Abstract

CuInS₂ colloidal nanocrystals were synthesized via a facile solution-processed method, using a CuIn(OH)₅ precursor. The Cu-In metal hydroxide precursor was prepared by co-precipitation in aqueous solution: an aqueous NaOH solution was reacted with a metal cation solution containing Cu²⁺ and In³⁺ ions at room temperature. Oleic acid was added as a surfactant and bis(trimethyldisilyl)sulfide was injected to provide a sulfur source for the formation of CuInS₂ nanocrystals. The CuInS₂ colloidal nanocrystals had mixed crystal structures of zincblende and wurtzite, confirmed by XRD and TEM. The CuInS₂ nanoparticles were of average size 5.6 nm and had a 1:1:2 chemical composition. Paste of the as-prepared CuInS₂ nanocrystals were coated as a thin film absorber layer for photovoltaic cells by doctor blading, yielding cell efficiency of 1.26%.
