Abstract

Analytical expressions for the average concentrations of photogenerated electrons and holes are obtained outside the framework of the quasineutrality approximation in the case of a strong surface recombination in the presence of a single-level impurity recombination centers. It is shown that the quasineutrality approximation becomes incorrect with decreasing sample size in the direction of irradiation.
