Photoelectric converting apparatus to prevent the outflow of excess carriers

摘要

A photoelectric converting cell has a control electrode region of a semiconductor transistor (S1). The carriers generated in the control electrode region by the light excitation are accumulated, and the accumulation voltage generated by this accumulation is read out from one of the main electrode regions of the semiconductor transistor. The control electrode region is connected to an excess carrier eliminating circuit (D1, Lrh, Ve) to perform the switching operation in dependence on the potential difference across the control electrode region.
