Abstract
Disclosed are a method of preparing CI(G)S nano particles forming a light absorption layer of solar cells, including dissolving at least one Group VI source selected from the group consisting of compounds comprising sulfur (S), selenium (Se), or a combination thereof, and an indium (In) salt in a solvent to prepare a first solution, reacting the first solution to form first precursor particles, dissolving a copper (Cu) salt in a solvent to prepare a second solution, mixing the second solution with the first solution in which the first precursor is formed to manufacture a mixture and purifying the synthesized CI(G)S nano particles after synthesizing the CI(G)S nano particles by reacting the mixture, and CI(G)S nano particles manufactured using the same.
