Abstract
A photoelectric conversion apparatus of this invention has a high sensitivity and low noise, and can be formed to have a large area at a relatively low temperature since it has a light absorption layer (310), formed of a non-monocrystalline material, for absorbing light and generating photocarriers, and a multiplication layer (301, 303, 305, 307, 309) for multiplying the photocarriers generated by the light absorption layer.
