This work reports on the synthesis of nanopowder and nanoink of Copper-Indium-Gallium-(di)Selenide (CIGS) (CuIn0.7Ga0.3Se2) of 20-80 nm with a band gap of 1.1 eV by a facile microwave technique. For CIGS synthesis, precursor mixtures consisting of metal acetylacetonates and selenium powder in oleylamine were heated in a microwave at 180-210 degrees C for 20-60 min. The resultant nanopowder was characterized and optimized for particle size by dynamic light scattering, phase by X-ray diffraction, morphology, and elemental distribution by scanning electron microscopy and band-gap by UV-Vis-near-infrared spectroscopy. CIGS ink, suitable for spin coating and ink-jet printing, was prepared and thin film was deposited and characterized.
