We reported the crystal structure on surface of CZTS films using Raman spectroscopy by two-dimensional scanning. In addition, we analyzed the change in crystal structure before and after sulfur-anneal treatment to CZTS films. The result showed that Cu2S distributed on the surface of as-deposited CZTS films was estimated to be 13.0 (um)2 by high-resolution Raman mapping approaching the diffraction limit. Furthermore, it was found from the Raman mapping that the Cu2S phase was reduced by annealing sulfur at 600 ℃.
