摘要: Abstract Cu2FeSnS4 (CFTS) thin film has been synthesized by rapid thermal annealing sulfurization of radio-frequency magnetron sputtered precursor. X-ray diffraction pattern indicates that all phases belong to CFTS with tetragonal structure. The strain which exists in the is calculated be 8.29×10−3 using Williamson–Hall method. Raman spectrum and infrared reflectivity present two A1, B three E optical vibration modes. band gap evaluated 1.42 eV transmission spectrum. electrical properties structure glass/Mo/CFTS/CdS/i-ZnO/AZO have also discussed. open circuit voltage (Voc) 110 mV, short density (Jsc) 2.5 mA cm−2 fill factor (FF) 26.3%. These results are helpful preparation further study films for solar cell application.
