Abstract
A solar cell module includes a solar cell string, a first encapsulant, a second encapsulant having a viscoelasticity greater than a viscoelasticity of the first encapsulant, a front-side protective plate, and a back-side protective sheet. The solar cell string includes a plurality of solar cells and a line member which electrically connects the plurality of solar cells. The lengthwise direction of the line member is different from the maximum expansion and contraction direction of the back-side protective sheet.
Claims4
A solar cell module comprising:
- a front-side protective plate disposed on a light entering side;
- a first encapsulant;
- a solar cell string;
- a second encapsulant;
