摘要

We present here our latest results of boron and phosphorus diffusion gettering of iron in crystalline silicon. The gettering efficiency is evaluated measuring both the minority carrier lifetime as well as the solar cell parameters. The results indicate that the optimal dopant and time-temperature profiles strongly depend on the thermal history as well as the initial iron level present in silicon.
