Chalcopyrite, CuInxGa1-xSe (CIGS), is widely applied in the fabrication of thin-film solar cells, due to its high efficiency and stability. The high costs and complexity of vacuum processes have driven the development of non-vacuum methods, such as solvothermal approaches using organic solvents and metal salts. To overcome the problems of energy waste and carbon residue, this study synthesized ink of CIGS nanoparticles using the solvent-thermal refluxing method at 250 C with polyetheramine as the chelating solvent. The resulting CIGS particles were characterized by XRD, Raman, TEM and UV-vis to investigate the crystal structure, composition, morphology, and band gap. This paper demonstrates the considerable potential for the synthesis of nanoscale CIGS particle ink using a low-cost, simple process, applicable for mass production.
