Electrochemical Characterization of Nanoporous Nickel Oxide Thin Films Spray-Deposited onto Indium-Doped Tin Oxide for Solar Conversion Scopes

Figure 24

Scan rate () dependence of the cathodic current density peak () present in the voltammograms of ERY-sensitized CS NiO coating deposited on ITO. Data have been extracted in the dark (from Figure 19) and under illumination (from Figure 20). The potential corresponding to the cathodic current density peak varies between 3.1 and 3.2 V versus Li⁺/Li, depending on the scan rate.
