Title:
PHOTOELECTRIC CONVERSION ELEMENT, IMAGING DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/127603
Kind Code:
A1
Abstract:
Provided are a photoelectric conversion element, an imaging device, and an electronic apparatus capable of achieving higher response speed. A first photoelectric conversion element (10) of an embodiment of the present disclosure is provided with: a first electrode (11); a second electrode (16) disposed opposite the first electrode (11); an organic layer (13) provided between the first electrode (11) and the second electrode (16) and including a hole transport material; a work function adjustment layer (15) provided between the second electrode (16) and the organic layer (13) and having an electron affinity or a work function greater than a work function of the first electrode (11); and an electron block layer (14) provided between the organic layer (13) and the work function adjustment layer (15), and having an anisotropic electric susceptibility of more than or equal to 413 or an intramolecular dipole moment of more than or equal to 1.84 debye.
