TECHNOLOGY FOCUS - ELECTRONICS - Preferred Method: In the method above, forming the stretchable carrier comprises depositing at least one of metal or plastic over a form. The stretchable part comprises at least one corrugation, and where the at least one of the metal or the plastic is deposited over the form so as to make a foil in the form of the at least one corrugation. Depositing the PV cell comprises forming a PV stack having a junction of n-type and p-type semiconductor layers. Forming the PV stack comprises depositing a back-contact layer; depositing the n-type and p-type semiconductor layers over the back-contact layer; depositing a font-contact layer over the n-type and the p-type semiconductor layers; and forming first and second conductors coupled to the front-contact layer and the back-contact layer, respectively. Interconnecting comprises: depositing metal to form connections between the first and second conductors and first and second ones of the output terminals, respectively. Interconnecting comprises: forming wire-bonds between the first and second conductors and first and second ones of the output terminals, respectively. Forming the stretchable carrier comprises: forming a mounting site coupled to the stretchable part, where the mounting site defines the surface to which to affix the PV cell. Forming the stretchable carrier comprises: forming an aperture disposed adjacent to the mounting site and the stretchable part. The stretchable part comprises first and second stretchable parts, and where the first stretchable part is oriented orthogonally to the second stretchable part. Forming a stretchable PV device comprises forming a stretchable carrier including a mounting site and a stretchable part having a given length, the given length being operable to change in response to a force being applied to the stretchable carrier; forming a PV cell; combining the PV cell with the stretchable carrier; and interconnecting the PV cell to output terminals. Forming the stretchable carrier comprises depositing at least one of metal or plastic over a form so as to make a foil in the form of the stretchable part and the mounting site. Forming the stretchable carrier comprises forming at least one of metal or plastic in a first foil to form the stretchable part; forming at least one metal or plastic in a second foil to form the mounting site; and joining the first foil and the second foil. Forming the at least one PV cell comprises forming a PV stack on a substrate, the PV stack having a junction of n-type and p-type semiconductor layers. Forming the PV stack comprises depositing a back-contact layer; depositing the n-type and p-type semiconductor layers over the back-contact layer; depositing a font-contact layer over the n-type and the p-type semiconductor layers; and forming first and second conductors coupled to the front-contact layer and the back-contact layer, respectively. Interconnecting comprises depositing metal to form connections between the first and second conductors and first and second ones of the output terminals, respectively. Interconnecting comprises forming wire-bonds between the first and second conductors and first and second ones of the output terminals, respectively. Combining the PV cell with the stretchable carrier comprises attaching the PV cell to the mounting site.
