Background technology
At present, solar energy production enterprise often is sent to authoritative institution with the solar battery sheet of its production and goes to demarcate (generally will demarcate parameters such as electric current), demarcates the testing standard of back as the production equipment of this enterprise; So being referred to as the solar cell demarcation, said solar battery sheet (being generally crystal silicon solar cell sheet) uses standard film; Being shaped as of said solar battery sheet is square, and respectively there is an electrode its surperficial length direction both sides, and the length of electrode is identical with the width of solar battery sheet; Electrode is generally formed by silver slurry printing back sintering; Electrode interior is the rarefaction of porous, and the height of electrode is 0.1 ~ 0.2mm, and the abrasion resistance properties of electrode is poor.
Before producing every day, enterprise all need adopt solar cell to demarcate and with standard film its production equipment tested.During test, need two row's metallic test probes are pressed in respectively on two electrodes.Because the solar cell demarcation is many with the access times of standard film, frequency of utilization is high; After repeatedly using; The pressure of test probe can cause the respective electrode on the solar battery sheet to damage; Serious even cause that solar battery sheet is latent to be split, these all make the performance of solar battery sheet own change, cause solar cell demarcate with standard film lost efficacy, useful life is shorter.
The utility model content
The utility model technical problem to be solved provides a kind of solar cell demarcation permanently effective, that useful life is long and uses standard film.
For solving the problems of the technologies described above; The utility model provides a kind of solar cell to demarcate and has used standard film; It comprises square metal base plate, three length and corresponding identical highly respectively square solar battery sheet, two flexible insulation bars, two metal beads; Three solar battery sheets stick on the backplate surface through conducting resinl and the three along the length direction each interval of base plate; The Width of each solar battery sheet and the length direction of base plate are same trend, and the length direction of each solar battery sheet and the Width of base plate are same trend, all fill an insulation strip in the gap between per two adjacent solar battery sheets; And height such as this insulation strip and solar battery sheet; On the surface of per two adjacent solar battery sheets corresponding to corresponding gap location all through press strip of conductive adhesive, and the width of this press strip is greater than the width of said respective clearance, the height of two press strips is 0.1 ~ 0.2mm.
For the purpose of the concise description problem, below the said solar cell of the utility model demarcated all abbreviate this standard film as with standard film.
Need to prove; After three solar battery sheets are pasted through conducting resinl and backplate surface; Control and make two gaps between three solar battery sheets demarcate correspondingly on the position with two electrodes on the standard film with existing solar cell respectively, two press strips become two electrodes in this standard film.
Before producing every day, enterprise adopts this standard film that its production equipment is tested.During test, two row's test probes are pressed in respectively on two press strips.
The material of two press strips of cause is the higher metal of hardness; Compare with the electrode in the standard film with existing solar cell demarcation; Its abrasion resistance properties is very strong; So even the access times of this standard film are many, frequency of utilization is high, the pressure of test probe can not cause respective compression beads to damage yet, and can guarantee that still test probe well contacts with respective compression beads (being electrode); Because of the press strip below is followed successively by flexible insulation bar, base plate, there is not solar battery sheet, so even the access times of this standard film are many, frequency of utilization is high, the pressure of test probe can not cause the latent of solar battery sheet to split yet, solar battery sheet can not sustain damage.These make that all the property retention of solar battery sheet own is constant.
In sum; Even enterprise all adopts this standard film that its production equipment is tested every day; Also can avoid respective compression beads and solar battery sheet in this standard film of test probe damage; And guarantee that test probe well contacts with the interior respective compression beads of this standard film, so that this standard film is permanently effective, useful life is longer.
The width of said two solar battery sheets that are positioned at floor length direction both sides is identical and be set at A; The width that setting is positioned at that solar battery sheet in zone, floor length direction stage casing is B; B＞A, and two gaps between three solar battery sheets are corresponding identical respectively on length and width;
The length of the length of the width of base plate, two insulation strip, two press strips all length with solar battery sheet is identical;
The area sum of three solar battery sheets and two insulation strip equals the area of base plate.
The material of said base plate, press strip is copper material.
Description of drawings
Fig. 1 is the stereogram of this standard film.
Embodiment
To combine accompanying drawing that the execution mode of the utility model is specifically described below:
Referring to Fig. 1; This standard film comprises square metal base plate 1, three length and corresponding identical highly respectively square solar battery sheet 2, two flexible insulation bars 3, two metal beads 4; Three solar battery sheets 2 stick on the surface of base plate 1 through conducting resinl and the three along the length direction of base plate 1 equi-spaced apart each other; The length direction of the Width of each solar battery sheet 2 and base plate 1 is same trend; The Width of the length direction of each solar battery sheet 2 and base plate 1 is same trend; All fill an insulation strip 3 in the gap 5 between per two adjacent solar battery sheets 2, and this insulation strip 3 and solar battery sheet 2 height such as grade, on the surface of per two adjacent solar battery sheets 2 corresponding to 5 places, gap accordingly all through press strip 4 of conductive adhesive; And the width of this press strip 4 is greater than the width of said respective clearance 5, and the height of two press strips 4 is 0.2mm.
