Consider silicon at a temperature of 300 [K], and a donor concentration ND = 4·1015 [cm-3]. The thermal equilibrium recombination rate is RP0=1·1011 [cm-3 s-1 ]. A uniform generation rate by illumination produces an excess-carrier concentration of on δn= δp=1·1014 [cm-3 ]. Note that at a temperature of 300 [K], the commonly accepted value for the intrinsic carrier concentration of silicon is ni = 1.5·1010 [cm-3] A) By what factor does the total recombination rate RP increase under illumination with respect to thermal equilibrium, RP/RP0 ?
