Abstract

A contoured solar generator whose solar cells and their associated electrical terminals and connecting lines are embedded in a laminate including at least the solar cells, an elastic thermosetting adhesive foil and a glass pane. To adapt the solar generator to a given external contour or to fit it into a given contour, the solar generator is configured as a curved laminate including at least one-dimensionally bent solar cells.

Claims

1. A contoured solar generator with associated electrical terminals and connecting lines, comprising:

a curved laminate composed of solar cells bent in at least one dimension, an elastic thermosetting adhesive foil in which said solar cells are embedded, and a curved glass pane overlaying one face of said elastic thermosetting adhesive foil.

2. The contoured solar generator set forth in claim 1, including a curved substrate overlaying an opposite face of said elastic thermosetting adhesive foil from said face overlaid by said curved glass pane.

3. The contoured solar generator set forth in claim 2, wherein said curved substrate and curved glass pane are thermally preformed and are manufactured in pairs.

4. The contoured solar generator as set forth in claim 3, wherein said curved substrate is a second glass pane.

5. The contoured solar generator as set forth in claim 4, wherein said curved substrate is a second glass pane and said curved laminate forms at least part of a vehicle window.

6. The contoured solar generator as set forth in claim 4, including chemically hardened glass panes.

7. The contoured solar generator as set forth in claim 4, including thermally hardened glass panes.

8. The contoured solar generator as set forth in claim 3, wherein said curved substrate is a sheet metal substrate.

9. The contoured solar generator as set forth in claim 3, wherein said curved substrate is a thin sheet.

10. The contoured solar generator as set forth in claim 9, wherein said curved substrate is a thin transparent sheet.

11. The contoured solar generator as set forth in claim 2 wherein said curved laminate is an integral component of a vehicle.

12. The contoured solar generator as defined in claim 2, wherein said curved laminate is a vehicle sun roof.

13. The contoured solar generator as set forth in claim 2, wherein said curved laminate is a vehicle spoiler.

14. The contoured solar generator as set forth in claim 2, wherein said glass pane is of white glass.

15. A method of producing a solar generator as set forth in claim 2, comprising:

preforming a substrate and a glass pane to a selected curvature to form a curved pre-laminate;

inserting solar cells and a thermosetting adhesive foil between said substrate and said glass pane;

applying external mechanical pressure on said substrate and on said glass pane to adapt said solar cells and thermosetting adhesive foil approximately to the curvature of said pre-laminate; and

bonding said thermosetting adhesive foil and said solar cells to said curved substrate and said curved glass pane in a hot vacuum process to form a curved laminate.

16. The contoured solar generator as set forth in claim 1, wherein the curved laminate is adapted to the aerodynamic shape of the vehicle.

17. A contoured solar generator, comprising:

a curved laminate composed of solar cells bent in at least one dimension, an elastic thermosetting adhesive foil in which said bent solar cells are embedded, a curved thin transparent sheet overlaying one face of said elastic thermosetting adhesive foil, and a curved substrate overlaying an opposite face of said elastic thermosetting adhesive foil from said face overlaid by said curved thin transparent sheet.
