A photoelectric and photothermal combined generating device for tracking concentrating solar energy comprises a light collecting slot (2) with a high reflecting inner surface, a sun tracking device with a high reflecting inner surface, a heat exchange pipe (5), a rotating shaft (7), a water outlet pipe (8) and a water inlet pipe (9), the rotating shaft (7), the water outlet pipe (8) and the water inlet pipe (9) being separately mounted at two ends of the heat exchange pipe (5); and is characterized by further comprising a plano-convex lens (1) mounted at the top of the light collecting slot (2) and a photocell panel (3) mounted at the focus below the plano-convex lens (1). The photocell panel (3) is fixed together with the heat exchange pipe (5) through an electrical insulating film (4), the light collecting slot (2) is V-shaped and adopts the structure that the bottom is open, and the light collecting slot (2) is positioned above the photocell panel (3) and fixed on the heat exchange pipe (5). By means of the present invention, the strength of the sunlight projected on the surface of the photocell panel is greatly enhanced, the output power of the photocell panel is increased, and the input cost of photoelectric equipment is reduced. The photothermal utilization and the photoelectric utilization are combined and carried out synchronously, the solar utilization ratio is increased significantly, and water in the heat exchange pipe can reach a high temperature through the converged sunlight in a short time. |
