Solar cell module

A solar cell module, comprising:

• a first protective layer comprising a resin and being light transmissive, the first protective layer having a first surface and a second surface opposite to the first surface;
• a second protective layer having a third surface facing the second surface, and a fourth surface opposite to the third surface;
• a solar cell portion including one or more solar cell elements between the second surface and the third surface;
• a first filler layer covering the one or more solar cell elements between the second surface and the solar cell portion, the first filler layer comprising a resin;
• a second filler layer covering the one or more solar cell elements between the third surface and the solar cell portion, the second filler layer comprising a resin;
• a substrate having a fifth surface facing the fourth surface;
• and
• an adhesive layer bonding the fourth surface and the fifth surface together between the fourth surface and the fifth surface,
• wherein the first protective layer is softer than the substrate, and
• one or more of the second filler layer, the second protective layer, and the adhesive layer have a higher Young's modulus than the first filler layer.
