PURPOSE:To achieve effective recovery of solar energy by a method wherein a part of a outer pipe is formed as a condensing lens, also at least a part of inner pipe is formed in a plane shape on which solar battery is fixed, in the titled device where a space between a inner pipe and a outer pipe is formed as being under vacuum condition. CONSTITUTION:An inner pipe 2 is composed concentrically with a outer pipe 1 having light permeability, and connected to the outer pipe 1 with bellows 4, the space between the pipe 1 and the pipe 2 is kept under adequate vacuum condition as required for heat insulation. The middle part of the inner pipe 2 is formed as semi-circular cylinder 6 on which single crystal silicon solar battery 7 formed in square shape is fixed with bonding agent having excellent thermal conductivity, for instance, a silver paste or a soldering material. A part of the outer pipe 1 opposing to the side where the solar battery 7 is attached, is formed as a condensing lens 8. Thereby, recovery of solar energy can be achieved effectively in the form of both heat and electricity. |
