Abstract :
External photoluminescence (PL) quantum efficiencies of more than 6% at room temperature and of more than 10% at lower temperature from crystalline silicon wafers are presented. The radiative recombination probability under optimum injection conditions is shown to exceed 20% at room temperature, which demonstrates that radiative recombination can be one of the dominant recombination channels in high quality silicon.
