3 FAQs about [Solar cell impurities]

How do impurities affect the bulk minority carrier lifetime?

Impurities distributed throughout the bulk primari- ly impact the bulk minority carrier lifetime through the generation of recom- bination centers, thereby reducing the photogenerated carrier density and increasing the reverse saturation current of the solar cell p-n junction.
