Abstract

For the purpose of improving the reproducibility and the semiconductor properties of chalcopyrite CuInS 2 thin film, potassium hydrogen phthalate (C 8H 5KO 4), as a complex agent, was added into the sulphate bath system. The optimum process parameter for the preparation of CuInS 2 thin film was determined by orthogonal experiment method. The effect of C 8H 5KO 4 on the composition and Mott-Schottky behavior of the as-deposited film was studied with electron dispersion spectroscopy (EDS) and alternating current (AC) measurement. It was found that the as-deposited film was p-type semiconductor with the flatband of 0.665 V and the acceptor density of 3.06×10 19 cm -3; the addition of C 8H 5KO 4 can effectively enhance the composition stability of the film and decrease its flatband potential and acceptor density.
