Gettering in silicon photovoltaics: a review

WebFirst, we review key silicon sources for n-type solar cells and present various recharging technologies. We then present the impact of impurities on silicon solar cells with a focus on metallic impurities, oxide precipitates, and thermal donors. We then present strategies to mitigate the impact of metallic impurities via gettering.
