Abstract
A combination sensor may include a first infrared light sensor and a second infrared light sensor. The first infrared light sensor may be configured to sense light in a first wavelength within an infrared wavelength spectrum. The second infrared light sensor may be configured to sense light in a second wavelength that is different from the first wavelength within the infrared wavelength spectrum. The first infrared light sensor and the second infrared light sensor may be stacked in relation to each other.
Claims20
A combination sensor, comprising:
- a first infrared light sensor configured to sense light associated with a first wavelength within an infrared wavelength spectrum;
- and
- a second infrared light sensor configured to sense light associated with a second wavelength within the infrared wavelength spectrum, the second infrared light sensor being stacked to the first infrared light sensor,
- wherein the second infrared light sensor includes
- a first electrode and a second electrode facing each other, and
- a first photoelectric conversion layer between the first electrode and the second electrode, the first photoelectric conversion layer including a first light absorbing material configured to selectively absorb infrared light including the second wavelength.
