    Abstract: There is disclosed a method of preparing a photovoltaic device. In particular, the method comprises integrating epitaxial lift-off solar cells with mini-parabolic concentrator arrays via a printing method. Thus, there is disclosed a method comprising providing a growth substrate; depositing at least one protection layer on the growth substrate; depositing at least one sacrificial layer on the protection layer; depositing at least one photoactive cell on the sacrificial layer; etching a pattern of at least two parallel trenches that extend from the at least one photoactive cell to the sacrificial layer; depositing a metal on the at least one photoactive cell; bonding said metal to a host substrate; and removing the sacrificial layer with one or more etch steps. The host substrate can be a siloxane, which when rolled, can form a stamp used to integrate solar cells into concentrator arrays. There are also disclosed a method of making a growth substrate and the growth substrate made therefrom.

    Abstract: A device comprising a thin film solar cell with an integrated flexible antenna, such as a meander line antenna, is disclosed. In an embodiment, the device comprises a substrate and an array of solar cells disposed on the substrate, wherein the array of solar cells are interconnected by metal conductors that carry DC power from the solar cells and which form at least part of the flexible antenna. In their capacity as an antenna, the metal conductors operate cooperatively with the solar cells to radiate an RF signal, receive an RF signal, or both radiate and receive an RF signal. The device optionally comprises a choke disposed on the substrate and electrically coupled to the array of solar cells, wherein the choke operates to impede conduction of the RF signal. A method of making the disclosed device is also disclosed.
