Cu3BiS3 is an absorber material for thin film solar cells with an optimal band gap of 1.10-1.72 eV, high absorption coefficient (>105 cm-1) and abundant constituents. In this paper, the effect of annealing on the properties of chemical bath deposited (CBD) Cu3BiS3 thin films is reported. The annealed Cu3BiS3 thin films were characterized by using the X-ray diffraction (XRD) and Raman spectroscopy. The XRD analysis revealed the formation of polycrystalline Cu3BiS3 thin films with orthorhombic crystal structure at 673K. The average crystallite size as calculated from the Debye-Scherrer’s formula was found to be 22.09 nm for (131) peak. Raman spectra showed a leading peak at 282 cm-1 that is a characteristic of Cu3BiS3.
