Concentrating solar power generation device

The invention relates to a concentrating solar power generation device, which comprises a concentrating lens (1), a solar cell panel (3), a shell (2) and a heat concentrating and radiating device (4). The concentrating solar power generation device is characterized in that the solar cell panel is in the shape of a spherical surface or a flat plate; the concentrating lens is in the shape of a convex spherical surface; the shell is in the shape of an inverse hollow cone, and the upper bottom and the lower bottom of the shell are respectively consists of the spherical concentrating lens and the solar cell panel in a replacing way; and the heat concentrating and radiating device is made from an integrated hollow thin-wall material, is arranged at the midpoint of a sealed cavity, is internally provided with a water inlet pipe (5) and a water outlet pipe (6), and is used for radiating heat when flowing water and concentrating heat when not flowing water. By adopting the principle that the electric current of the PN
