Figure 3From: Efficient p-type dye-sensitized solar cells with all-nano-electrodes: NiCo2S4 mesoporous nanosheet counter electrodes directly converted from NiCo2O4 photocathodesCV curves and Nyquist plots. (a) CV curves for the NiCo2S4 nanosheet and Pt-based counter electrodes. (b) Nyquist plots of EIS for symmetric cells assembled with two identical counter electrodes at an open-circuit voltage bias under dark condition.Back to article page
