Effect of sensitization on the electrochemical properties of nanostructured NiO
Screen-printed NiO electrodes were sensitized with 11 different dyes and the respective
electrochemical properties were analyzed in a three-electrode cell with the techniques of cyclic
voltammetry and electrochemical impedance spectroscopy. The dye sensitizers of NiO were organic
molecules of different types (e.g., squaraines, coumarins, and derivatives of triphenyl-amines and
erythrosine B), which were previously employed as sensitizers of the same oxide in dye-sensitized
