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 of CuO could replace pt electrodes well and can even give better efficiency under the optimization process. The intake of this compound in any of the two forms of copper oxide is toxic. If inhaled, Copper (I) oxide can cause damage to the respiratory tract, breathing complications, and cough. If ingested, it can give rise to irritation of the gastrointestinal tract, stomach pain, diarrhea, and vomiting. Copper (II) oxide also has the same symptoms if ingested, in addition to skin discoloration and vision problems. Both composites can give rise to "metal fume fever," a state that causes flu-like symptoms and is a risk that exists in the heating of copper or wire structures.
To conclude, Copper is reddish, soft, pliable, and malleable. It is the industrial metal with the best conductive capacity for electricity. When combined with oxygen, it forms copper oxide (I) or copper oxide (II). Both compounds have varied industrial applications. Copper oxide nanoparticles are currently of great importance due to their various applications, such as antimicrobial (eliminates bacteria and fungi), photocatalyst (degrades dyes), and components of electrical systems (magnetic stores and gas sensors).
