    摘要： A very thin photovoltaic cell is formed by implanting gas ions below the surface of a donor body such as a semiconductor wafer. Ion implantation defines a cleave plane, and a subsequent step exfoliates a thin lamina from the wafer at the cleave plane. A photovoltaic cell, or all or a portion of the base or emitter of a photovoltaic cell, is formed within the lamina. In preferred embodiments, the wafer is affixed to a receiver before the cleaving step. Electrical contact can be formed to both surfaces of the lamina, or to one surface only.

    摘要： A semiconductor donor body is affixed to a receiver element, and a thin semiconductor lamina is cleaved from the donor body, remaining affixed to the receiver element. A photovoltaic assembly is fabricated which includes the lamina and the receiver element, wherein a photovoltaic cell comprises the lamina. The bond between the semiconductor donor body and the receiver element must survive processing to complete the cell, as well as eventual assembly, transport, and operation in a finished photovoltaic module. It has been found that inclusion of a conductive layer such as titanium or aluminum aids bonding between the semiconductor donor body and the receiver element. In some embodiments, the conductive layer may also serve as an electrical contact and/or as a reflective layer.
