Abstract

The invention relates to a mixed multispectral photosensitive pixel group, a photosensitive device and a photosensitive system. The mixed multispectral photosensitive pixel group comprises at least one photosensitive pixel of chemical coating and at least one photosensitive pixel of semiconductor. In the invention, the photosensitive pixel of chemical coating is combined with the photosensitive pixel of semiconductor to generate the mixed multispectral photosensitive pixel so that a plurality of color signals and other spectrum signals can be simultaneously obtained, incident photon energy can be maximally used and an upper bound of a photoelectric conversion efficiency theory can be or almost be reached. Images of other spectrums, such as an ultraviolet image, a near infrared image and a far-infrared image, can be acquired and simultaneously colors can be completely reconstructed.

Description
