摘要： A sensor includes an anode and a cathode, and a near-infrared photoelectric conversion layer between the anode and the cathode. The near-infrared photoelectric conversion layer is configured to absorb light of at least a portion of a near-infrared wavelength spectrum and convert the absorbed light into an electrical signal. The near-infrared photoelectric conversion layer includes a first material having a maximum absorption wavelength in the near-infrared wavelength spectrum and a second material forming a pn junction with the first material and having a wider energy bandgap than an energy bandgap of the first material. The first material is included in the near-infrared photoelectric conversion layer in a smaller amount than the second material.

摘要： 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.
