ABSTRACT:
A donor silicon wafer may be bonded to a substrate and a lamina cleaved from the donor wafer. A photovoltaic cell may be formed from the lamina bonded to the substrate. An intermetal stack is described that is optimized for use in such a cell. The intermetal stack may include a transparent conductive oxide layer serving as a quarter-wave plate, a low resistance layer, an adhesion layer to help adhesion to the receiver element, and may also include a barrier layer to prevent or impede unwanted diffusion within the stack.
