- Abstract
- In this study, we have prepared the Cu(InGa)Se2 (CIGS) thin film absorber layers by evaporation of CIGS powders and solution spray deposition with different atomic ratio compositions. High quality and well faceted chalcopyrite thin films were obtained by these simple deposition processes. CIGS absorber thin films were grown with polycrystalline chalcopyrite structures with preferred orientation of (112) directions. Our results showed that CIGS powder evaporation and solution spray deposition processes are promising candidate for the solar cell grade CIGS thin film absorber layer depositions. © 2010 IEEE.
