Abstract
An organic photoelectric conversion element, an imaging device, and an optical sensor, which can detect a plurality of wavelength regions by a single element structure, are provided. The photoelectric conversion element is formed by providing an organic photoelectric conversion portion including two or more types of organic semiconductor materials having different spectral sensitivities between the first and the second electrodes. Wavelength sensitivity characteristics of the photoelectric conversion element change according to a voltage (bias voltage) applied between the first and the second electrodes. The photoelectric conversion element is mounted in the imaging device and the optical sensor.
