Nonequilibrium quasiparticle-energy distributions in weakly illuminated aluminum--aluminum-oxide--lead-bismuth tunnel junctions are obtained from current-voltage characteristics. A highly accurate method of unfolding I(V) to deduce f(E) is presented which is applicable for asymmetric-tunnel-junction analysis. Illumination from either side of the tunnel junction was performed, with differing resulting tunneling behavior. The unfolded results in both cases are in good agreement with a T* description of the nonequilibrium quasiparticle distribution on the aluminum side.
