The light-condensing mirror structure 400 is located at a side of the first double-sided light-energy utilization unit 100 facing away from the cover 500, and is configured to condense light from a side of the first double-sided light-energy utilization unit 100 to the second light-energy utilization portion 120 of the first double-sided light-energy utilization unit 100. And the light gathering mirror structure 400 is in thermal contact with the cover 500 for conducting heat from the cover 500 to the light gathering mirror structure 400.
Because the concentrating mirror structure 400 is in thermal contact with the cover 500, the heat of the cover 500 can be conducted to the mirror structure, and the larger heat dissipation area of the concentrating mirror structure 400 is effectively utilized to dissipate heat, which is beneficial to reducing the temperature of the light energy utilization device in the concentrating solar system, thereby being beneficial to improving the efficiency and the service life of the light energy utilization device. And has the advantages of higher reliability and less weight increase than the solution of heat dissipation by using the cooling liquid.

Specifically, referring to fig. 2, in one embodiment, the heat sink 300 has a sheet structure, one end of the heat sink 300 contacts the transparent body 200, and the other end contacts the light-condensing mirror structure 400.
Because the two ends of the heat dissipation member 300 are respectively contacted with the transparent body 200 and the light condensation mirror structure 400, the heat of the first double-sided light energy utilization unit 100 can be conducted to the light condensation mirror structure 400 through the heat dissipation member 300, so that the heat dissipation effect is improved by using the larger heat dissipation area and faster heat exchange rate of the light condensation mirror structure 400.
