Photoelectric conversion element

Abstract

A photoelectric conversion element includes a photoelectric conversion layer, an anti-reflection film, a light scattering layer, and a transparent thin layer. The anti-reflection film is provided on a light-receiving surface side of the photoelectric conversion layer. The light scattering layer is made of a plurality of metal nano-particles that are two-dimensionally arranged to be opposite to the light-receiving surface of the photoelectric conversion layer. The transparent thin layer is provided between the photoelectric conversion layer and the light scattering layer. A thickness dlow of the transparent thin layer is represented by the following equation. 0 < d low < λ 0  ( n low n abs ) 2  1 n abs 2 - n low 2 [ Equation   1 ] wherein λ0 represents an arbitrary wavelength of light in vacuum, the light being able to be absorbed by the photoelectric conversion layer; nabs represents a refractive index of the photoelectric conversion layer at the wavelength; and nlow represents a refractive index of the transparent thin layer at the wavelength.
