Title:

SCREEN PRINTING PLATE FOR SOLAR CELL AND METHOD FOR PRINTING SOLAR CELL ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2012/105381

Kind Code:

A1

Abstract:

The present invention relates to screen printing plate for a solar cell in which an electroconductive paste is used to simultaneously print a bus bar electrode and a finger electrode, the screen printing plate characterized in that the opening width of a finger electrode opening of the screen printing plate is less than 80 μm and a bus bar electrode opening of the screen printing plate has a closed section. The use of this screen printing plate makes it possible to reduce the cost of manufacturing solar cells, prevent the connecting section between the bus bar electrode and the finger electrode from breaking without causing an increase in shadow loss or compromising the aesthetic quality of the solar cells, and manufacture highly reliable solar cells with good productivity.
