PHOTOELECTRIC CONVERSION ELEMENT

摘要

A photoelectric conversion element 10 includes a photoelectric conversion layer 20, an anti-reflection film 32, a light scattering layer 36, and a transparent thin layer 50. The anti-reflection film 32 is provided on a light-receiving surface side of the photoelectric conversion layer 20. The light scattering layer 36 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 20. The transparent thin layer 50 is provided between the photoelectric conversion layer 20 and the light scattering layer 36. A thickness d low of the transparent thin layer 50 is represented by the following equation. 0 < d low < » 0 �¢ n low n abs 2 �¢ 1 n abs 2 - n low 2
wherein » 0 represents an arbitrary wavelength of light in vacuum, the light being able to be absorbed by the photoelectric conversion layer 20; n abs represents a refractive index of the photoelectric conversion layer 20 at the wavelength; and n low represents a refractive index of the transparent thin layer 50 at the wavelength.
