Herein, F-doped Cu2O thin films with different F content are first synthesized on the ITO glass via a simple electrochemical deposition method. The prepared F-doped Cu2O thin films present n-type semiconductor character and show significantly high electronic and optical properties, especially for the one with preparation molar ratio of F/Cu = 1:2. This sample owns a unique net microstructure for a best absorption of visible-light and its electron concentration is more than ten times as that of pure Cu2O. Additionally, it has a lowest resistivity, which is beneficial for photogenerated charge t...
