Abstract
It is shown theoretically that the effective rate of carrier photogeneration in a longitudinal photoresistor, which directly initiates the conversion of the radiation into the electric current, can be positive, zero, or negative and significantly exceed the true carrier photogeneration rate in absolute value. The effects are shown to be caused by the photoinduced local space charge.
