Abstract
Cu2ZnSnS4 CZTS films were prepared by sulfurization of sputtered Zn/Sn/Cu multilayer thin films Raman peaks at 251 cm−1 289 cm−1 336 cm−1 and 362 cm−1 were detected and the optical band gap energy of the CZTS was estimated to be about 153 eV Energydispersive spectrometry and xray photoelectron spectroscopy reveal that the composition ratio of prepared CZTS film is close to stoichiometric Photoresponse current measurements show persistent photoconductivity effect with decay constants τ and β of 504 and 0269 respectively
