摘要

We present n-type Czochralski-grown silicon solar cells made from 100% upgraded metallurgical grade silicon feedstock, with an independently certified peak efficiency of 21.1%. We look at the impact of net doping and minority carrier lifetime and mobility on the short-circuit current and the open-circuit voltage.
