PURPOSE:To prevent the solar cell efficiency from lowering by protecting the solar cell against overheat even when the solar beam impinges upon the light receiving face of the solar cell. CONSTITUTION:The outer wall 5 is made of a translucent material and opposed to the light receiving face of a solar cell 6. Spaces provided, respectively, between the solar cell 6 and the inner and outer walls 4, 5 constitute ventilation layers 7, 7 which serve as air paths 8, 8 for passing the air from a suction port 9 to a discharge port 10 in order to ventilate the solar cell 6 and the periphery. |
