Cu(In,Ga) (S,Se) 2 thin films were fabricated by sequential evaporation from CuGaSe 2 , CuInSe 2 and In 2 S 3 compounds for photovoltaic device applications. From XRF analysis, the Cu:(In + Ga):(S + Se) atomic ratio in all thin films was approximately 1:1:2. As the [In 2 S 3 ]/([CuGaSe 2 ] + [CuInSe 2 ]) mole ratio in the evaporating materials increased, the S/(S + Se) atomic ratio in the thin films increased from 0 to 0.16 determined by XRF and to 0.43 by EPMA. XRD studies demonstrated that the prepared thin films had a chalcopyrite Cu(In,Ga) (S,Se) 2 structure and the preferred orientation to the 112 plane. The SEM images demonstrated that Cu(In,Ga) (S,Se) 2 thin films had large and columnar grains. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
