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. WebJan 1, 2024 · Crystalline silicon (c-Si) is the dominating photovoltaic technology today, with a global market share of about 90%. Therefore, it is crucial for further improving the performance of c-Si...
