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 1.0×10~(-31) cm~6 s~(-1) in the present sample, which contributes slightly to efficiency droop effect.
