Abstract
A photoelectric conversion element includes a photoelectric conversion layer to include a first metal layer, a semiconductor layer, and a second metal layer, all of which are laminated. In addition, at least one of the first metal layer and the second metal layer is a nano-mesh metal having a plurality of through holes or a dot metal having a plurality of metal dots arranged separately from each other on the semiconductor layer. The photoelectric conversion layer includes a long-wavelength absorption layer containing an impurity which is different from impurities for p-type doping and n-type doping of the semiconductor layer. The long-wavelength absorption layer is within a depth of 5 nm from the nano-mesh metal or the dot metal.
