摘要（英）：

The present invention discloses a photoelectric device, an image sensor and an electronic device. The photoelectric device includes a first photoelectric conversion layer including a heterojunction that includes a first p-type semiconductor and a first n-type semiconductor, a second photoelectric conversion layer on the first photoelectric conversion layer and including a heterojunction that includes a second p-type semiconductor and a second n-type semiconductor. A peak absorption wavelength ([lambda]max1) of the first photoelectric conversion layer and a peak absorption wavelength ([lambda]max2) of the second photoelectric conversion layer are included in a common wavelength spectrum of light that is one wavelength spectrum of light of a red wavelength spectrum of light, a green wavelength spectrum of light, a blue wavelength spectrum of light, a near infrared wavelength spectrum of light, or an ultraviolet wavelength spectrum of light, and a light-absorption full width at half maximum (FWHM) of the second photoelectric conversion layer is narrower than an FWHM of the first photoelectric conversion layer.
