Stretchable photovoltaic devices and carriers
A stretchable photovoltaic device, a stretchable photovoltaic module and a carrier for facilitating formation of a stretchable photovoltaic device and/or module are provided. The stretchable photovoltaic device includes a stretchable part, at least one photovoltaic cell and a surface over which that at least one photovoltaic cell is disposed. The stretchable part has a given length that is operable to change in response to a force being applied to the device. The given length may, for example, elongate when the force causes the device to elongate. Alternative and/or additionally, the given length may compress when the force causes the device to compress.
1. A stretchable photovoltaic module comprising:
first and second stretchable photovoltaic devices, wherein the first stretchable photovoltaic device overlays the second stretchable photovoltaic device such that electromagnetic radiation can pass through the first photovoltaic device and impinge the second stretchable photovoltaic device, and wherein:
the first stretchable photovoltaic device comprises:
a first stretchable part having a first stretchable-part length, wherein the first stretchable-part length is operable to change in response to a force being applied to the device, wherein the first stretchable part comprises a plurality of corrugations, wherein the plurality of corrugations are formed from a substantially non-elastic metal or plastic material that can bend, and wherein the change in the stretchable-part length is produced by a change in an amplitude and width of at least some of the plurality of corrugations;
at least one first photovoltaic cell; and
a first mounting site having a first foundation surface over which the at least one first photovoltaic cell is disposed; and
the second stretchable photovoltaic device comprises:
a second stretchable part having a second stretchable-part length, wherein the second stretchable-part length is operable to change in response to the force being applied the device, wherein the second stretchable part comprises a plurality of corrugations, wherein the plurality of corrugations are formed from a substantially non-elastic metal or plastic material that can bend, and wherein the change in the stretchable-part length is produced by a change in an amplitude and width of at least some of the plurality of corrugations;
at least one second photovoltaic cell; and
a second mounting site having a second foundation surface over which the at least one second photovoltaic cell is disposed.
2. The module of claim 1 , wherein the first stretchable photovoltaic device further comprises at least one aperture, and wherein the second stretchable photovoltaic device is positioned below the first stretchable photovoltaic device so as to align the at least one second photovoltaic cell and the aperture to allow electromagnetic radiation to pass through the aperture and impinge the at least one second photovoltaic cells.
3. The module of claim 2 , wherein the electromagnetic radiation comprises first and second parts, wherein the first part defines a first range of frequencies, wherein the second part defines a second range of frequencies, wherein the second part is at least partially transmitted through the first photovoltaic device, and wherein the second stretchable photovoltaic device is positioned below the first stretchable photovoltaic device so as to align the at least one second photovoltaic cell and the at least one first photovoltaic cell to allow (i) the first part to impinge the at least one first photovoltaic cell, and (ii) the second part to impinge the at least one second photovoltaic cell.
4. The module of claim 1 , wherein the first stretchable part comprises at least one of a flexible foil, film, sheet, wire, or a spring.
5. The module of claim 1 , wherein the second stretchable part comprises at least one of a flexible foil, film, sheet, wire, or a spring.
6. The module of claim 1 , wherein the first and second stretchable parts further comprise a plurality of layers of metal or plastic material.
