Shockley-Read-Hall (SRH) recombination is the main determinant for the effective minority carrier lifetime in silicon. This research has focused on the study to find the recombination strength of interstitial iron on low injection Shockley-Read-Hall recombination in compensated solar grade silicon by means of analytical modelling. This study found that strength of iron in SRH recombination is depends on the doping concentration and symmetry of minority carrier capture cross-section. This study shows that iron become more recombination active at higher doping and at lower symmetry of capture cross-section.
