Abstract

The invention discloses a solar cell piece electroplating pattern screen printing plate. The solar cell piece electroplating pattern screen printing plate comprises a net frame and a polyester silk screen, wherein the polyester silk screen is arranged on the net frame in a stretching mode, a silk screen hole is formed in the center of the polyester silk screen, a stainless steel wire mesh covers the silk screen hole, the connecting position between the stainless steel wire mesh and the polyester silk screen is bonded by a hot melt adhesive, an electroplating layer is arranged on the stainlesssteel wire mesh, a nickel electroplating layer is arranged on the surface of the electroplating layer, a plurality of wire grooves are formed in the electroplating layer, the wire grooves form a printing pattern, and the stainless steel wire mesh is provided with a printing surface and an ink scraping surface. The invention further discloses an electroplating graph manufacturing method of the solar cell piece electroplating pattern screen printing plate. The manufacturing method is simple in manufacturing process and low in dependence on operators, product instability caused by human factors is avoided, the yield of a screen printing plate is improved, the production cost is reduced, the surface of the manufactured screen printing plate is smooth and has ultrahigh resolution, ultrahigh inkpermeability and high abrasive resistance, and the service life of the screen printing plate is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of solar cell screen printing, in particular to a solar cell electroplating pattern screen plate and a method for making the electroplating pattern. Background technique [0002] Existing screens for solar crystalline silicon cell printing use diazo-type photosensitive materials for all their graphic parts. After ultraviolet exposure and development, during the exposure process, the chemical molecular structure of the photosensitive material changes in the part irradiated by ultraviolet rays. It is water-soluble, but the part blocked by the film negative is not irradiated by ultraviolet rays, and still has the super water-solubility of the material itself. After the exposed screen is washed with water, it forms a "yin and yang diagram" to form a graphic that can be printed. Effect. However, the existing screen plate for printing crystalline silicon solar cells has a complex and numerous plate-making process...
