Preparation of high Ga content Cu(In,Ga)Se2 thin films by sequential evaporation process added In2S3
High Ga content Cu(In,Ga)Se2 thin films incorporated sulfur were prepared by sequential evaporation from CuGaSe2 and CulnSe2 ternary compounds and subsequently Ga2Se3,ln2Se3 and In2S3 binary compounds.The In2S3/(Ga2Se3+ In2Se3) ratio was varied from 0 to 0.13,and the properties of the thin films were investigated.XRD studies demonstrated that the prepared thin films had a chalcopyrite Cu(In,Ga)Se2 structure.The S/(Se+S) mole ratio in the thin films was within the range from 0 to 0.04.The band gaps of Cu(In,Ga)Se2 thin films increased from 1.30 eV to 1.59 eV with increasing the In2S3/(Ga2Se3+ In2Se3) ratio.
