FEATURES OF SILVER THIN FILMS APPLIED ON FTO GLASS PLATE FOR DYE-SENSITIZED SOLAR CELLS USING GREEN SYNTHESIS AND CATHARANTHUS ROSEUS LEAF EXTRACT

Silver thin films accumulated on an FTO-coated glass substrate with different molar concentrations using the spray pyrolysis process. Silver-nanostructured films are deposited using Catharanthus roseus leaf extract and silver nitrate solution. According to the study, growth and shape/size are significantly influenced by the silver thin film method's response time. Silver thin films have been studied using the UV-visible spectrophotometer, Photoluminescence [PL], Field Emission Scanning Electron Microscope (FE-SEM) with EDX, X-Ray Diffraction (XRD), and finally AFM techniques. Lastly, these films are effectively applied in dye-sensitized solar cells.
