An investigation of the effects of bulk and interface degradation processes
on the junction ideality factor is presented. The ideality factor is extra
cted from a description of the simulated current-voltage characteristics of
the junction, using a double exponential model. The junction ideality fact
or appears as a sensitive parameter appropriate to characterize the effect
of recombination losses and to quantify the magnitude of junction devices d
