Title:
SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2019/176646
Kind Code:
A1
Abstract:
A solar cell module (100) includes, in order from the light-receiving surface side, the following: a surface protective substrate (20) made of a resin; a gel-like polymer layer (22); a first sealing material layer (26); a photoelectric conversion unit; a second sealing material layer (28); and a backside protective layer (32) provided with a low heat expansion component aligned in one direction. The tensile elastic modulus of the gel-like polymer layer (22) is smaller than the tensile elastic modulus of any of the surface protective substrate (20), the first sealing material layer (26), and the second sealing material layer (28). The heat expansion coefficient of the backside protective layer (32) in one direction is smaller than the heat expansion coefficient of the surface protective substrate (20). The backside protective layer (32) is configured such that the heat expansion coefficient in the one direction and the heat expansion coefficient in another direction which is perpendicular to the one direction are mutually different.
