FACESS, Flexible autonomous cost efficient energy source and storage: Final report

Kari Rönkä (Editor)

    Research output: Book/ReportReport


    The key objective of Flexible Autonomous Cost Efficient Energy Source and Storage, FACESS project was to develop roll-to-roll printing process for organic solar cells (OSC) devices and thin film batteries (TFB). A control transistor circuitry on foil, which controls the operation voltage and charge of TFB's was also to be developed. The integration of OSC and TFB modules and control transistor circuitry into a flexible autonomous energy source and storage device was also one of the key objectives of the project. No material development was performed in the project, and thus only commercial materials were used. The technical target specification for OSC module was: 2.5% @ AM1.5, A~100 cm2, 250 mW and for the TFB module: Li-ion, 1-3 mAh/cm2, A~30 cm2. The FACESS project (FP7 - 2007-ICT-1-215271) funded by European Commission was executed between January 1st 2008 and April 31st 2011. The developments were carried out by the following consortium: VTT Technical Research Centre of Finland (coordinator), IMEC Interuniversity Micro-Electronics Centre (Belgium), CEA Commissariat à l'Energie Atomique (France) ,WUT Warsaw Technical University (Poland), Umicore S.A.(Belgium), Coatema Coating Machinery GmbH (Germany), Suntrica Oy (Finland) and Coatema Machinenbau GmbH (Germany). In this final report the key achievements, problems faced, lessons learned, as well as the vision and exploitation towards the large-scale production of flexible OSCs and TFBs, have been presented.
