Abstract

Provided is an inverted photoelectric conversion element having high conversion efficiency. A photoelectric conversion element according to the present disclosure includes, in sequence, a first conductive layer having light transparency, a hole transport layer, a light-absorbing layer expressed by a composition formula AgBiI, an electron transport layer, and a second conductive layer. In the composition formula, the composition ratio a, b, and c satisfies c=a+3b and 2≤b/a≤4, and light incident through the first conductive layer is photoelectrically converted.
