Description of drawings
Fig. 1 shows the employed half tone of embodiment of the invention printing solar cell.
Fig. 2 A to 2B shows the rearview of embodiment of the invention solar cell substrate.
Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention; Below in conjunction with accompanying drawing and preferred embodiment; The solar cell that proposes according to the present invention is printed embodiment, structure, characteristic and the effect of the method for identification code, specify as after.
In the solar cell processing procedure, one batch of solar cell substrate can form electrode at the solar base plate extinction face and the back side after in regular turn through cleaning, structuring (texturing), diffusion, insulation and coating anti reflection layer, connect extraneous circuit.Please see figures.1.and.2 simultaneously; The invention is characterized in; Metal paste is formed first bus 21 (rear side bus bar) and second bus 22 with the back side 20 that the wire mark mode is printed on solar cell substrate 2, and also the identification code 23 with an identification wafer is printed on the solar cell substrate 2.
Fig. 1 prints first bus 21, second bus 22 and identification code 23 employed half tones 1 on solar cell substrate.By finding out among the figure, except the pattern openings 12 of the pattern openings 11 that defines first bus 21, second bus 22, also defined the pattern openings 13 of identification code 23 on the half tone 1.As can be seen from the surface, the first bus 21 and the second bus 22 to the pattern of openings 11 and 12 form two rows of openings fair.
The pattern openings 11,12 of first bus 21 and second bus 22 also is divided into three zones with half tone 1.The upper area of the pattern openings 11 of first bus 21 be first area 101, the first buses 11 and second bus 22 pattern openings 11, be that the lower zone of the pattern openings 12 of second area 102, the second buses 22 is the 3rd zone 103 between 12.
The first and the 3rd zone 101,103 can be according to demand, selected arbitrarily units zone or the tens zone represented.For example in the embodiment of the invention,, represent tens zone and units zone respectively with first area 101 and the 3rd zone 103.Yet the identification of identification code 23 tens and units in fact also can be selected different differentiating methods according to demand.
It should be noted that; Please with reference to Fig. 2; For in the wire mark processing procedure, scraper plate is just advanced once and can first bus 21, second bus 22 and identification code 23 all be printed on the solar cell substrate back side 20 to a direction, reaches the purpose of saving the processing procedure time; The embodiment of the invention mainly is through changing the position of scraper plate starting point and terminal point, giving different chips other identification code 23.So, in the embodiment of the invention, the opening 13 that only the 101 and the 3rd zone 103 is provided with the identification code pattern in the first area.
Identification code pattern openings 13 can be selected from wherein a kind of of group that graphic sign, figure notation, literal and combination in any thereof form.Graphic sign can be any geometries such as circular, square or triangle.In addition, also can use Arabic numerals or Roman number, perhaps adopt one, two, three ... And so on literal numbering.
The pattern openings 13 of the identification code 23 of present embodiment comprises a plurality of pictorial symbolizations 130 and numeric character 132; The user can be according to the numbering of each wafer; Be selected from the opening 132 that sees through pictorial symbolization 130, numeric character 132, the control scraper plate changes the position of Origin And Destination.By seeing on the drawing, scraper plate (or in the opposite direction) is from top to bottom advanced once, can the metal paste of first bus 21, second bus 22 and identification code 23 be printed on the solar cell substrate back side 20.
Fig. 2 A has shown the dorsal view of the solar base plate 2 of different sheets in the embodiment of the invention with Fig. 2 B.When utilizing half tone 1; When the control scraper plate is printed on the solar cell substrate back side 20 with metal paste from top to bottom; Promptly to represent tens be 9 if start position be " 9 " (printing out " 9 " in the first area 101 and the graphic sign of going together); And the terminal point of scraper plate motion during for " 9 " (print out in the 3rd zone 103 " 9 " with go together graphic sign), promptly representing units is 9.In other words, the wafer identification sign indicating number 23 of this sheet solar cell substrate 2 is " 99 ", shown in Fig. 2 A.
The rest may be inferred, and when the identification code 23 of a slice solar cell substrate 2 was " 98 " under printing, scraper plate was the starting point setting in motion with " 9 " in the zone 101 of half tone 1, and the destination county up to " 8 " in zone 103 stops, shown in Fig. 2 B.In other words, during wire mark,, can arrange out the situation of identification code from 99 ~ 00 through the Origin And Destination position of control scraper plate motion.Utilize method provided by the present invention, can number at least 100 solar cell substrate 2.Therefore, when carrying out the solar cell processing procedure, enough make each sheet solar cell all have its identification code 23 separately with a collection of solar cell substrate 2.
