A kind of solar cell printing screen plate and plate making method thereof

Abstract

The invention discloses a solar cell printing screen screen plate and a plate-making method thereof, which comprises a screen body formed by interweaving warp threads and weft threads, the upper surface of the screen body is uniformly provided with a cured photosensitive adhesive layer, the The photosensitive adhesive layer is distributed with at least one row of rectangular through holes intermittently distributed along straight lines parallel to each other, the straight line of each row of rectangular through holes is parallel to the warp, and the rectangular through holes are on the screen body There is no intersection point between the projection and the warp line, because the rectangular through hole of the present invention is printed in parallel with the warp line, and there is no intersection point with the warp line, the rectangular through hole only intersects with the weft line, which greatly reduces the net knot and silk thread on the printed film. Blocking, increasing the amount of ink penetration, smooth lines after printing, and improving electrical performance conversion efficiency; and the screen of the present invention adopts the method of extracting the warp at the position of the rectangular through hole during plate making, which reduces the difficulty of plate making, facilitates production, and lower production costs. Low.

Description

technical field [0001] The invention relates to a solar cell printing screen screen plate and a plate making method thereof. Background technique [0002] The solar cell printing screen screen needs to coat a layer of photosensitive glue on the surface of the screen, and then use a light-shielding sheet with a long rectangular shading pattern to block the photosensitive glue layer for printing. The photosensitive glue hardens after being exposed to light, and is blocked. The living part is washed away by a high-pressure water gun, and a rectangular through hole is left on the photosensitive adhesive layer on the screen to complete the plate making. After the plate making, the screen can be used for printing solar panels. [0003] as attached figure 1 As shown, at present, in order to improve the success rate of printing and washing of the screen, most of the rectangular patterns on the shading sheet and the longitude and latitude of the screen present a certain angle, gener...

AI Technical Summary

Problems solved by technology

However, since the rectangular through holes intersect with the warp and weft of the screen at the same time, the warp and weft are easy to block printing during printing, and it is not easy to ink, which brings difficulties to printing.
