    • For recombination rates we find that ktr/kss, 4.4 for non-TiCl4 cells, and 5.5 to 6 for TiCl4 cells. However, neither the power law γ values from Figure 4 (γ, 1, 4.7-5.4) nor that derived from distributions of states in Figure 3 (γ, 1, 5.4) is changed by the TiCl4 treatment, which leads to some internal inconsistency. For transport, ktr/kss, 1.7 to 2.3, again far from the γ derived from distributions of states. Lagemaat et al. also found, for short circuit transport, ktr/kss, 2. The authors claimed this was consistent with the density of states distribution. However, these authors did not actually measure the density of states distribution directly. Instead it was calculated from the kinetic data, thus weakening the case for determination of y from the density of states, van de Lagemaat, J, Kopidakis. N, Neale, N. R, Frank, A. J. Phys. Rev. B 2
