Problems solved by technology

[0002] In recent years, with the continuous development of solar cell electrode silver paste printing technology, the industry has put forward higher technical requirements for the screen plate used for pure secondary line printing of solar cells in terms of aspect ratio after silver paste printing, but the existing The printing screen plate is a woven screen plate, which has the following defects: a. The woven screen plate has warp and weft nodes, which is easy to produce marks on the substrate; b. The woven screen plate is prone to dislocation of the mesh line during printing, which affects the graphics. Precise printing accuracy; c, the woven screen plate is not easy to control, and cannot achieve fine thick film printing

Embodiment Construction

[0023] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the composite metal steel sheet for pure secondary line printing of solar cells of the present invention includes a single-layer metal film 3 and a frame 1 for peripheral positioning. The protective effect of the metal film 3, the single-layer metal film body 3 is provided with several sub-wires 4 of the positive electrode of the solar cell, and the several sub-wires 4 are elongated and evenly distributed on the single-layer metal film body 3. The metal film 3 is processed by electroforming nickel alloy sheet, laser-cut stainless steel sheet or chemically etched metal sheet. It has the characteristics of high surface hardness, excellent brush resistance and solvent resistance. The single-layer metal film 3 The thickness is between 20 and 60 microns, and the thickness of the single-layer metal film 3 is t...

Abstract

The invention discloses a composite metal steel plate for solar battery pure subline printing. The composite metal steel plate comprises a single-layer metal film, wherein a plurality of sublines of a solar battery positive electrode are arranged on the single-layer metal film; and a plurality of the sublines are respectively of a strip shape and are uniformly distributed on the single-layer metal film. The composite metal steel plate for the solar battery pure subline printing in the invention can replace the original weaving silk screen plate printing, does not produce moulage on a printed object and meets super-elaborate requirement on printing; electrical performance of the solar battery positive electrode can be improved after silver paste printing so that the conversion efficiency of solar energy is improved; and the composite metal steel plate has the advantages of high hardness and good printing resistance and dissolve resistance, and has good application prospect.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a composite metal steel plate suitable for pure sub-line printing of solar cells. Background technique [0002] In recent years, with the continuous development of solar cell electrode silver paste printing technology, the industry has put forward higher technical requirements for the screen plate used for pure secondary line printing of solar cells in terms of aspect ratio after silver paste printing, but the existing The current printing screen is a woven screen, which has the following defects: a. The woven screen has warp and weft nodes, which are easy to produce marks on the substrate; b. The woven screen is easy to produce mesh line misalignment during printing, which affects the graphics. Precise printing accuracy; c. The woven screen plate is not easy to control, and fine thick film printing cannot be realized. Contents of the invention [0003] The purpose of the pr...
