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

Figure 18

(a) Modification of the voltammogram of ERY-sensitized RDS NiOx on ITO at 5 mV s−1 in dark conditions upon continuous cycling (nickel oxide sample as in Figure 7). Electrolyte and cell configuration as in Figure 1. After about 60 cycles the voltammogram had a stabilized profile. Arrows indicate the verse of potential scan. (b) Cyclic voltammograms of ERY-sensitized RDS NiO spray-deposited onto ITO after stabilization of the voltammogram (a). All voltammograms have been recorded in dark conditions. Scan rates have been varied between 5 and 55 mV s−1. ERY-sensitized RDS NiO sample was initially cycled 80 times at 5 mV s−1 (a). Counter electrode: Li; reference redox couple: Li+/Li. Electrolyte composition as in Figure 1. Arrows indicate the verse of potential scan.
