Abstract We propose and demonstrate to derive the Auger recombination coefficient by fitting efficiency–current and carrier lifetime–current curves simultaneously, which can minimize the uncertainty of fitting results. The obtained Auger recombination coefficient is $1.0\times10^{-31}$ cm$^{6}$s$^{-1}$ in the present sample, which contributes slightly to efficiency droop effect.
