Abstract:
This work reports on the results obtained in the EU project FoXy (contract nr SES6-019811). FoXy has been carried out in the 6th Framework Program in the Sustainable Energy Systems. It consists of a Europe-wide consortium of small and medium size enterprises, research institutes and universities. The project has aimed at developing cleaning and crystallisation processes for metallurgical SoG-Si feedstock, optimize associated cell and module processes, and set parameters for these types of feedstock. The major goals of the project have been: (i) achieve a significant cost reduction through more efficient cleaning processes for raw materials, (ii) secure high volume production of SoG-Si, (iii) develop recycling techniques for end-of-life products, (iv) shorten the energy payback time significantly, (v) manufacture wafers on a large-scale industrial production line 150x150mm2 aiming at 16-17% cell efficiency with increased yield. This work summarizes the highlight results of this three-year project.
