PURPOSE:To utilize sunlight, which is inputted from the north, by bonding a panel, on which prism type converging devices are arranged, to the north side of a planer panel. CONSTITUTION:On a panel 23, ordinary planer panels 21 are arranged so as to face the south and prisim type converging devices 22 are arranged on a flat plate so as to face the north. The panel 23 is bonded with an upper side 24. These units are arranged in the direction of the north and the south. Each prism type converging device 22 is formed in a wedge shape with a transparent dielectric medium. A bottom surface 32 is made to be a mirror surface or an interface with air. An energy conversion element such as a solar cell and the like is bonded to a light receiving surface 33. Light 34, which is inputted through an aperture plane 31, is guided to the light receiving surface 33 by utilizing reflection by a mirror or a total reflection and the total reflection at the aperture plane 31. Therefore, it is effective that the prism type converging device is provided so as to face the north. Meanwhile, since the ordinary planar type panel is suitable for facing the south, the highly effective panel can be thus constituted when both parts are assembled. |
