LIGHT CONDENSING DEVICE, PHOTOVOLTAIC POWER GENERATOR, AND METHOD FOR MANUFACTURING LIGHT CONDENSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light condensing device excellent in light condensing efficiency, a photovoltaic power generator provided with the light condensing device, and a method for manufacturing the light condensing device.SOLUTION: In a first optical member, a plurality of light condensing structures condensing a luminous flux incident on a first surface are arrayed on the first surface in a parallel manner with each other; a plurality of deflection structures deflecting each of the condensed luminous flux condensed by the plurality of light condensing structures are arrayed on a first rear surface in a parallel manner with each other corresponding to the plurality of light condensing structures; and each of the plurality of deflection structures emit the condensed luminous flux deflected by a deflection surface from an emission surface. In a second optical member, a plurality of light receiving structures receiving the condensed luminous flux emitted from the emission surface are provided protrusively on a second surface in a parallel manner with each other corresponding to the plurality of deflection structures; the condensed luminous flux received by each of the plurality of light receiving structures is reflected by a second rear surface; a main body portion of the second optical member is formed of a glass member; and each of the plurality of light receiving structures are formed of a resin material and are joined to the main body portion.
