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

Figure 12

Electrochemical impedance spectra of NiOx sintered via CS at different applied potentials (2.8 and 3.55 V versus Li+/Li) when film thickness is μm. In the larger picture 40 mHz marks the onset of the diffusive regime in when polarized at 2.8 V. In the inset the specified frequencies refer to the point of closure of the high-frequency semicircles. For cell configuration and electrolyte used, see Figure 1.
