15. Equation requires the assumption of charge neutrality, i.e., the electron and hole charge densities are equal. The term (1+λ) arises due to the power dependence of n in dndt. An alternative formulism for Eq. can be found from considering the shape of the density of states [J. Bisquert and V. S. Vikhrenko, J. Phys. Chem. B JPCBFK 1089-5647 108, 2313 (2004)].
