    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： In aspects of the present invention, a method is disclosed to form a lamina having opposing first and second surfaces. Heavily doped contact regions extend from the first surface to the second surface. Generally the lamina is formed by affixing a semiconductor donor body to a receiver element, then cleaving the lamina from the semiconductor donor body wherein the lamina remains affixed to the receiver element. In the present invention, the heavily doped contact regions are formed by doping the semiconductor donor body before cleaving of the lamina. A photovoltaic cell comprising the lamina is then fabricated. By forming the heavily doped contact regions before bonding to the receiver element and cleaving, post-bonding high-temperature steps can be avoided, which may be advantageous.

    摘要翻译： 在本发明的方面，公开了一种形成具有相对的第一和第二表面的薄片的方法。 重掺杂的接触区域从第一表面延伸到第二表面。 通常，通过将半导体施主体附着到接收器元件，然后从半导体施主体分离薄层而形成薄片，其中薄片保持固定在接收器元件上。 在本发明中，重掺杂的接触区域通过在切割层之前掺杂半导体施主体形成。 然后制造包括层板的光伏电池。 通过在接合元件接合之前形成重掺杂的接触区域并且断开，可以避免后接合高温步骤，这可能是有利的。
