Back sheet for solar cell and process for production thereof, and solar cell module |
摘要 |
The present invention provides a back sheet for a solar cell, the back sheet including a polymer base and a polymer layer that is disposed by coating on at least one surface of the polymer base material, the polymer layer including an amorphous colloidal silica and, as a binder, at least one of a polymer selected from a fluorine-based polymer or a silicone-based polymer, the polymer formed by coating having excellent uniformity and the back sheet having superior weather resistance compared to conventional back sheets. |

1. A back sheet for a solar cell, the back sheet comprising:
a polymer base; and a polymer layer that is provided on at least one surface of the polymer base, that includes, as a binder, a polymer selected from a fluorine-based polymer or a silicone-based polymer, and that includes a colloidal silica in which plural spherical particles are linked together to form a chain-like shape, wherein a total amount of the fluorine-based polymer and the silicone-based polymer in the polymer layer is in a range of from 0.5 g/m2 to 9.0 g/m2. |
