The parameters of p-n-p structures based on polycrystalline cadmium telluride films exhibit non-monotonic variation with increasing doses of γ radiation. It is established that this behavior is related to an increase in the base thickness and to a nonmonotonic dose dependence of the minority carrier lifetime, which is accompanied by recharge of the surface states and a by a change in the potential barrier height at the grain boundaries.
