Abstract
Presently described are methods of making coating comprising aqueous fluoropolymer latex dispersions, aqueous fluoropolymer coating compositions, coated substrates, and (e.g. backside) films of photovoltaic cells. In one embodiment, the film comprises at least one fluoropolymer comprising repeat units derived from VF, VDF, or a combination thereof; inorganic oxide nanoparticles; and a compound that reacts with the repeat units derived from VF and VDF to crosslink the fluoropolymer and/or couple the fluoropolymer to the inorganic oxide nanoparticles. In another embodiment, the backside film comprises at least one fluoropolymer comprising repeat units derived from VF, VDF, or a combination thereof; and an amino-substituted organosilane ester or ester equivalent crosslinking compound.
