Abstract
A photodetector element has a photoelectric conversion layer containing aggregates of semiconductor quantum dots QD1 that contain a metal atom and containing a ligand L1 that is coordinated to the semiconductor quantum dot QD1, and a hole transport layer containing aggregates of semiconductor quantum dots QD2 that contains a metal atom and containing a ligand L2 that is coordinated to the semiconductor quantum dot QD2, the hole transport layer being arranged on the photoelectric conversion layer, where the ligand L2 includes a ligand represented by any one of Formulae (A) to (C).
