Abstract
A flexible solar cell comprises an epitaxially grown III-V layer having a first layer grown on a base substrate, at least one intermediate layer grown on the first layer, and a cap layer grown on the at least one intermediate layer, the III-V layer being separated from the base substrate by controllably spalling the first layer from the base substrate; and a flexible substrate coupled to the epitaxially grown III-V layer. The flexible solar cell may be used to provide power to an electronic device.
