    Abstract: A sensor includes a first electrode, a second electrode facing the first electrode, and a light absorbing layer between the first electrode and the second electrode. The light absorbing layer may have a first absorption spectrum having a first absorption peak in a first infrared wavelength region and a second absorption peak in a second infrared wavelength region, the second infrared wavelength region being a longer wavelength region than the first infrared wavelength region. The second absorption spectrum does not at least partially overlap with the first absorption spectrum. The second absorption spectrum may have a lower absorption intensity than the first absorption spectrum. An external quantum efficiency (EQE) spectrum that is amplified in the second infrared wavelength region is exhibited in the sensor.

    Abstract: A solar cell includes an active layer between a first electrode and a second electrode, and a transport layer between the active layer and one of the first or second electrodes. A plurality of nanoparticles are included in at least one of the active layer or the transport layer. The nanoparticles may have the same or different shapes or sizes and may be spaced differently based on location. The nanoparticles may be made of metal or a different material and the active layer may be made from an organic photovoltaic material.
