シールする方式が一般的である。In recent demonstration experiments to increase the size of photovoltaic power generation systems, the size of solar cell modules has also progressed further.
In order to prevent the solar cell module from being destroyed due to the difference in thermal expansion coefficient between the transparent member 1 and the frame 6, the frame 6 is constructed to be somewhat larger than the panel in which the solar cells are integrated on one side of the transparent member 1. A common method is to seal the gap between the panel and the frame with a sealing material.

If a special jig is not used, misalignment may occur during the curing period, resulting in an uneven seal at the mating area between the panel and frame, and in particularly severe cases, an incomplete seal. There were drawbacks. As a result, water vapor enters into the panel through incomplete seals, corroding the metal of the internal leads 6 and the electrodes of the solar cell elements 3, resulting in disadvantages such as disconnection of the internal leads 6 and peeling of the metal of the electrodes. was there. Furthermore, PVB (
When polyvinyl butyral) is used, the intrusion of water vapor from incomplete parts of the seal has an adverse effect on the transparent filler itself, causing devitrification of the transparent filler and the transparent filler 4 and the transparent member 1. Phenomena such as peeling occur at the interface with the back surface material 2 may occur, resulting in fatal damage to the solar cell module.

傷も防止することが可能となった。FIG. 2 shows the structure of the solar cell Modineal according to the present invention. In the figure, 8 is a transparent member, 9 is a backing material, 1° is a solar cell element, 11 is a transparent filler, 12 is an internal lead, 13 is a frame with a U-shaped cross section, 14 is a sealing material, 15, 16, 17
18 is a protrusion provided inside the recess of the frame, and 18 is a transparent member 8.
and the transparent filler 11, 19 is the end face of the transparent filler,
2o indicates the interface between the transparent filler 11 and the back material 9. Here, among the protrusions provided inside the recess of the frame 13,
15 and 17 have the role of regulating the vertical movement of the panel, and the protrusions 16 have the role of regulating the panel's movement in the horizontal direction. Therefore, the panel has a protrusion of 16,1
6, 17, the sealing material present in the recesses 22, 23 and 24 within the recess into the frame 13 will ensure a complete seal. Also, the protrusion 160 lower end 2
1 is located above the interface 18 between the transparent member 8 and the transparent filler 11, so the interface 18 between the transparent member 8 and the transparent filler 11.
End face of transparent filler 19. The interface 2o between the transparent filler 11 and the backing material 9 can be made with special consideration during the sealing process using a special jig during the curing period of the sealing material. Frame 13
Since the filler 14 is sufficiently present in the recess 22 provided in the recess, the seal is complete, and no water vapor enters into the solar cell module through the incomplete part of the seal.
It is now possible to eliminate defects in the solar cell module caused by breakage of the internal lead 12 due to corrosion, peeling of the metal part of the solar cell element 1° due to corrosion, and the like. In addition, when PVB is used as the transparent filler 11, the imperfection of the seal causes water vapor to enter the solar cell, causing devitrification of the transparent filler 11 and the interface 18 between the transparent member 8 and the transparent filler 11. It is also possible to prevent fatal damage to the solar cell module due to peeling of the interface 20 between the transparent member 8 and the back material 9.

シール材として用いることが可能となった。Furthermore, when a solar cell module is actually installed outdoors, the temperature of the solar cell module reaches a maximum of about 60 to 70°C. In this case, if a thermoplastic sealing material is used, the sealing material will soften as the temperature of the solar cell module increases, causing the panel to shift downward, resulting in incomplete sealing between the panel and the frame 13. However, by using the frame according to the present invention, the displacement of the panel can be controlled by the protrusions 16, and the sealing performance can be perfected.Therefore, it has excellent weather resistance and is made of silicone,
It has become possible to use a thermoplastic butyl rubber sealant, which has a lower water vapor permeability and is also cheaper than polysulfide and urethane sealants, as a peripheral sealant for solar cell modules.

となった。According to the present invention, the reliability of the peripheral flexible portion of the solar cell module is greatly improved, and the airtightness of the seal portion is improved, eliminating the intrusion of water vapor into the inside of the solar cell module through the seal portion. There was no disconnection due to lead corrosion or peeling due to corrosion of the metal parts of the solar cell elements.
また透明充填材としてＰＶＢを用いた場合の失透。Also, devitrification occurs when PVB is used as a transparent filler.

向上した。The peeling phenomenon at the interface between the transparent filling material, the transparent member, and the backing material has also been eliminated, and the reliability of this type of solar cell module has also been greatly improved. In addition, it has become possible to use a thermoplastic butyl rubber sealing material that is inexpensive, has excellent weather resistance, and has a low water vapor permeability, which further improves reliability.
