    Abstract: A photoelectric diode includes a first electrode and a second electrode facing each other; a photoelectric conversion layer between the first electrode and the second electrode, and a compensation layer on the photoelectric conversion layer, the compensation layer being configured to compensate absorption and reflection of light. The photoelectric conversion layer is associated with a first optical spectrum having a light-absorption peak at a first wavelength and a reflection peak at a second wavelength, the first wavelength and the second wavelength both within a wavelength region of about 750 nm to about 1200 nm. The photoelectric diode is associated with a second optical spectrum having a light-absorption peak at a third wavelength, the third wavelength is within the wavelength region of about 750 nm to about 1200 nm, the third wavelength different from the first wavelength.

    Abstract: A sensor includes first and second electrodes, and an infrared photoelectric conversion layer between the first and second electrodes, the infrared photoelectric conversion layer being configured to absorb light in at least a portion of an infrared wavelength spectrum and convert the absorbed light to an electrical signal. The infrared photoelectric conversion layer includes a first material having a maximum absorption wavelength in an infrared wavelength spectrum, a second material forming a pn junction with the first material, and a third material having an energy band gap greater than the energy band gap of the first material by greater than or equal to about 1.0 eV. The first material, the second material, and the third material are different from each other, and each of the first material, the second material, and the third material is a non-polymeric material.

    Abstract: A sensor includes a first electrode, a second electrode facing the first electrode, and a light absorbing layer between the first electrode and the second electrode. The light absorbing layer may have a first absorption spectrum having a first absorption peak in a first infrared wavelength region and a second absorption peak in a second infrared wavelength region, the second infrared wavelength region being a longer wavelength region than the first infrared wavelength region. The second absorption spectrum does not at least partially overlap with the first absorption spectrum. The second absorption spectrum may have a lower absorption intensity than the first absorption spectrum. An external quantum efficiency (EQE) spectrum that is amplified in the second infrared wavelength region is exhibited in the sensor.
