Abstract: The present invention provides a thin film photovoltaic device comprising a poly(vinyl butyral) layer that provides excellent adhesion, resistivity, sealing, processability, and durability to the device.

Abstract: The present invention provides multiple layer glazing bilayers that utilize a masking layer over the polymer film component. The masking layer is specifically formulated to have a melting point that is less than the temperature employed in the autoclave process that is used to laminate the bilayer. The surprising result of the use of the specified masking layer of the present invention is a bilayer that can be processed according to conventional lamination methods but with a reduction in the damage and optical defects that normally occur during processing and installation of the bilayer product. After installation, the masking layer can be removed, exposing the previously protected, underlying polymer film.

Abstract: The present invention is in the field of multiple layer glass panels having multiple polymer layers disposed thereon, and more specifically, the present invention is in the field of multiple pane windows having multiple polymer layers disposed thereon wherein a moisture barrier layer is included.

Abstract: The present invention includes infrared absorbing agents that have been treated to resist hydrolytic effects caused by elevated moisture, interlayers comprising those agents, and various multiple layer glass panels that comprise those interlayers.
