Title:
CONDUCTIVE PASTE FOR SOLAR CELL ELECTRODE AND SOLAR CELL MANUFACTURED USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/088521
Kind Code:
A1
Abstract:
The present invention relates to a conductive paste for a solar cell electrode, the conductive paste containing a metal powder, glass frit, an organic binder, and a solvent, wherein a surface of the metal powder is coated with an alkyl amine-based material having 6 to 24 carbon atoms. The surface of the metal powder is coated with a coating agent with low solubility, thereby stably realizing a fine line width of solar cell front electrodes, formed by using the conductive paste, and improving electrical characteristics of the electrodes, leading to an improvement in power generation efficiency of a solar cell.
