Method for manufacturing anode screen plate for improving solar cell silicon sheet conversion rate

Abstract

The invention provides a method for manufacturing an anode screen plate for improving the solar cell silicon sheet conversion rate. The method comprises the following steps: 1, superposing and contrasting an anode printing figure and a screen plate figure by computer software; 2, adjusting the spacing between adjacent longitude wires on the fine grid wire part of the anode printing figure of a corresponding solar cell silicon sheet; 3, increasing the wire diameters of the longitude wires and latitude wires of the anode screen plate outside of the anode printing figure of the solar cell silicon sheet; and 4, completing the manufacturing of the screen plate through in an electroforming or micro-cutting manner according to the figure. The method solves a problem that the conversion rate of the solar cell silicon sheet cannot breakthrough because the printing of screen plates in the prior art is discontinuous and nonuniform, and the spacing between the adjacent longitude wires of the screen plate is adjusted to make the fine grid wire of the anode printing figure have no network nod blocks. The screen plate manufactured through adopting the method has the advantages of no discontinuity after the silver slurry printing, uniform printing, fine grid wire width, and improvement of the cell sheet conversion rate.

AI Technical Summary

Benefits of technology

This patented technology improves the quality of photovoltaic cells by optimizing their design for better performance compared to traditional methods like adding extra components or adjusting certain parameters such as light intensity levels.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance of solar cell devices made from crystalline silicon wafers for use on both terrestrial (Solar) power generation systems and space applications where high temperatures are present during operation. Specifically, there may occur issues when small particles called tiny cracks form along certain areas within these panels which can cause electrical shorts between different parts of the device's circuitry. These minute defects could affect its overall effectiveness and even result into failure if they were left unnoticeable after manufacturing.
