SYNTHETIC METHOD OF BINARY COMPOUND NANO PARTICLE, BINARY COMPOUND NANO INK USING THE SAME AND MANUFACTURING METHOD OF CIS THIN FILM SOLAR CELL USING THE SAME

摘要

The present invention provides a binary compound nano ink, which is formed by dispersing binary compound nanoparticles provided by using a synthetic method of the binary compound nano particles to isobutyl alcohol, and a manufacturing method of a CIS thin film solar cell by using the binary compound nano ink. The manufacturing method of binary compound nano particles comprises: a step of forming a compound by synthesizing and growing a chlorine-containing metal precursor solution and a selenium solution by using a reflux device at a predetermined temperature; a step of cooling the compound up to room temperature and precipitating a powder; a step of forming binary compound nano particles by repeating a process of dispersing the powder and performing a centrifugation twice or more times; and a step of vacuum-drying the binary compound nano particles.