Certainly, in another embodiment, also can represent the identification code numbering with numeral merely.For example, it is starting point that scraper plate is selected a numeric character a from this tens zone, and when marching to the units zone, selecting another numeric character b is terminal point, and a and b represent 0 ~ 9 wherein arbitrary numeral, and then identification code is " ab " by interpretation promptly
Though be to write identification code in the embodiment of the invention with the decimal system, be not limited in this example, with other mode, for example octadic or hexadecimal also are fine.In addition, also can utilize the different patterns mark to distinguish tens and units, for example, the graphic sign of representing tens is square, and represents the graphic sign of units to use circular.
Because in the wire mark process, pictorial symbolization, literal or the numeral that identification code 13 may take place not seal is complete and cause erroneous judgement.Therefore, another kind of mode is with the foundation of the distance between graphic sign and the datum line as read-write.
In first area 101, set first datum line 1010, and the graphic sign in the first area 101 and the distance of first datum line 1010 are dA, promptly equal A unit distance, in the embodiment of the invention, first datum line 1010 is the edge of first bus 11.
In the 3rd zone 103, set second datum line 1030, be the border of solar cell substrate 2, and be positioned at the 3rd regional 103 graphic sign, with second datum line 1030 unit number apart be B, then the interpretation mode of identification code is " (A-1) (B-1) ".For example, among Fig. 2 A, A=10 is so the identification code 23 of B=10 this film solar cell substrate is " 99 ".In embodiments of the present invention, the identification code 23 of solar cell substrate 2 all is to come interpretation with the pattern recognition machine.
The composition of printing the metal paste of first bus 11, second bus 12 and identification code 13 comprises conductive metal powder, glass (pottery) powder and organic compound.Conductive metal powder can be selected from silver, aluminium, copper, silicon etc.Glass (pottery) powder helps slurry whole sintering and tack like PbO, B2O3, SiO2 etc.Organic compound then helps making metal paste to be printed on the solar cell substrate surface.
After the wire mark program; Also need pass through sintering processes again; Also be about to solar cell substrate 1 and be positioned in the annealing boiler tube, be heated to about 700 ~ 800 ℃, make metal diffusing to the solar cell substrate 2 of first bus 21, second bus 22 form good nurse contact difficult to understand with as electrode.
The present invention in fact also provides a kind of process parameter to batch solar cell substrate to increase the method for record relative position parameter.In the processing procedure process; Though the process parameter of same batch of solar cell is identical; But; During at the phosphorous diffusion processing procedure or with electricity slurry coating anti reflection rete, because the location parameter that solar cell substrate is placed difference to some extent, also possibly be one of the reason that causes the difference of solar cell usefulness.
Past is not owing to number the individual slices solar cell; Be difficult to analyze owing to the different differences that cause in position; Use method of the present invention to after the individual slices solar cell numbering; Before effect test, can write down the process parameter and the identification code of this batch solar cell through the solar cell after the sintering processes earlier.In case when finding that the usefulness of solar cell is not so good as expection, can see through the processing procedure experience that identification code is grasped this sheet solar cell, follow the trail of the reason of usefulness reduction, and adjust process parameter in good time to improve the usefulness and the quality of solar cell.
Certainly, imprinting identification code also can be applied to other pattern printing process on solar cell substrate.As: with the wire mark mode etching formula slurry (etch paste) or implanted slurry (doped paste) are printed in solar base plate, simultaneously with the identification code imprinting on solar cell substrate, also be feasible mode.
In sum, a kind of printing identification code provided by the present invention (identification) has advantage in method and the application of solar cell (solar cell):
(1) processing procedure is easy, and need not increase equipment cost.The method of printing identification code provided by the present invention may be incorporated in the original wire mark processing procedure of solar cell, and the process of printing identification code does not need complicated technology yet.If in the picture semiconductor integrated circuit processing procedure, the mode that adopts laser to scan is come each sheet solar cell substrate imprinting identification code, the cost of equipment is increased.But, adopt method of the present invention, then need pay the additional apparatus cost hardly.
(2) the process parameter correction is easier.Because each sheet solar cell substrate all has identification code separately, make that the parameter of each sheet solar cell substrate in the preparation process can be by record and build file.When the yield of solar cell descended, the testing staff can be according to the process parameter data of each sheet solar cell substrate, analyzed and searched problem, and adjust process parameter in good time, made the best in qualityization of solar cell.
The above only is embodiments of the invention, is not the present invention is done any pro forma restriction; Though the present invention discloses as above with embodiment; Yet be not in order to limiting the present invention, anyly be familiar with the professional and technical personnel, in not breaking away from technical scheme scope of the present invention; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
