METHOD FOR MANUFACTURING BIMETALLIC OR INTERMETALLIC PRECURSOR FOR MANUFACTURING CIGS LIGHT ABSORBING COMPOUND OF SOLAR CELL

摘要

The present invention relates to a method for manufacturing a bimetallic or intermetallic precursor for manufacturing a CIGS light absorbing compound of a solar cell. The method for manufacturing a bimetallic or intermetallic precursor includes a process (a) of preparing a metal salt solution by dissolving at least two kinds of metal salt selected from a group consisting of Cu salt, In salt, and Ga salt in a solvent; a process (b) of preparing a reductant solution by dissolving a reductant in a solvent; and a process (c) of supplying the metal salt solution to the reductant solution by a spray method.
