Photoelectric conversion device.

摘要

The photoelectric conversion device comprises a plurality of electric conversion cells. Each cell is capable of performing a store operation, a read operation and a refresh operation. In the store operation, a potential of a control electrode region (base 4) of a semiconductor transistor is controlled using a capacitor (7) and carriers which have been generated by light excitation are stored in the control electrode region. In the read operation, a signal dependent on the voltage generated by the stored carriers is read out of a main electrode area (emitter 8) of the transistor. In the refresh operation, cariers stored in the control electrode region (4) are removed. A semiconductor region (emitter 8 min ) of the same conductivity type as of the main electrode region (emitter 8), is formed in the control electrode region (4) separately from the main electrode region (8).
