ABSTRACT:
A semiconductor cell for generating current in response to incident radiation, particularly solar energy, wherein a layer of material having charges is disposed over the PN current generating junction. The layer having charges possesses a net bound charge of the same polarity as the minority carriers associated with the underlying semiconductor material for aiding minority carrier flow across the PN junction and for minimizing recombination of those minority carriers at the surface of the semiconductor body.
