CONDUCTIVE PASTE FOR SOLAR CELL ELECTRODE, AND SOLAR CELL MANUFACTURED USING SAME

Title:

CONDUCTIVE PASTE FOR SOLAR CELL ELECTRODE, AND SOLAR CELL MANUFACTURED USING SAME

Document Type and Number:

WIPO Patent Application WO/2022/097839

Kind Code:

A1

Abstract:

The present invention can provide a conductive paste for a solar cell electrode, characterized by comprising: metal powders; a glass frit; an organic vehicle; and an additive, wherein the aspect ratio of silver crystals recrystallized during firing of the conductive paste is in an average range of 0.005 to 0.50, and thus, the conductive paste has the effect of improving efficiency by preventing leakage current due to recombination of electrons and holes during solar cell manufacturing.
