Title:
METHOD FOR MANUFACTURING METAL NANOPARTICLES FOR SOLAR CELL, INK COMPOSITION COMPRISING METAL NANOPARTICLES, AND METHOD FOR FORMING THIN FILM USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/119868
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing metal nanoparticles for a solar cell, an ink composition comprising the metal nanoparticles, and a method for forming a thin film using the same. More specifically, the present invention relates to a method for manufacturing metal nanoparticles, an ink composition comprising the metal nanoparticles, and a method for forming a thin film using the same, wherein the method for manufacturing metal nanoparticles, as a method for manufacturing metal nanoparticles forming a light absorbing layer, comprises the steps of: preparing a first solution containing a reducing agent; preparing a second solution containing at least two salts selected from the group consisting of a copper (Cu) salt, a zinc (Zn) salt, and a tin (Sn) salt; preparing a mixture by mixing the first solution and the second solution; and synthesizing at least one kind of metal nanoparticles through a reaction of the mixture, followed by purification.
