ABSTRACT:
By maintaining the first electrodes of a photogenerative element and a current blocking element at a common potential while electrically interconnecting the second electrodes thereof, the blocking element need not be masked from incident radiation because the stored electrical signal generated by the photogenerative element will not be dissipated by photogenerated carrier pairs contributed by the current blocking element.
