Abstract

See full text

In order to realize a light absorber wherein the wavelengths absorbed can be adjusted, an embodiment of the present invention provides a light absorber 100 provided with a group of dielectric protrusions 102, a conductive thin film 104, and a conductive thick film 108. The group of dielectric protrusions has each dielectric protrusion protruding at a random position on a dielectric surface. A dielectric thin film is disposed on or above at least part of the surface of the dielectric protrusions and on or above at least part of the dielectric surface where the dielectric protrusions are not present; and the dielectric thick film spreads out along the dielectric surface and being kept separate from the dielectric thin film. The group of dielectric protrusions can be provided by disposition of dielectric particles in an in-plane random arrangement on the surface. The present invention also provides a bolometer, an infrared light absorber, a solar thermal power generating device, and a radiative cooling film adopting the light absorber above as well as a method for manufacturing the light absorber.
