixed chemical reagent.
Background technology
In the solar cell actual production process, because unit exception or personnel operation error cause solar components sensitive surface retained foreign body.These foreign matters have a strong impact on assembly finished product outward appearance, and the assembly light-receiving area is reduced, and cause and scrap.Common treating method is to utilize sharp-pointed cutter to strike off, but these foreign matters are very hard, and bonding very firm with sensitive surface.Use cutter to strike off and generally can only remove the very foreign matter of small size, this operation simultaneously may cause assembly by scratch and potential safety hazard.The solar module retained foreign body is generally macromolecular compound; Have good heat endurance and solvent resistance; Adopt the method for common chemical solvent or heating to be difficult to, so need to adopt special mixed chemical reagent just might to remove by solar components sensitive surface assembly retained foreign body with its dissolving or swelling.
Summary of the invention
The purpose of this invention is to provide a kind of method of removing solar components sensitive surface foreign matter, improve solar components finished product outward appearance, avoid assembly sensitive surface space wastage, reduce scrappage, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of method of removing solar components sensitive surface foreign matter, use mixed chemical agent treated solar components sensitive surface foreign matter earlier, and use blunt to strike off then, at last that removing surface is clean.
Said mixed chemical reagent is that epoxy resin removes agent.
Use earlier the mixed chemical solvent with solar components sensitive surface foreign matter impregnation process 10 minutes～300 minutes, use blunt to strike off then.Described impregnation process is: the non-dust cloth that will be impregnated with mixed chemical reagent applies on solar components sensitive surface foreign matter, makes its sealing with plastic film then.Described blunt comprises that plank or plastic plate scrape etc.
Said solar components is that crystal silicon solar energy battery, thin-film solar cells and/or employing glass are the organic dyestuff battery of sensitive surface, and wherein crystal silicon solar energy battery comprises: monocrystalline silicon battery and polycrystal silicon cell; Thin-film solar cells comprises: amorphous silicon, cadmium sulfide, cadmium telluride, copper indium tin, copper indium gallium tin thin film solar cell;
Said solar components sensitive surface foreign matter is epoxies conductive silver glue, silver slurry, titanium white powder printing ink and/or casting glue.
Good effect of the present invention: the inventive method is struck off with the sharp-pointed cutter of common use and is compared; Can clear up large-area retained foreign body and noresidue, simultaneously simple to operate, can the scratch assembly surface; Avoid reducing of solar components sensitive surface; Improve solar components finished product outward appearance, avoid assembly sensitive surface space wastage, reduce scrappage; The present invention is according to the similar principle that mixes, and to self chemical composition of sensitive surface foreign matter, utilizes the epoxies foreign matter swelling after mixed chemical reagent makes curing, destroys the adhesion of itself and glass, treat its deliquescing after, can easily remove.
