<p><P>PROBLEM TO BE SOLVED: To provide a concentrating solar collector and an array of the same, and to reduce the maintenance cost. <P>SOLUTION: The concentrating solar collector 200 is composed, by using a transparent and solid optical element 210, provided with a convex surface 212 relatively large on its back, a concave surface 217 in a center of a front surface which is small and possesses an optical axis X jointly with the convex surface 212, and an aperture surface 215 around the concave 217, which has a flat surface having no metal film and which is substantially orthogonal to the optical axis X. A primary mirror 230 is formed on the surface of the convex surface 212, a secondary mirror 240 is formed on a surface of the concave 217 as a metallic-reflecting films, and a photovoltaic cell 220 is disposed in a center and flat part 213 of the surface of the convex surface 212. The primary mirror 230 is divided into a metal film 231 and 234 through a gap 237, and these are connected to each other at the photovoltaic cell 220. In case of manufacturing an array, a plurality of the collectors 200 are assembled on an optical panel in a honeycomb structure, and adjacent metal films are connected or integrated with each other among collectors 200. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
