<p><P>PROBLEM TO BE SOLVED: To improve a photoelectric conversion efficiency of a photoelectric conversion element by enhancing light absorptivity. <P>SOLUTION: The photoelectric conversion element 10 includes a photoelectric conversion layer 20, an antireflective film 32 provided on the side of a light receiving surface of the photoelectric conversion layer 20, a plurality of metal nanoparticles 36 arrayed in two dimensions on the opposite side of the light receiving surface of the photoelectric conversion layer 20, and a dielectric layer 38 covering surfaces of the metal nanoparticles 36. A number density of the plurality of metal nanoparticles 36 ranges from 5.0×10<SP POS="POST">8</SP>particles/cm<SP POS="POST">2</SP>or greater to 3.0×10<SP POS="POST">9</SP>particles/cm<SP POS="POST">2</SP>or less. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
