Abstract
The invention relates to architectural substrates coated with a polyvinylidene fluoride (PVDF) dispersion coating to produce a weatherable material. One specific use is as a PVDF coating on a frontsheet or backsheet of a photovoltaic module for capturing and using solar radiation. The polyvinylidene fluoride coating is exposed to the environment and provides chemical resistance, low water vapor transmission, electrical insulation, and UV light protection.

A photovoltaic module, comprising:
- a) an outer transparent glazing material;
- b) encapsulated interconnected solar cells;
- and
- c) a backsheet comprising a support substrate coated on the side exposed to the environment, or both sides with a dispersion fluoropolymer composition comprising a mixture of a fluoropolymer and a non-functionalized acrylic.
A photovoltaic module, comprising:
- a) an outer transparent glazing material;
- b) encapsulated interconnected solar cells;
