From Lab to Fab: Bifacial n-Type Cells Entering Industrial Production

31st European Photovoltaic Solar Energy Conference and Exhibition; 965-968
Challenges and advancements of manufacturing the BiSoN cell concept of ISC Konstanz in the industrial production line of MegaCell srl are reported. As for processing BiSoN cells only standard equipment is needed, a fast transfer of processes from laboratory to production was possible, allowing for starting series production with median efficiencies above 19% after only some test runs. In a phase of debugging and process optimization several drawbacks limiting cell efficiency could be identified and extinguished. Especially for the wet processes the transfer from lab to fab required adaptations. After three months of operation a median production efficiency of 19.8% was reached, with identified potential for further improvements.
