A permanent lifetime recovery can be achieved through a regeneration treatment under illumination at elevated temperature. To evaluate the applicability of BO mitigation by means of regeneration at industrial relevant conditions, industrially-made PERC solar cell precursors were processed in a coupled fast firing and regeneration tool where the latter comprises an illuminated zone through which the solar cells transit on a belt. The treatment was evaluated by a subsequent intentional degradation. The results show that untreated solar cells suffer from BO-LID while properly treated samples are almost free of BO-LID demonstrating the applicability of a fast (around 15–30 s) and coupled regeneration process in mass production. Furthermore, it is found that fluctuations in precursor quality and/or variations in firing conditions are of minor significance for the BO-LID mitigation process. The firing conditions process window (peak firing temperature and belt velocity) overlaps with the treatment conditions window having the benefit of independent optimization.</dcterms:abstract> <dcterms:title>Industrially applicable mitigation of BO-LID in Cz-Si PERC-type solar cells within a coupled fast firing and halogen lamp based belt-line regenerator : A parameter study</dcterms:title> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Herguth, Axel</dc:contributor> <dc:creator>Pernau, Thomas</dc:creator> <dc:rights>terms-of-use</dc:rights> </rdf:Description> </rdf:RDF>
