Description
(1) technical field:
The present invention relates to a kind of method for producing solar cell assembly.Relate to the solar-photovoltaic technology field.
(2) background technology:
The monomer solar cell is made by silicon single crystal or polycrystalline material, because it is thin and crisp, the electrode that can not stand more energetically bump, solar cell can not expose for a long time and use and reason such as the operating voltage of monomer solar cell is low, need some monomer solar cell series and parallels to be connected and tightly be packaged into solar module, just can make it to become the independent minimum unit that uses as power supply of an energy.
To the requirement of solar module can reduce following some: certain nominal operation voltage is arranged and certain nominal power output is arranged; Long working life; Enough mechanical strengths are arranged; The electrical property loss that combination causes is little; The combination cost is little.
The manufacture method of existing solar module is mostly as follows:
1. with the interconnector for preparing several solar is welded as a whole
2. crystal-silicon solar cell array, ethylene-vinyl acetate material (EVA), the compound fluoroplastics film (TPT) that forms with glass, ethylene-vinyl acetate material, through connection in series-parallel from bottom to top is superimposed together and puts into vacuum laminator
3. adopt the vacuum layer platen press that the laminating machine lower chambers is vacuumized, pressurized, heated is hot-pressed onto glass/EVA/ solar battery string/EVA/TPT together, takes out after the moulding
4. install frame additional, make solar module.
In the above-mentioned manufacture method of solar module, welding procedure is very important, and its reliability directly influences power output, working life and the mechanical strength of assembly.
In the prior art, the welding of solar battery sheet (being the welding of interconnector) generally is to adopt the common electrical flatiron, from top to bottom being coated with on the main grid line that the tin copper strips is welded in positive and negative electrode respectively of certain specification is being got final product on the workbench.There are the following problems for prior art: weld motionlessly sometimes, cross weldering sometimes, in addition, cause rosin joint, tin sweat(ing), the battery sheet main grid line phenomenons such as aliquation, solder joint height that come off easily, the flowability of scolding tin is poor simultaneously, and soldering reliability is poor; Welding back flat appearance degree is poor, brightness is poor, and easily aliquation, silver layer easily come off; The breakage rate height of welding back product; Also the power output of display module is undesirable to the detection of welding the back finished product.In a word, the performance of solar module is undesirable.
(3) summary of the invention:
The present invention aims to provide the comparatively ideal method for producing solar cell assembly of a kind of performance.
Technical solution of the present invention is as follows:
A kind of method for producing solar cell assembly comprises the steps:
