COPPER-ZINC-TIN-SULFUR-SELENIUM-BASED NANO-PARTICLE PRECURSOR, A METHOD FOR MANUFACTURING THE SAME, THE COPPER-ZINC-TIN-SULFUR-SELENIUM-BASED NANO-PARTICLES USING THE SAME, AND A METHOD FOR MANUFACTURING THE NANO-PARTICLES CAPABLE OF ECONOMICALLY OBTAINING HIGH EFFICIENT SOLAR CELLS

摘要

PURPOSE: A copper-zinc-tin-sulfur-selenium(CZTSS)-based nano-particle precursor, a method for manufacturing the same, the CZTSS-based nano-particles using the same, and a method for manufacturing the nano-particles are provided to synthesize the CZTSS-based nano-particle precursor by hardly using toxic materials.;CONSTITUTION: A CZTSS-based nano-particle precursor is synthesized by irradiating microwave to a reacting solution containing copper, zinc, tin, and sulfur. The composition ratio of the copper, the zinc, the tin, the sulfur is adjusted according to the pH value of the reacting solution. The microwave irradiation is implemented for 5 minutes to 1 hours under 100-700W. A method for manufacturing the CZTSS-based nano-particle precursor includes the following: the reacting solution is prepared; the pH value of the reacting solution is adjusted; the microwave is irradiated to the reacting solution. The CZTSS nano-particle precursor is separated.;COPYRIGHT KIPO 2012
