Document Type and Number:
WIPO Patent Application WO/2021/106872
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a solar cell module having excellent workability during production, a production method for the same, and a building external wall material using the same. A production method for a solar cell module (10) in which a cover glass, a first sealing material containing a first resin, a design material containing a fluororesin, a second sealing material containing a second resin, and a solar cell are placed in the stated order, and then heated and compressed, said method obtaining a solar cell module (10) having, in the stated order from the light-receiving surface side of the solar cell module (10), a cover glass (11), a first sealing layer (12) formed from the first sealing material and having a thickness of 50 to 2,000 μm, a design layer (13) formed from the design material and having a thickness of 10 to 1,000 μm, a second sealing layer (14) formed from the second sealing material and having a thickness of 50 to 2,000 μm, and a solar cell (15), wherein the value obtained by subtracting Tm1 from Tmf and the value obtained by subtracting Tm2 from Tmf are both 30°C or higher, where Tmf [°C] is the melting point of the fluororesin, Tm1 [°C] is the melting point of the first resin, and Tm2 [°C] is the melting point of the second resin.
