ENVIRONMENTALLY FRIENDLY BACKSHEET FOR PHOTOVOLTAIC MODULE AND METHOD OF MANUFACTURING THE SAME |
摘要 |
Provided are a backsheet for a photovoltaic module, a method of manufacturing the same, and a photovoltaic module. As a resin layer including a fluoropolymer is formed by coating an aqueous dispersion composition including a crystalline fluoropolymer, a pigment, an aqueous dispersion binder and water on a substrate by an in-line coating process in a process of manufacturing the substrate, a process of manufacturing the backsheet may be simplified. In addition, since the process of manufacturing the backsheet does not use a toxic organic solvent, the process may be environmentally friendly and economical, and may enhance both productivity and product quality. |

1. A backsheet for a photovoltaic module, comprising:
a resin layer formed by coating a crystalline fluoropolymer on a substrate by an in-line coating process, wherein an adhesive strength measured by a cross-cut test performed according to ASTM D3002/D3359 after the backsheet is left in an oven maintained at 2 atm, 121° C. and 100% R.H. for 75 hours is at least 4B. |
