    • The present invention provides a method for manufacturing an electrode for a solar cell, a substrate for the solar cell manufactured by the same, and a solar cell manufactured by the same. The present invention forms an electrode of a specific pattern through an offset printing system, and plates the electrode through a plating process to fill the metal-free region of a bus bar electrode with a plating metal and thus reduce the sheet resistance of the bus bar. The present invention obtains a finger electrode with a line with 100 microns or less through the combination of an offset printing process and a wet metal plating process. Further, the present invention obtains an electrode with an aspect ratio of 0.2 to 0.6 to reduce light shield effects and improve efficiency of the solar cell. The present invention eliminates the necessity of multilayer offset printing, and thus to reduce use of expensive conductive paste with might otherwise increase in proportion to the number of times printing is performed.
