A semi conductor is irradiated with light such that carriers are uniformly generated throughout its volume. The semiconductor is n-type with ND = 1019/cm3. If the excess electron concentration in the steady state is ∆n = 1015/cm3 and if τp = 10µsec. (minority carrier life time) the generation rate due to irradiation
