An investigation was made of the photoconductivity of a-Si:H at 125 degree K. The experimental results were used as the basis of a model according to which the recombination and nonequilibrium carriers is due to the tunnel effect and the photoconductivity is associated with the hopping motion of photocarriers between localized states in the absence of a quasiequilibrium. The absence of photoconductivity due to the motion of delocalized carriers is attributed to the asymmetry of the band tails.
