SYNTHESIS OF I-III-VI2 NANOPARTICLES AND FABRICATION OF POLYCRYSTALLINE ABSORBER LAYERS

摘要

A method for preparing III-VI2 nanoparticles and a thin film of polycrystalline light absorber layers. The method for preparing I-III-VI2 nanoparticles comprises the steps of: (a1) preparing a mixed solution by mixing each element from groups I, III and VI in the periodic table with a solvent; (a2) sonicating the mixed solution; (a3) separating the solvent from the sonicated mixed solution; and (a4) drying the product resulted from the above step (a3) to obtain nanoparticles.
