Presented at: 25th European Photovoltaic Solar Energy Conference and Exhibition - 5th World Conference on Photovoltaic Energy Conversion, Valencia, Spain, 6-10 september 2010.

This paper describes the progress of the research and development that is carried out by a consortium in the frame of the European project ROBUST DSC. The project spans a wide range of activities from basic research including innovative materials development, advanced characterization, and predictive modeling to more applied technology development including aspects like up scaling of fabrication technology and accelerated and outdoor lifetime testing of representative module prototypes. The combined efforts have led to maximum power conversion efficiencies under full sunlight of >12.0 % for single cells with active areas < 0.2 cm2 and total area module efficiencies between 4 and 5 % for aperture areas of up to 225 cm2. Accelerated life time testing at elevated temperatures and continuous illumination reveals dynamic ageing patterns with negligible degradation after 1000 hours of ageing for all investigated cell and module designs up to temperatures of 60 °C, storage up to 85 oC resulted in typically 5-20 % decrease of performance, depending on design and materials.
