Problems solved by technology

[0011] However, the dyed electrode layer inevitably reduces the transparency, so the light energy that can be absorbed by the light conversion layer is reduced
In addition, dyes or pigments in the sealant layer (e.g., EVA layer) can significantly reduce the adhesive strength of the BIPV module to the building's enclosure, especially when the BIPV module will be installed on glass materials

Embodiment Construction

[0038] The present invention is explained in detail below by way of examples with reference to the figures, which do not intend to limit the scope of the present invention. It will be appreciated that any modification or alteration readily apparent to those skilled in the art falls within the scope of the disclosure of the specification.

[0039] One aspect of the present invention is to provide a novel colored backsheet for a BIPV module.

[0040] The color backsheet according to the invention comprises a PET film, a barrier layer and a fluoropolymer film.

[0041] PET film is used to provide electrical insulation. The PET film shall have at 10 12 ohm-cm to 10 15 Volume resistivity in the ohm-centimeter range.

[0042] Barrier layers such as aluminum foil are used to provide moisture resistance. The moisture permeability of Al foil is lower than 10 -4 grams / square meter day. The thickness of the barrier layer is not particularly limited, and is preferably 10 μm to 100 ...

Abstract

The present invention provides a color backsheet for a building-integrated photovoltaic (BIPV) module comprising a polyethylene terephthalate (PET) film, a barrier layer and a fluorine-containing polymer film, at least one of the films being doped with dyes or pigments. The present invention also provides a color BIPV module comprising the color backsheet according to the present invention.

Description

technical field [0001] The invention relates to a color building integrated photovoltaic (BIPV) module. More specifically, the present invention relates to the manufacture of a colored backsheet useful in colored BIPV modules. Background technique [0002] BIPV is a photovoltaic material that is used in particular to replace traditional building materials in parts of building enclosures such as roofs, skylights or facades. BIPV is increasingly being incorporated into the fabric of buildings as a secondary or even primary power source. BIPVs can be multicolored and visually striking, and because BIPVs are an integral part of the design, they generally blend better than other solar devices. Over the past decade, BIPV has proven to be an effective building energy technology in residential, commercial, industrial and institutional buildings and structures. [0003] BIPV also achieves sunshade and protection from wind and rain. Plus, the unventilated BIPV modules provide ther...
