Nebulizer spray pyrolysis technique has been employed to deposit the CuInGaS2 (CIGS) counter electrode at different substrate temperatures. The XRD patterns revealed that the obtained films are in tetragonal structure with the preferential orientation of (112) plane and crystalline parameters were calculated. The A1 mode of CIGS film was observed at 296cm−1 by Raman spectra, which is a combination...
