Actively cooling solar energy light gather generating set

Abstract

The invention discloses an actively cooling solar energy light gather generating set comprising a plurality of solar energy light gather generating die sets and a sun chasing tracker mounting system provided with the solar energy light gather generating die sets, wherein each solar energy light gather generating die set comprises a plurality of solar energy light gather generating units which are arranged in the form of matrix; the solar energy light gather generating unit comprises a condensing lens and a concentrator cell arranged in the condensing zone of the condensing lens; a semiconductor refrigeration sheet is arranged below the concentrator cell; the cold surface of the semiconductor refrigeration sheet is tightly stuck to the concentrator cell; and the concentrator cells are connected in series to externally output electric energy. In the light gather generating set of the invention, the semiconductor refrigeration sheet is arranged below the concentrator cell, the heat of the concentrator cell is transferred to a hot surface by the heat transfer action of the semiconductor refrigeration sheet to strengthen the heat dissipation effect of the concentrator cell so as to improve the photo-electricity conversion efficiency of the solar cell.

Description

technical field [0001] The invention relates to the field of concentrated solar power generation, in particular to a solar concentrated power generation device capable of actively dissipating heat from concentrator cells. Background technique [0002] Such as figure 1 As shown, in the existing solar concentrating power generation device, the concentrating power generation device often includes a concentrating lens. 2. Concentrating cells3. The condensed light of the secondary condensing prism 2 is projected onto the condensing cell 3 , so that the condensing cell 3 generates photoelectric conversion to generate electricity. However, when the secondary concentrating prism 2 is used to condense light again, the surface of the concentrating cell 3 will generate a very high temperature, which is generally 200 degrees, which is not conducive to the photoelectric conversion of the concentrating cell 3 and thus affects the efficiency of photoelectric conversion. A heat sink 4 is...
