Abstract
Quaternary Cu
2 MnSnS 4 ( thin films were synthesized via three different chemical methods. The as obtained CMTS
thin films were characterized by X Ray diffraction, scanning electron microscopy and UV vis NIR absorbance spectroscopy
measurements. The CMTS thin films exhibit the polycrystalline nature of the CMTS films with stannite structure. From the
scanning electron microscopy images, CMTS thin films are found to have different morphologies. The optical band gap
values are estimated to be 1.15, 1.26 and 1.17eV, respectively. All CMTS thin films show p-type semiconductor material
characteristic. The results indicate that the as obtained CMTS thin films are a potential candidate for application as absorber
layer in thin film solar cells..
