Abstract

A photoelectric conversion device includes: a fluorescent light guide plate that has a plate-shaped structure in which fluorescent substances that absorb sunlight and emit fluorescent light are dispersed and which is formed of a material having a refractive index different from a refractive index of an outside, the fluorescent light emitted from the fluorescent substances being concentrated onto an edge surface to be emitted when the sunlight is incident; a first photoelectric cell configured to generate power by being irradiated with the sunlight; a lens layer configured such that light incident from an outer surface is concentrated onto the first photoelectric cell; a second photoelectric cell configured to generate power by being irradiated with the fluorescent light emitted from the edge surface of the fluorescent light guide plate; and power output units configured to extract power obtained in the photoelectric cells.
