Abstract
A sensor may include a reflective electrode, a photoelectric conversion layer on the reflective electrode and including one or more photoelectric conversion materials, a semi-transmissive electrode on the photoelectric conversion layer, a light transmitting buffer layer on the semi-transmissive electrode, and a semi-transmissive auxiliary layer on the light transmitting buffer layer.
