Title:
METHOD FOR THE AQUEOUS LOW-TEMPERATURE PREPARATION OF CI(G)S NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2011/028011
Kind Code:
A2
Abstract:
The present invention relates to a method for preparing nanoparticles of CI(G)S(CuInxGa1-xSe2 0<x≤1), which serves as a light-absorbing substance for a compound thin film solar cell, by means of an aqueous reaction under low-temperature conditions. More particularly, the present invention relates to a method for the aqueous low-temperature preparation of CI(G)S nanoparticles, comprising: enabling at least copper compounds and carboxylic acid derivatives or polyelectrolytes to react under an aqueous solvent condition to produce complexes; and injecting one or more heteroelement compounds, selected from indium compounds and selenium compounds, into the solution obtained in the previous step, in order to produce CI(G)S nanoparticles under low-temperature conditions.
