Abstract:
A photoelectric conversion element includes a PN junction formed between an N-type oxide layer and a P-type oxide layer, in which the N-type oxide layer is formed of an oxide having a perovskite structure containing titanium and strontium, a part of strontium is substituted with a +3 valence metal element or a part of titanium is substituted with a +5 valence metal element, and the amount of the metal element substituted in the N-type oxide layer is 0.01 mass % to 0.75 mass %.
