Band Tunable Microcavity Perovskite Artificial Human Photoreceptors

Electronic device versions of the neural functions of the human retina have high potential for use in artificial vision. This study demonstrates halide perovskite artificial human photoreceptors with specific photoresponses to red, green, and blue colors, which are consistent with human retinal photoreceiving cones and rods. In contrast to the current programmable spectral-response technologies, a novel microcavity structure is combined in this...
