FABRIC STRUCTURE COMPRISING FLEXIBLE SOLAR CELLS

Abstract

A fabric structure includes a woven polyester fabric and a layer of butyl rubber disposed on the woven polyester fabric. The fabric structure includes a layer of polyacrylonitrile attached to the butyl rubber layer. The fabric structure includes at least one flexible thin-film solar cell element located on the polyacrylonitrile layer. The fabric structure includes a plurality of electrical connecting lines extending between the polyacrylonitrile layer and the butyl rubber layer and connected to the at least one solar cell element. The fabric structure forms part of a device, such as a convertible top, a carport covering, a sun shade, or a boat sail.

Description

BRIEF DESCRIPTION OF THE FIGURE

[0019] The invention is schematically illustrated in the drawing on the basis of one embodiment and described further with reference to the drawing. In the figure:

[0020] FIG. 1 shows an embodiment of the fabric structure according to the invention.

DETAILED DESCRIPTION

[0021] FIG. 1 shows an embodiment of the fabric structure 10 according to the invention. A layer 12 of butyl rubber is disposed on a polyester fabric 11, to which layer a layer 13 made of polyacrylonitrile is attached. At least one, flexible, thin-film solar cell element 14, the electrical connecting lines 15 of which extend between the polyacrylonitrile layer 13 and the butyl rubber layer 12, is located on the layer 13 of polyacrylonitrile. The electrical connecting lines 15 are connected at one end to the thin-film solar cell element 14, and at the other end to a connection plug 18. The flexible, thin-film solar cell element 14 is attached to the layer 13 of polyacrylonitrile by means of an adhesive layer 16 or a printing paste 16. In the embodiment shown, a transparent protective layer 17, e.g., a transparent protective film, is attached to the flexible, thin-film solar cell element 14. In another embodiment, the transparent protective layer 17 consists of a transparent and flexible casting resin.
