PURPOSE:To remarkably improve a solar cell panel in photoelectric conversion efficiency by a method wherein solar rays are incident on a panel, and the solar rays reflected from the panel concerned are made to be incident on another panel again in succession. CONSTITUTION:Solar ray A1 incident straight on a cylindrical body 10 of an equilateral hexagon through an incident opening 10c of the cylindrical body 10 primarily hits a solar cell panel 11b located at the base, a part of light reflected by the panel 11b is incident again on a solar cell panel 11a arranged on the side wall through a reflection corner. Solar ray A2 obliquely incident on the cylindrical body 10 hits the solar cell panel 11a on the side wall and light reflected from it is made incident again on an opposed other panel 11a successively. As mentioned above, in a cylindrical body provided with many solar cell panels inside it, the panels mutually reflect solar rays, so that the reflected solar rays are effectively absorbed by the panels as incident solar rays and the loss caused by the scatter of the reflected light rays is almost eliminated, and consequently a solar cell device of this design can be sharply improved in photoelectric conversion efficiency. |
