Patent Searching and Data

A manufacturing method of a compound semiconductor nanoparticle for solar cells
Document Type and Number:
Japanese Patent JP6281835
Kind Code:
PROBLEM TO BE SOLVED: To provide a method for easily producing at low cost sulfide nanoparticles of a metal material which forms a light absorption layer of a solar cell.SOLUTION: In a method for producing metal sulfide nanoparticles, a metal complex in which xanthate is coordinated is heated under an inert atmosphere. The metal xanthate has a molecular structure in which a metal ion is coordinated with the xanthate. The nanoparticles being a metal sulfide are produced by heating this metal xanthate. For this reason, a light absorption layer can be easily formed in a non-vacuum process at low temperature.
