Abstract
A structure of an artificial electronic retina is disclosed, which includes an array of a plurality of photoelectric units, and each photoelectric unit includes one electronic photosensitive element, one microelectrode, one electronic circuit, and sidewalls surrounding the photoelectric unit, wherein the microelectrode is disposed on and electrically connected to the electronic photosensitive element, and the electronic circuit is disposed on the electronic photosensitive element adjacent to the sidewalls near the circumference of the electronic photosensitive element. A layer of a light-permeable conductive material is disposed on the electronic photosensitive element between the microelectrode and the electronic circuit, wherein the layer of the light-permeable conductive material is electrically connected to both the electronic photosensitive element and the microelectrode. Therefore, the input and output power of the electronic photosensitive element can be increased without reducing the photosensitive area of the electronic photosensitive element.
