Abstrakt: A fast and facile ambient pressure solution chemical process was applied to grow chalcopyrite CuInSe2nanoparticles by using common and inexpensive polylol ethylene glycol(EG), diethylene glycol(DEG) and triethylene glycol(TEG) as solvent, copper(II) chloride, indium(III) chloride and selenium powder as precursors, hydrazine hydrate and ethylenediamine as reducing agent and polyvinylpyrrolidone as capping agent. The products synthesized were characterized by XRD, TEM, HRTEM, EDS and UV-vis measurements based on different solvents EG, DEG and TEG, refluxing temperature and time as well as PVP adding amounts. The well-dispersed and single-phase CuInSe2nanoparticles synthesized with TEG solvent were used to prepare nanoparticles colloidal ink by ultrasonically dispersing in absolute alcohol solvent and then deposit CuInSe2thin films by layer-by-layer dip-coating nanoparticles ink. The deposited thin films were annealed in Ar atmosphere at 550°C for 30 min. Photovoltaic test devices with Mo-coated glass/CuInSe2/CdS/i-ZnO/AZO configuration were fabricated using the ink-coated and annealed CuInSe2light-absorbing thin films, and the corresponding I-V characteristics were evaluated.
