Description
Technical field
The invention belongs to the solar cell printing technology, relate in particular to a kind of method for designing of double-deck solar energy screen printing anchor point.
Background technology
The development of solar battery technology is more and more faster, although the relatively traditional forms of electricity generation such as firepower of its cost will exceed much at present, in the 21 century of advocating energetically low-carbon economy, the research of solar battery technology will be energy research one, field key player.
As the important step that crystal silicon cell is made, the printing quality of electrode of solar battery printing has very large impact to the performance of final cell piece.And the factor that affects printing quality is except the destabilizing factor that printing machine exists, and the performance of Printing screen and printing process have also had a strong impact on final printing quality.The research of solar cell has obtained very large development in recent years, in order to improve the transformation efficiency of solar battery sheet, reduce the contact resistance of positive electrode, and a kind of positive electrode carries out in the field of business the coming into vogue of method of twice double exposure.But can there be following problem in twice double exposure: dislocation appears in the second impression and the first impression, and the width of thin grid line increases, and increases and highly there is no obviously.The consequence that double exposure like this brings is that the depth-width ratio of thin grid line does not increase, and makes on the contrary the illuminating area of accepting of cell piece reduce, and the cell piece transformation efficiency reduces; Simultaneously, twice double exposure also can increase printing cost.
In order to reach higher double exposure effect, industry is also more and more higher to the requirement of printing technology, and the target of twice printing contraposition Deviation Control in the 1um scope proposed new challenge to industry.So it is particularly important that the design of anchor point becomes, can be accurately with Printing screen and solar cell substrates contraposition when the effect of anchor point is printing, when preventing from printing, the silver slurry is not printed onto on cell substrate, and can carry out secondary or the printing more than secondary to cell substrate easily, and secondary or the generation of the above printing of secondary dislocation-free situation.Secondary printing can improve the height of silver slurry, if but secondary printing contraposition words accurately, being prone to the silver slurry highly increases, and width increases.Like this, solar conversion efficiency step-down.At present, just there is such situation in many solar cell substrates printings.Provide a kind of technical scheme so need badly to study to develop, to solve the defective that exists in above-mentioned prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of method for designing of double-deck solar energy screen printing anchor point.
For achieving the above object, technical scheme of the present invention is:
A kind of method for designing of double-deck solar energy screen printing anchor point comprises the steps:
Make the ground floor web plate: adopt etching, laser cutting or electroforming process to make the first layer metal web plate, do not make anchor point when making the first layer metal web plate;
Blasting treatment is carried out on the locating point position surface: after the ground floor web plate is made, blasting treatment is carried out on the locating point position surface;
Pad pasting, exposure, development: before electroforming second layer web plate, stick one deck light-sensitive surface on the first layer metal web plate, on the position of anchor point appointment, according to the marker graphic of appointment, dry film is exposed, develops;
Electroforming second layer web plate, the upper strata of formation web plate: the web plate after exposure imaging is carried out electrotyping forming, form the upper strata of web plate; Wherein, the second layer metal web plate after electroforming forms the hole of a hollow out in exposure place, and the first layer metal web plate to place that should the position is being not perforate, and the locating hole contrast of formation is clear like this, and positioning accuracy is accurate.
Further, described blasting treatment needs and locating point position all can be covered.
Further, the shape of described anchor point can be any shape, is dispersed in web plate working region periphery.
Further, described anchor point is four and is shaped as circular anchor points, and symmetry is scattered in web plate working region surrounding.
It is simpler that the present invention makes the method that the method for anchor point compares in the past, and the exposure that only needs when exposure assigned address to be carried out designated shape can be completed.And the locating point position that this preparation method forms is accurate, easy to identify, can not occur CCD contraposition crawl less than situation.

The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Please refer to shown in Figure 1ly, the scheme that the method for designing of the double-deck solar energy screen printing of the present invention anchor point is based on the double layer of metal web plate designs, and described metal can be any metal material, comprises stainless steel, nickel metal, nickel-base alloy etc.It comprises the steps:
Make the ground floor web plate: adopt the techniques such as etching, laser cutting or electroforming to make the first layer metal web plate, do not make anchor point when making the first layer metal mask plate;
Blasting treatment is carried out on the locating point position surface: after the ground floor web plate is made, blasting treatment is carried out on the locating point position surface, wherein, how accurate it is that this surface sand-blasting positional precision does not need, and only needs sandblast locating point position all can be covered and get final product;
Pad pasting, exposure, development: before electroforming second layer web plate, stick one deck light-sensitive surface on the first layer metal web plate, on the position of anchor point appointment, marker graphic according to appointment exposes, develops dry film, wherein the shape of anchor point can be any shape, is dispersed in web plate working region periphery;
Electroforming second layer web plate, the upper strata of formation web plate: the web plate after exposure imaging is carried out electrotyping forming, form the upper strata of web plate.
Second layer metal web plate after electroforming forms the hole of a hollow out in exposure place, and the first layer metal web plate to place that should the position is being not perforate.The double layer of metal web plate is done as a whole, and anchor point can be regarded half punctum as, and namely the plate face has the hole of not opening at the place, location, because sandblast is arranged at the bottom, and surface-brightening, the locating hole contrast that forms like this is clear, and positioning accuracy is accurate.
