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

Figure 21

Cyclic voltammograms of ERY-sensitized RDS NiO spray-deposited onto ITO. All voltammograms have been under irradiation with white light (light source: halogen lamp; : 28.6 W cm⁻²). Scan rates have been varied between 25 and 55 mV s⁻¹. ERY-sensitized RDS NiO sample was initially cycled 60 times at 5 mV s⁻¹ in dark conditions (see Figure 18(a)). Counter electrode: Li; reference redox couple: Li⁺/Li. Electrolyte composition as in Figure 1. Arrows indicate the verse of potential scan.
