Description: Das Projekt "Ultra thin solar cells for module assembly -tough and efficient (ULTIMATE)" wird vom Umweltbundesamt gefördert und von Fraunhofer-Institut für Solare Energiesysteme durchgeführt. The overall objective of the current project is to make a significant contribution to the dissemination of PV in order to improve the sustainability of the European energy supply, to reduce environmental hazards such as global warming and to strengthen the economical situation of the European PV industry. The main project objective is the demonstration of PV modules using solar cells which are substantially thinner than today s common practice. We will reduce the current solar cell thickness from typically 200-250 mym down to 100 mym. Assuming a projected kerf loss of 120 mym for 2010, this will enable more than 50Prozent additional wafers to be cut from each silicon ingot. Additionally, by using advanced solar cell device structures and module interconnection technology, we target to increase the average efficiency for these thin cells up to 19Prozent for mono-crystalline and 17.2Prozent for multi-crystalline silicon and to reach a module-to-cell efficiency ratio above 90Prozent. The processing and handling of wafers and cells will be adapted in order to maintain standard processing yields. Including scaling aspects, this corresponds to a module cost reduction of approximately 30Prozent until 2011 and 1.0 /Wp extrapolated until 2016. Furthermore Si demand can be reduced from 10 to 6 g/Wp providing a significant effect on the eco-impact of PV power generation. The partners of this project form an outstanding consortium to reach the project goals, including two leading European R&D institutes as well as five companies with recorded and published expertise in the field of thin solar cells. The project is structured in 5 work packages covering the process chain from wafer to module as well as integral eco-assessment and management tasks. The expected impact of the project is a PV energy cost reduction of approximately 30Prozent, a significant reduction of greenhouse gas emissions and an improved competitiveness of the European solar cell, module and equipment manufacturers.
