Description
Technical Field
The invention relates to a preparation method of a non-net-knot screen printing plate.
Background
Finger electrode (finger) printing is required in the solar cell preparation process, and screen printing is required in the printing process. Most of the existing screen printing plate is made by covering a screen cloth with a high polymer material, and patterns are made on the material according to the requirements of customers. The straightness of the mesh cloth is insufficient due to factors such as tension when the mesh is stretched. The non-mesh screen printing plate must be subjected to scanning plate making in order to avoid mesh knots, and after the plate making is completed, the straightness of finger electrodes (fingers) is limited by the mesh cloth.
The size of the non-mesh screen is limited by the mesh cloth, so the finger electrode (finger) direction of each screen has uniqueness, and the uniqueness limits the application area of the screen, such as the SE solar cell manufacturing process. The SE solar cell process requires high concentration doping of the silicon wafer at and near the contact location of the finger electrodes (fingers), which limits the possibility of mass production if the finger electrode (finger) orientation is unique.
Disclosure of Invention
The invention aims to provide a method for preparing a net-knot-free screen printing plate.
In order to achieve the purpose, the invention provides a preparation method of a non-mesh screen printing plate, which comprises the following steps:
1) judging the trend of the screen cloth on the screen printing plate in a scanning mode or a tracing mode;
2) chemically or physically treating the steel wire which will be seated in the region of the finger electrode (finger); the treatment process comprises the following steps: firstly, judging a Y-direction steel wire which is located in a finger electrode (finger) area; then avoiding the steel wire in the X direction and clearing the steel wire in the Y direction in the finger electrode (finger) area;
3) and making the subsequent empty net according to a normal process.
Preferably, in step 2), the chemical method is etching, electrolysis or laser.
Preferably, in step 2), the physical mode is a stress shear mode.
Preferably, in step 2), a scanning method is adopted to avoid the steel wires in the X direction, and a protective layer pattern is formed on the mesh cloth, and then the mesh cloth is processed in a dry etching, wet etching or electrolysis manner.
Preferably, in step 2), the steel wire is directly processed by stress shearing, laser melting and the like in a tracing way without the X direction.
The invention has the advantages and beneficial effects that: the invention provides a method for preparing a net-knot-free screen printing plate.
As the market occupation rate of the single crystal SE process is gradually expanded, the scanning screen plate without the net junction is gradually eliminated and replaced by the screen plate with high number of fine wire diameters. The invention still uses the screen printing plate without the net knots as the preferred scheme of fine line printing at the present stage, can overcome the problems and match with the customer process, and still can optimistically expect that the net knots can occupy a place in the future high-efficiency battery plate market.
The invention has the following characteristics:
(1) the mesh cloth is pretreated in the invention, and the size of the silicon wafer doping area in the SE process can be matched;
(2) the screen printing plate without the mesh junctions is suitable for preparing high-efficiency solar cells.
