Definitions

  • the present invention relates to an apparatus and a method for cooling solar cells by means of a flowing cooling medium, wherein the cooling medium is in direct or indirect thermal contact with at least one solar cell Ie and an external cooling device, as for example from DE 20 2007 002 087 Ul is known.
  • the efficiency of solar or photovoltaic cells in particular of silicon (Si) based solar cells, depends inter alia on the temperature. With increasing temperatures, the efficiency of crystalline Si solar cells decreases by about 0.4 percent per degree Celsius, and in the case of amorphous Si solar cells, the efficiency decreases by about 0.1 percent per degree Celsius. In direct sunlight, the temperature of a solar cell rises significantly above the ambient temperature, z. B. to over 35 degrees Celsius. This results in crystalline Si solar cells a calculated loss of efficiency of about 14 percent and in amorphous Si solar cells, a loss of efficiency of about 3.5 percent.
  • z For example, from 5 to 7 percent for large-scale produced amorphous Si solar cells and 16 to 20 percent for large-scale produced crystalline Si solar cells, it quickly becomes clear that the operating temperature of a solar cell represents a significant factor in terms of their yield. A reduction of the temperature can lead to a considerable increase in the performance of the solar cells with the same light irradiation. In general, a reduction of the temperature is achieved by an installation of the solar cells, in which an air flow is enabled or enforced and a corresponding solar cell module is cooled by air. Alternatively, active Cooling circuits, z. B. by a water cooling, be provided.
