Abstract: Provided is a photosensitive material and a photodetector including the same. According to the present invention, the photodetector may include a photoactive layer having a photocurrent density of at most about 10−6 A/cm2 under a first incidence condition, and having a photocurrent density of at least about 10−4 A/cm2 under a second incidence condition. The wavelength of light under the second incidence condition is the same as the wavelength of light under the first incidence condition, and the intensity of light under the second incidence condition may be greater than the intensity of light under the first incidence condition.
