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

Figure 22

Comparison of the cyclic voltammograms of ERY-sensitized CS NiO coating (thickness: 0.3 μm) in the dark and under illumination with the white light produced by a halogen lamp ( = 28.6 W cm⁻²). The applied potential was scanned at the rate of 5 mV s⁻¹. Electrolyte composition as in Figure 1. Arrows indicate the direction of potential scan. Profiles have been extracted from Figure 19 (dark conditions) and Figure 20 (illuminated state).
