Abstract. Chalcopyrite copper-indium-gallium-diselenide (CIGS) nanoparticles are useful for photovoltaic applications. In this study, the synthesis of CIGS powder was examined, and the powder was successfully synthesized using a relatively simple and convenient elemental solvothermal route. From the reactions of elemental Cu, In, Se and Ga(NO3)3 powders in an autoclave with ethylenediamine as a solvent, spherical CIGS nanoparticles, with diameters ranging from 20-40 nm, were obtained using a temperature of 200°C for 36h. The structure, morphology, chemical composition and optical properties of the as-synthesized CIGS were characterized using X-ray diffraction, transmission electron microscopy, selected area electron diffraction, scanning electron microscopy, inductively coupled plasma-mass spectrometry. In this sample, the mole ratio of Cu:In:Ga:Se was equal to 0.89:0.71:0.29:2.01, and the optical band gap was found to be 1.18 eV. The solar cell obtained a power conversion efficiency of 5.62% under standard air mass 1.5 global illumination.

“…Irregular shaped particles with a wide size distribution have been obtained. CIGS nanoparticles with 15-70 nm diameter could be obtained by reacting under nitrogen atmosphere a mixture of CuI, InI 3 , and GaI 3 in pyridine with Na 2 Se in methanol at 0°C using mechanical stirring min (Chun et al 2005;Ahn et al 2007). The size of these nanoparticles are tunable from 15 to 70 nm when the reaction time is increased from 1 to 5 min (Chun et al 2005;Ahn et al 2007).…”

“…Various synthesis approaches have been recently developed specifically to produce sub-micron CIGS particles (Gurin 1998;Azad-Malik et al 1999;Czekelius et al 1999;Grisaru et al 2003;Castro et al 2004;Chun et al 2005;Roh et al 2005;Wei and Mu 2005;Dutta and Sharma 2006;Nakamura et al 2006). There are very few cases where monodispersed chalcopyrite nanoparticles with a diameter around 5 nm or less are obtained.…”

A new green synthesis method of CuInS₂ and CuInSe₂ nanoparticles and their integration into thin filmsAbstract A new preparation method for CuInS 2 and CuInSe 2 nanoparticles synthesis is described without using any organic solvent. Heating Cu, In, and S/Se precursors dissolved in water for 30 min in a microwave oven in the presence of mercapto-acetic acid leads to monodispersed chalcopyrite nanoparticles. No precipitation of these nanoparticles is observed after several months at room temperature. These new materials have been thoroughly characterized to confirm their compositions, sizes, and structure without any filtration. Transmission electron microscopy (TEM) confirmed particle sizes below 5 nm. Energy dispersive X-ray analysis (EDXA) confirmed the chemical composition of these samples. X-ray diffraction (XRD) showed a chalcopyritetype structure with crystallite size of about 2 nm.

“…In the last few decades, the solvothermal method also emerged as a powerful tool for the synthesis of nanostructures/microstructures, using organic amine as a solvent. Luo et al [4], Jiang et al [5], Li et al [6], and Chun et al [7] have reported that the CIS can be synthesized by solvothermal route, although its longer reaction time (15-36 h) and difficulty in controlling the morphology of the particles limit the synthesis of high-quality CIS nanoparticles. Recently, synthesis of nanoparticles based on microwave heating is found to be a good technique because of its various advantages, such as shorter reaction time, low level of impurities, high crystallinity, excellent reproducibility, and high yield of product.…”

Highly crystalline CIS nanoink was synthesized using highly efficient microwave route. Thin films of CIS were fabricated using the developed ink by drop casting method. XRD pattern of CIS thin films indicates that a chalcopyrite phase with good crystallinity can be obtained using developed ink and that the composition of precursor ink can be transferred directly to the thin film without change in the stoichiometry. The developed ink alleviates the need of organic binders/dispersant and high temperature selenization using highly toxic H 2 Se gas (or Na 2 Se as a Se source) after deposition of thin film absorber layer. UV-VIS-NIR absorption analysis indicates that CIS thin film has a band gap of around 1.18 eV.
