Abstract

Various embodiments include apparatuses including optical and optoelectronic devices and methods of making same. One such device includes an image sensor having an integrated circuit with a number of pixel electrodes, a substantially-continuous optically-sensitive layer, and at least one counter-electrode. The substantially continuous optically sensitive layer is in electrical communication with both the number of pixel electrodes and also the counter-electrode. Additional apparatuses and methods are disclosed.
