The gas layer 11 may be made of N ₂ or CO ₂ gas. Further, the solar cell 9 may be brought into contact with the inner surface of the other outer shell material 5 without providing the gas layer 11. Further, the solar cell 9 is not adhered to any of the outer shell materials 4 and 5 but is simply accommodated in the space 6 and placed on the inner surface (upper surface) of the other outer shell material 5. But you can.

  The photovoltaic power generation panel 1 includes an output electric wire 12 extending from the electrode of the solar cell 9. An input terminal member 15 of an input electric wire which is an external electric device 14 is coupled to the output terminal member 13 which is an extending end portion of the output electric wire 12 by soldering.

  The outer shell materials 4 and 5 are made of a transparent plate made of glass or plastic. The spacer 7 is a resin square pipe extending long along the outer edge of each of the outer shell materials 4 and 5. A desiccant 18 is filled in the longitudinal direction of the spacer 7. A communication hole 19 for communicating the inside of the spacer 7 with the space 6 is formed. Through the communication hole 19, the space 6 is dried by the desiccant 18, and the humidity is always kept low.

  Inside the end portion 21 in the longitudinal direction of the spacer 7, the output terminal member 13 of the output electric wire 12 is entirely accommodated together with the input terminal member 15 coupled to the output terminal member 13. A cutout 22 is formed in the end 21 for opening the inside of the end 21 of the spacer 7 toward the outside of the photovoltaic power generation panel 1. Further, a cover body 23 that closes the notch 22 so as to be opened and closed is provided, and the cover body 23 is formed integrally with the end portion 21. In addition, you may provide the said cover body 23 separately from the said spacer 7 as shown with a dashed-dotted line in FIGS. 1-5.
