| Abstract: | We studied the full‐energy peak efficiency of a Si drift detector (SDD) and a Si(Li) detector (SLD) using the formalisms proposed by Seltzer [Nucl. Instrum. Meth. 188 (1981) 133] and O'Meara and Campbell [X‐Ray Spectrom. 33 (2004) 146]. The respective adjustable parameters were fitted to full‐energy peak efficiencies measured with certified point radioactive sources. Seltzer's model was able to reproduce the experimental data for the SDD and the SLD in the 6–40 keV and 6–100 keV energy ranges, respectively. In turn, O'Meara and Campbell's formula also performed well for the SDD between 6 and 40 keV and proved to fit satisfactorily in the energy interval 6–60 keV for the SLD.
