CIGS nanoparticles were synthesized by a low temperature colloidal route for the absorber layer of photovoltaic devices. The CIGS nanoparticles were prepared by reacting CuI, InI 3 , GaI 3 in pyridine with Na 2 Se in methanol at 0°C under inert atmosphere. The reaction products of dark red and yellow colors were turned out to be NaI and CIGS nanoparticles, respectively, by ICP-AES and SEM-EDS analyses. Chalcopyrite structure of the CIGS nanoparticles was confirmed by XRD and TEM diffraction patterns. As compared to the particles from Cu 0.9 In 0.8 Ga 0.3 Se 2 ratio, more uniform and smaller nanoparticles were obtained from Cu 1.1 In 0.68 Ga 0.23 Se 1.91 stoichiometric ratio. The CIGS nanoparticles were measured to be in the ranges of 5-20 nm. However, tube like CIGS particles with length of several γn and width in the range of 100-300 nm were obtained from Cu 0.9 In 0.8 Ga 0.3 Se 2 , and Cu 0.9 In 0.7 Ga 0.4 Se 2 . The morphological change of the CIGS particles seems to be closely related to the ratio of Cu/(In+Ga). [ABSTRACT FROM AUTHOR]
