CuO nanomaterials could also be used as good substitution for expensive noble metal cathode in dye solar cell
CuO nanomaterials could also be a good substitution for expensive noble metal cathodes in dye solar cells. This topic was first introduced by Anandan et al. In 2005, the optimal power conversion efficiency when using CuO nanorods as electrodes was 0.29% compared with 1.23% when using Pt as an electrode in the same condition, using CuO nanoneedles of the higher surface active area, Liu et al. They obtained an efficiency of 1.12% for TiO2-based dye solar cells. This result shows that nanomaterials
