Abstract
A photoelectric conversion device includes a first photoelectric conversion portion configured to generate electrons; a second photoelectric conversion portion configured to generate holes; a charge-to-voltage conversion portion including an n-type first semiconductor region configured to collect the generated electrons and a p-type second semiconductor region configured to collect the generated holes, the charge-to-voltage conversion portion being configured to convert a charge that is based on the electrons and the holes to a voltage; and a signal generation portion configured to generate a signal corresponding to the voltage, the signal generation portion including an amplification transistor.
