In order to shorten the period in which the cost required for manufacturing a solar cell module can be recovered as a power generation output and to reduce the cost of a power generation system using a solar cell, solar light is collected by using a condensing lens. In recent years, research has focused on concentrating solar cells that can increase the amount of incident light into a cell and reduce the use area of expensive solar cells. However, the solar cell using the silicon device has a property that the amount of power generation is significantly reduced when the temperature rises.

Therefore, the conventional light concentrating solar cell apparatus has a problem that the temperature rise of the solar cell is remarkable as well as the light condensation increases, and thus it is difficult to perform sufficient cooling. Therefore, in order to cool the solar cell more efficiently and effectively, In order to suppress the decrease in the amount of power generated by cooling the cooling system, a technique for improving its durability has been studied.
