Abstract:

Nano-materials are considered as building blocks of many optoelectronic devices. They differ from bulk counterpart in the size, characteristic and their new physical properties and offer new opportunities to be employed in various applications. Zero dimensional (0D) and one Dimensional (1D) nanostructures have attracted lots of attention in solar energy harvesting, conversion and storage, owing to their unique physical and chemical properties. Zinc oxide (ZnO) nano-wires provide separation and transportation of the generated carriers by the excitation of the attached Quantum Dots (QDs). The geometry of the NWs arrays allows improved optical reflection and light trapping leading to enhancing the light absorption. Furthermore, ZnO NWs will drive and direct the transportation of the photo-generated electrons, and thus improving the energy conversion efficiency of the solar cell. In this presentation, we will discuss one dimensional nanostructure in quantum dots sensitized solar cells and the role they play in increasing the conversion efficiency of solar cells, taking in consideration the materials to be used to meet the main objective of developing an eco-green solar cell with high conversion efficiency.
