Electrochemical Characterization of Nanoporous Nickel Oxide Thin Films Spray-Deposited onto Indium-Doped Tin Oxide for Solar Conversion Scopes
Electrochemical impedance spectra of ERY-sensitized RDS NiO in dark conditions and irradiated with white light (source: halogen lamp with W cm−2). Spectra have been displayed as Nyquist plots. NiO film thickness: 0.3 μm; substrate: ITO. ERY-sensitized RDS NiO sample was polarized at 3.0 V versus Li+/Li during the recording of both spectra. Arrows indicate the direction of increase for the frequency of polarization.
