Effect of the tunnel-current blocking by excess nonequilibrium quasi-particles is discussed, as an example, for the low-resistance tunnel junctions formed by normal metal and superconducting lead. As shown, the tunnel current suppression is determined by the ratio of a recombination time of quasi-particles to the tunnelling time and depends on the voltage applied to the junction.

Key words: nonequilibrium superconductivity, phonons, tunnel junction, superconductors, heterostructures.
