Method of cooling solar cells

摘要

A solar cell is disposed on the lower wall of a pipe and a plate-shaped optically transparent piece formed of a material which transmits light covers a window provided at a position in the upper wall of the pipe opposite to the solar cell so as to provide a method of efficiently and effectively cooling the cell. Sunlight is made to converge by a converging lens on a light receiving surface of the solar cell via the optically transparent piece. Coolant flows through the pipe, the light receiving surface of the solar cell is directly cooled by this coolant, and the heat of the sunlight converged by the converging lens is thereby removed by the coolant.
