Summary: 
Polycrystalline Cu(In,Ga)Se2 (CIGS) films were prepared by heat treatment of metallic precursors using dimethylselenium (Se(CH3)2), which is a less hazardous Se source than H2Se gas. CIGS films were fabricated at various Se(CH3)2 supply rates. We investigated the effect of the Se(CH3)2 supply rate on the crystal phase and surface morphology of the films.
