Abstract
Disclosed are a method of preparing metal nanoparticles for solar cells, an ink composition including the metal nanoparticles, and a method of preparing a thin film using the same. More particularly, there are provided a method of preparing metal nanoparticles for forming a light absorption layer of a solar cell, including preparing a first solution including a reducing agent, preparing a second solution including 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 by reaction of the mixture and purifying the synthesized metal nanoparticles, an ink composition including the metal nanoparticles, and a method of preparing a thin film using the same.
