Method for forming conductive electrode patterns and method for manufacturing solar cells comprising the same

摘要

A method for forming conductive electrode patterns of a solar cell is provided. The method includes preparing a glass substrate and forming a transparent conductive oxide film (TCO) on the glass substrate. Then, a titanium oxide (TiO2) layer and a silver (Ag) electrode are formed on the glass substrate. A nickel (Ni) layer is formed on the Ag electrode and a copper (Cu) layer is formed on the Ni layer. In addition, a tin (Sn) layer is formed on the Cu layer.

1. A method for manufacturing a solar cell having a different metal layer on a silver electrode as a conductive electrode, comprising:
preparing a glass substrate; forming a transparent conductive oxide film (TCO) on the glass substrate; forming an anti-plating layer on the transparent conductive oxide film (TCO) formed on the glass substrate; forming a silver (Ag) electrode between the areas of the anti-plating layer; forming a nickel (Ni) layer on the Ag electrode; forming a copper (Cu) layer on the Ni layer formed on the Ag electrode; forming a tin (Sn) layer on the Cu layer formed on the Ni layer formed on the Ag electrode; and removing the anti-plating layer, wherein the nickel layer formation includes forming a coating of the different metal using the Ag electrode as a seed, wherein the Ag electrode has a thickness of 1 to about 20 um, has a bell shape with a bulging upper portion, and is formed by a coating method selected from a group consisting of: screen printing, dispenser printing, ink jet printing, roll printing, gravure printing, and spin coating.
