Title:
STACKED PHOTOELECTRIC CONVERSION ELEMENT, STACKED PHOTOELECTRIC CONVERSION ELEMENT ARRAY, NON-CONTACT TEMPERATURE MEASURING DEVICE, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/228733
Kind Code:
A1
Abstract:
This stacked photoelectric conversion element comprises a first photoelectric conversion element and a second photoelectric conversion element. The first photoelectric conversion element and the second photoelectric conversion element are stacked in the stated order from a light incidence side. The first photoelectric conversion element has a sensitivity characteristic in which a sensitivity peak exists at a wavelength λ1a. The second photoelectric conversion element has a sensitivity characteristic in which a sensitivity peak exists at a wavelength λ2a, and the relationship λ1a<λ2a is satisfied in the stacked photoelectric conversion element. The sensitivity of the second photoelectric conversion element at the wavelength λ2a is less than the sensitivity of the first photoelectric conversion element at the wavelength λ1a.
