Patent ID: 6936806

Claim:
A photoelectric conversion device having a layered structure, said layered structure comprising: a carrier generation/multiplication layer composed of amorphous silicon to have both the function of absorbing light and generating carriers through optical excitation and the function of multiplying the generated carriers; an electron injection inhibiting layer composed of an amorphous silicon carbide of p-type conductivity to inhibit injection of electrons into the carrier generation/multiplication layer; and a hole injection inhibiting layer composed of amorphous silicon nitride of n-type conductivity to inhibit injection of holes into the carrier generation/multiplication layer, wherein said carrier generation/multiplication layer is provided between said electron injection inhibiting layer and said hole injection inhibiting layer, and an energy level at an interface between said amorphous silicon nitride layer and said amorphous silicon layer is discontinued on a valance band side and equal on a conduction band side.
