Zusammenfassung:An infrared photodiode includes a first electrode including a reflective layer, a second electrode facing the first electrode, and a photoelectric conversion layer between the first electrode and the second electrode. The photoelectric conversion layer includes an infrared absorbing material. A maximum absorption wavelength of the infrared absorbing material in a solution state is greater than about 700 nm and less than or equal to about 950 nm. The infrared photodiode is configured to exhibit an external quantum efficiency (EQE) spectrum in a wavelength region of greater than or equal to about 1000 nm.
