In this paper, a formed water lens is formed of flat light transmission member 11b formed of glass or resin having a water channel confronting a plurality of light incident members 11a.Abstract:
PURPOSE:To inexpensively manufacture a solar generating device having high light collecting efficiency by forming a formed liquid lens. CONSTITUTION:A formed water lens 11 is formed of flat light transmission member 11b formed of glass or resin having a water channel 11c confronting a plurality of light incident members 11a. On the other hand, a plurality of solar cells 3 are placed on a solar cell support 14 so as to be disposed at the focuses of the water lenses. Thus, the similar light collecting efficiency to the optical convex lens can be carried out with the members 11a and water having approximately equal light refractive index to that of the members 11a, and can also be formed remarkably inexpensively. When the solar light rays 6 collected via the water lenses pass the water, a part of the heat ray energy of the solar light rays is absorbed to the water 16 to convert the energy, and accordingly the solar cells 3 can be protected against the high temperature damage.read more
