Fabrication and characterization of nanostructured fluorine doped tin oxide thin film for dssc by hydrothermal method

Nanostructured Fluorine Doped Tin Oxide (FTO) thin film has been successfully synthesized on top of bare FTO layer substrates using hydrothermal method. The performance of FTO thin film including conductivity and transparency depend on the surface morphology and the properties of the material. Hy...
