1. An image sensor, comprising:
a substrate;
a plurality of pixels disposed on the substrate and including a blue pixel, a green pixel, and a red pixel, at least a portion of the plurality of pixels comprising:
a first photo-sensing device including:
a first electrode and a second electrode,
a first photoelectric conversion layer between the first electrode and the second electrode, the first photoelectric conversion layer including a material including a first perovskite which absorbs at least a portion of light in a visible light wavelength spectrum, and
a charge auxiliary layer disposed at least one of between the first electrode and the first photoelectric conversion layer and between the second electrode and the first photoelectric conversion layer; and
a second photo-sensing device which is stacked with the first photo-sensing device and senses at least a portion of light in an infrared wavelength spectrum.
