Fig. 20From: Photoelectrochemical properties of mesoporous NiO x deposited on technical FTO via nanopowder sintering in conventional and plasma atmospheresEffect of light on the Nyquist plots of ERY sensitized RDS NiO x polarized at 2.9 V vs Li+/Li. High (upper plot), and low (lower plot) frequency range. Arrows indicate the verse of growing frequencies for the different profiles. White light intensity: 25 W cm−2 Back to article page
