Abstract
The invention discloses an SE (selective emitter) process convenient for printing alignment. At least two mark points are arranged on an SE figure during SE process. The mark points are added to the conventional SE figure to allow a metallized automatic aligner to grab the mark points so as to complete mechanical alignment, manual alignment is replaced, alignment precision is greatly improved, and cell efficiency is improved.
Description
Technical field
The present invention relates to a kind of selection emitter processing procedure of solar battery sheet, specifically a kind of SE processing procedure that makes things convenient for print register.
Background technology
SE(Selective Emitter, abbreviation SE) processing procedure is a critical processes of producing the high performance solar batteries sheet, mainly be under the front gate line of battery, heavily to spread, there is not the place of grid line to carry out shallow diffusion, after this processing procedure is finished, in metallization process, need grid line is registered to the zone of heavily spreading in the SE processing procedure.If grid line is printed on the heavy diffusion zone of SE very accurately, cell piece efficient will be greatly improved, and does not have to aim at, and the efficient of cell piece will reduce greatly.This alignment procedures generally is the artificial false sheet printing of using, and by means of visually observing fine setting, such accuracy is just not high.
Summary of the invention
Goal of the invention: be the deficiency that exists for prior art, the SE processing procedure that prints for convenient metallization auto-alignment in a kind of SE processing procedure be provided, thereby improved alignment precision and reduced cost.
Technical scheme: for achieving the above object, the invention provides a kind of SE processing procedure that makes things convenient for print register, the SE figure is provided with and is no less than two index point in the described SE processing procedure.Index point of the present invention is positioned at the discontinuities of main grid of grid line or the edge of thin grid.
The present invention has added index point at SE figure originally, so that the automatic calibration instrument in the metallization process can analyze by the crawl index point position of cell piece, thereby calculate correct printing position, so that metal grid lines can be printed on the heavy diffusion zone of SE accurately.The present invention increases any cost hardly, has but saved human cost and the false sheet cost of conventional manual-alignment, has increased alignment precision, and the quality of product is improved.
Beneficial effect: a kind of SE processing procedure that makes things convenient for print register of the present invention has the following advantages:
The present invention has only added index point at the SE of routine figure, and these signs can be metallized the automatic calibration instrument and are used for crawl, thereby replaces manual-alignment, greatly improves the precision of aiming at, and improves cell piece efficient.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is cell piece efficient comparison diagram in the embodiment of the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, present embodiment is implemented under take technical solution of the present invention as prerequisite, should understand these embodiment and only be used for explanation the present invention and be not used in and limit the scope of the invention.
Embodiment:
A kind of SE processing procedure that makes things convenient for print register, the SE figure is provided with four index point 3 in the SE processing procedure, and index point 3 is positioned at the edge (such as Fig. 1) of thin grid 2.
Present embodiment has added four index points on the SE of routine figure, these four index points can be metallized the automatic calibration instrument and be used for grasping, replace manual-alignment, greatly improve the precision of aiming at, improved cell piece efficient, drawn by experiment data (such as Fig. 2);
Auto in the data is the data of using certain metallization automatic calibration instrument to obtain, can see and using after the automatic calibration that the average efficiency of cell piece has improved 0.07%, mainly is that FF has improved 0.31%, and this gives the credit to the raising of alignment precision.
Claims (2)
