A condition of applicability of the Boltzmann equation for calculating the relaxation time of holes in isotropic polycrystalline p-type silicon is formulated for hole scattering both by a disordered system of potential barriers on the surfaces of crystallites and a disordered lattice of silicon atoms characterized by a local order. An assessment of the range of applicability of the Boltzmann equation for calculating the relaxation time of holes in isotropic polycrystalline p-silicon is made for a given scattering mechanism in the temperature T = 200–600 K and hole concentration p = (5.0 - 10.0)·1019 cm-3 ranges. The mean distance Lφ covered by a charge carrier, when it loses the phase due to inelastic phonon scattering, is estimated for an isotropic polycrystalline p-silicon.
