Silicon photovoltaic cells are preferred in today,s market conditions and technological implementations because are cheap, abundant and the ongoing research has made them more and more efficient. In spite of that, manufacturing of such solar cells is very energy consuming, and silicon cells are very gragile and prone to breaking in the most mildly hostile situations. Hence, there is a lot of potential in the manufacture and use of flexible solar cells. Possible uses for this solar cell technology could be printing on glass, plastics, flexible cloth materials, and theoretically anything you could imagine. This will give endless opportunities for car makers to implement solar cells on their cars, an small gadgets would never have their battery depleted while it is sunny outside. The aim of this Project is to develop a complete CdTe based thin film flexible as well as based on glass substrates solar cells using nanostrutured surfaces as the key point for reaching in a first step the levels of efficiency of standard commercial Si on glass based solar cells. The research and future production in Europe of ghis innovative approach would give an extraordinary input to build a solid background for the EU industry to further increase the industrial production of CdTe based thin film solar cells devices. Nanostructured surfaces will be utilized as one of the key tecnologies for improving the cell efficiency with the goal to reach the same efficiencies as for today,s standard commercial silicon based solar cells. This objetive will be completed in three segments stages: the preparation of materials, the complete characterization of the materials, and the characterization of the final solar cells. To prepare the needed pn-junctions, standard processes as closed space sublimation and chemical bath deposition will be used. Further, the nanostructured surfaces will be prepared by modern approaches such as low energy ion and/or laser sputtering. Finally, the electroding will be made using approaches based on transparent conductive oxides (TCOs such as ZnO: Al, ITO, etc). Simulation tools sill be required at each step in order to et the optimal geometry and dimensions of the solar cell. In the materials characterization phase, a complete set o classical and modern techniques will be used to characterize ino order to give feedback to the preparation process for improving their efficiency. The expected outcomes will be innovative nanostructured solar cells which will have n extraordinary benefit in the expected efficiency, and with a possibility of commercialization as a final step.
