Abstract

In this article, single-phase CuIn(SxSe1-x)2 thin films with different x have been prepared using a new two-step method consisting of partly selenizing Cu–In precursors in Se ambient, and then exposing the partly selenized films to H2S/Ar under different conditions. The x-ray diffraction indicated that the CuIn(SxSe1-x)2 films exhibited the homogeneous chalcopyrite structure. With the increase of the sulfurization temperature from 425 to 525 °C, x increases from 0 to 1, Eg increases from 0.95 to 1.42 eV, the Raman shift of the A1[Se–Se] mode increases from 173 to 197 cm−1, and the resistivity increases from 101 to 103 Ω.cm.
