PRECURSOR FOR MANUFACTURING LIGHT ABSORBING LAYER OF SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a precursor for manufacturing a light absorption layer of a solar cell and a method for manufacturing the same. The precursor for the manufacturing the light absorption layer comprises: (a) a condensation composite; (b) a nano-particle of a core-shell structure; or (C) a mixture of the same. The condensation composite includes: a first phase composed of Cu-Sn bimetallic metal, and a second phase composed of chalcogenide having Zn; or the first phase composed of the Cu-Sn bimetallic metal, the second phase composed of the chalcogenide having the Zn, and a third phase composed of chalcogenide having Cu. The nano-particle of a core-shell structure includes a core; and a shell. The core is composed of Cu-Sn bimetallic metal nano-particles. The shell is composed of the chalcogenide having the Zn; or the chalcogenide having the Zn and the chalcogenide having the Cu.
