It shows the temperature 02 of the temperature equalization block 2 heated by the solar collector 1 and the temperature 03 of the temperature equalization block 4 cooled by the heat radiation fins 05. According to FIG. 5, as the temperature 02 of the temperature equalization block 2 on the high temperature side increases, the output 01 increases, but as the temperature difference between the temperature 03 of the temperature equalization block 4 on the low temperature side and the temperature 02 decreases. Almost no electricity will be generated. Therefore, power generation is performed only during the daytime when the temperature difference is large6.
[Problems to be Solved by the Invention] As described above, conventional thermoelectric conversion devices generate electricity only during the day when the temperature difference between the temperature equalization block on the high temperature side and the temperature equalization block on the low temperature side is large.
